What is the Maintenance of a Diesel Generator Set?


Maintenance on a deutz diesel generator set is about the same as owning a diesel powered car. Routine maintenance like oil, oil filter, air filter, and fuel filter. For cold  and tropical climates it is advise to have a water-fuel separation filter system installed. The worse enemy of a diesel generator set is moisture because the water properties create advance ignition and accelerated detonation.
Maintenance on diesel generators requires you start up and exercise your generator set.. Setting up a regular program for starting up your diesel generator set is the prefer way. How much, depends, the bigger the diesel generator set the bigger the engine and expense for operation and consumables. Most manufactures recommend exercising the genset for about a half-hour of run time, once a week. You will want it to run long enough  to heat up all the components.
The engine oil will need to be change every 100 to 250 hours depending on the dust conditions. Changing the oil filter every time you change the oil is another good practice for the maintenance on a diesel generator set. Air filters need to changed and diesels generator set need a lot of clean air to operate properly. You should check the air filter every 100 hours and every 50 hours in dusty environments. Setting up a regular scheduled maintenance service is the key to long-life and performance for your genset.
The generator end of a diesel generator set requires no service unless you live in a dusty environment. The maintenance on a diesel generator set in a dusty environment is to use a high pressure air hose and occasionally blow out the dust from the generator system. Dirt and dust particles can cause shorts in the internal wiring coating. High heat and dust are enemy of power generator.
In the aftermath of the recent storms along the southern coast line of the US that as many as one-third of the backup deutz diesel generators didn't start. Most of this was from the lack of little or no maintenance performed since the unit was installed. Many owners thing the cost of regular maintenance is to high. My question is what the cost of installing a genset that doesn't work when needed?

Installation of a diesel generator set


When purchasing a lovol diesel generator set it will come with a detailed installation guide. We do strongly recommend that the installation of a diesel generator set be performed by a licensed electrical or mechanical contractor. Their expertise and the understanding of regulation and local codes will save you money in the long run. Should you chose to install it yourself, please do your homework and obtain the proper permits required by your local authorities.   It is extremely important to have all codebooks for reference and to adhere to the laws. Your system must be inspected before starting to prevent fires and explosions from improper installation.
While all Diesel generator sets have some basic requirements, each brand and model has unique installation requirement, so we will not give detail installation of a diesel generator set. We will provide you with important  information you need to take in consideration before the placement of your diesel generator set.
   Location
To determine a suitable location for your generator set there are many aspects you will need to take in consideration. Access, space for maintenance, noise, ventilation, exhaust piping, fuel piping, humidity, and temperature are all factors that must be considered. A location where temperature conditions are controlled and noise isolation from main working areas is preferred. A tailwater gallery locations is frequency used for a generator set.
  Access
Personnel access should be convenient for routine inspections. Access for installation and replacement of the unit should be taken in consideration. Future equipment installation or construction should not hinder the access for the replacement of parts or the complete diesel generator unit.
  Maintenance
Adequate space should be provide for normal maintenance and overhaul of the diesel generator set.
  Noise
A location away from principal working areas or offices and typically a generator set comes with the calculate dBA levels at full load operation. This is the honest way to report the noise level. Vibration of an diesel generator set should be taken in consideration and kept away from quiet working location. 
  Ventilation
The room or space where the generator operates, should not exceed 100 degrees. Generators installations require an intake of cool, clean air and an outlet vent for hot air. The size of the space affects room temperature. A Generator in a small space  will affect the room temperature and may require extra ducting. Increasing the vent sizes may cool the room down and ensure a positive airflow. Moist air is corrosive to a generator set, so make sure inlets are positioned to minimize moisture intake. High humidity can be damaging to lovol diesel generators so a below tailwater galleries is undesirable.

Why Should I Choose a Diesel Powered Engine or Generator?


In today's world, where fuel prices are increasing as a consequence of spiraling demand and diminishing supply, you need to choose a cost effective fuel to meet your needs. Thanks to the invention of perkins diesel generator, the diesel engine has proved to be extremely efficient and cost effective.  Diesel fuel is priced moderately higher than gasoline but diesel has a higher energy density, i.e. more energy can be extracted from diesel as compared with the same volume of gasoline. Therefore, diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is heavier and oilier compared with gasoline, and has a boiling point higher than that of water.  And diesel engines are attracting greater attention due to higher efficiency and cost effectiveness.

How Does a Diesel Engine Work?

The distinction lies in the type of ignition.  While gasoline engines operate on spark ignition, diesel engines employ compression - ignition for igniting the fuel. In the latter, air is drawn into the engine and subjected to high compression that heats it up. This results in a very high temperature in the engine, much higher than the temperature attained in a gasoline engine. At peak temperature and pressure, diesel that is let into the engine ignites on account of the extreme temperature.

In a diesel engine, air and the fuel are infused into the engine at different stages, as opposed to a gas engine where a mixture of air and gas are introduced. Fuel is injected into the diesel engine using an injector whereas in a gasoline engine, a carburetor is used for this purpose. In a gasoline engine, fuel and air are sent into the engine together, and then compressed. The air and fuel mixture limits fuel compression, and hence the overall efficiency. A diesel engine compresses only air, and the ratio can be much higher. A diesel generator set compresses at the ratio of 14:1 up to 25:1, whereas in a gasoline engine the compression ratio is between 8:1 and 12:1. After combustion, the combustion by-products are removed from the engine through the exhaust. For starting during cold months extra heat is provided through 'glow plugs'.

Diesel engines can either be two cycle or four cycle and are chosen depending on mode of operation. Air-cooled and liquid-cooled engines are the variants to be chosen appropriately.  It is preferable to use a liquid-cooled generator as it is quiet in operation and has evenly controlled temperature. 

Advantages of a Diesel Engine

The diesel engine is much more efficient and preferable as compared with gasoline engine due to the following reasons:

• Modern diesel engines have overcome disadvantages of earlier models of higher noise and maintenance costs.  They are now quiet and require less maintenance as compared with gas engines of similar size.
• They are more rugged and reliable.
• There is no sparking as the fuel auto-ignites. The absence of spark plugs or spark wires lowers maintenance costs. 
• Fuel cost per KiloWatt produced is thirty to fifty percent lower than that of gas engines.
• An 1800 rpm water cooled diesel unit operates for 12,000 to 30,000 hours before any major maintenance is necessary. An 1800 rpm water cooled gas unit usually operates for 6000-10,000 hours before it needs servicing.
• Gas units burn hotter than diesel units, and hence they have a significantly shorter life compared with diesel units.

Applications & Uses for Diesel Engines

Diesel engines are commonly used as mechanical engines, perkins diesel generators and in mobile drives. They find wide spread use in locomotives, construction equipment, automobiles, and countless industrial applications.  Their realm extends to almost all industries and can be observed on a daily basis if you were to look under the hood of everything you pass by. Industrial diesel engines and diesel powered generators have construction, marine, mining, hospital, forestry, telecommunications, underground, and agricultural applications, just to name a few. Power generation for prime or standby backup power is the major application of today's diesel generators.  Check out our article on the various types of engines and generators and their common applications for more examples.

How to Determine What Size You Need


Getting a generator that can handle all your power generation needs is one of the most critical aspects of the purchasing decision.  Whether you are interested in prime or standby power, if your new generator can't meet your specific requirements then it simply won't be doing anyone any good because it can put undue stress on the unit and even damage some of the devices connected to it.  Unfortunately, determining exactly what size of perkins diesel generator to get is often very difficult and involves a number of factors and considerations. 

Making a choice amongst single phase, three phase, kW, KVA, welder, standby or motor starting generators can be mind-boggling. To prevent such confusion, this article was developed to help you get a better idea of how the sizing process works and some key things to keep in mind.  This is not a substitute for a certified electrician, which we always suggest talking to before buying, but it should provide you with enough information to get a solid understanding of some of the key things that are involved.
Generator Size Variations:  With the latest advancements in the field of electrical engineering, generators are now available in a wide range of sizes. Generators with power supply capacities of 5kW to 50kW are readily available in the personal and home use markets, while industrial generators are anywhere from 50kW to over 3 Megawatts.  Handy and portable gensets are available for homes, RV's and small offices, but larger businesses, data centers, buildings, plants, and industrial applications need to use the much larger sized industrial diesel generators to meet their higher power requirements.
Generator Sizing - How Much Power?:  Many people believe smaller generators can be used for standby electric power because they are not running all the time. This is not only a myth but can actually be very detrimental. Unfortunately, generator under sizing is one of the most common mistakes committed by buyers.  Not only does it involve the risks of damaging your new asset (the generator), but it can also damage other assets connected to it, create hazardous situations, and even limit overall productivity of the unit and/or the business relying on it.  If nothing else, the key thing to remember here is that more is always better than less.  
How to Determine the Right Size Engine or Generator: While there is no substitute for having a certified electrician perform an inspection and calculate everything for you, the guidelines below do offer some great starting points and should at least get you started in the right direction:
Know Your Requirements:  Going to a dealer and buying the best or cheapest generator available without any other consideration is clearly not the best approach. It is always better to delve deep into your power generation requirements before making a choice. You can do this in the following ways:
- Make a list of the items that need to be powered by the generator
- Make a note of the starting and running wattage of the respective items
- Calculate the total power requirements in KVA or KW
How to Find the Starting and Running Wattage: Getting the right starting and running wattage of the devices you intend to power is crucial for calculating the accurate power requirements. Normally, you will find these in the identification plate or the owner's manual in the buyer's kit of each respective device, tool, appliance, or other electrical equipment.
Ampere - Watt Conversion:  You may often find power requirements of tools stated in amperes. In order to convert the power requirement of a tool from ampere to watts, follow these calculations, or you can also use our handy conversion tool on our power calculator web page.
For resistive load: Wattage = amperes x volts
For reactive load: Wattage = (amperes x volts) x load factor
Power Requirement Charting: It often happens that you lose the owner's manual or for some reason can't find the power requirement specification of the tools and/or other electrical devices you're running. Here is a sample power consumption chart that demonstrates some of the typical wattages used for common appliances and tools.  The chart is simply provided as an example to demonstrate how starting and running wattages differ, and how each device has specific consumption needs.  If you have questions over any particular items you can contact the manufacturer, consult an electrician, or contact us for a free consultation.
Different ways of Calculating:  Depending upon the type and number of devices, and the way the generator is scheduled to be used, there are a few different ways of calculating power requirements:
-  Single motor running
-  Multiple motors running simultaneously
-  No electric motors.
Advantages of choosing the right size generator: Now that you have an idea on how to choose the appropriate size of perkins diesel generators to suit your needs.

What are the important things to consider when purchasing a diesel generator?


A generator is a major purchase and for most residential applications a quality generator will last a life time when used for standby/emergency backup. Save yourself some grief and buy only a major brand yanmar diesel generator. We do not know why people buy "off brand" engine, which you can not obtain the necessary parts, service and support. A cheap or bargin price is sometimes an expensive lesson.
Type of generator set.If your backup requirements are just occasional and you only need limited power an inexpensive generator set will meet your need. A air-cooled gas gensets could meet all your needs. If you live anywhere like Florida, East Coast or any coastal area you will need a high quality diesel generator set. Most diesel models are reliable and fuel efficient. An 1800 rpm model will provide better fuel efficiency and will have a longer life but cost more.  If you buy a diesel generator set remember regular maintenance and exercising it by letting it run for a half hour, will make sure it will be ready to use when you need it.
Maintenance and repairs of yanmar diesel generators.A genset is a mechanical and electrical device that over time will need some service or parts. The generator end is the usually the first item to fail with heavy use. The insulation coatings on the windings are based on heat ratings and H is best and F is good. Some major brands manufacture their own generator ends and parts, and repair is usually only available through them. But many use off-the-shelf brands and are readily available and any repair center can service the generator end.

Industrial Diesel Engine Types & Applications


Types of Diesel Engines

There are two classes of diesel engines: two-stroke and four-stroke. Most diesel engines generally use the four-stroke cycle, with some larger engines operating on the two-stroke cycle.  Normally, banks of cylinders are used in multiples of two, though any number of cylinders can be used as long as the load on the crankshaft is counterbalanced to prevent excessive vibration.
Isuzu diesel generator produce either single or three phase power. Most homeowners require single phase whereas industrial or commercial applications usually require three phase power. Diesel engine generators are recommended due to their longevity and lower operating costs. Modern diesel engines are quiet and generally require much less maintenance than comparably sized gas (natural gas or propane) units.

Diesel Engine Generators - Commercial/Industrial Applications

Diesel generators are designed to meet the needs of small and medium-sized businesses apart from heavy usage in industries. A diesel generator is a revolutionary product that brings clean and affordable standby power within the reach of millions of enterprises, homes and small businesses. Reducing the cost of backup power and making generators easy to install is becoming the norm these days. 
Businesses lose money when they shut down during a blackout.  Considering the impact of significant revenue loss, the economics of investing in standby power is compelling. To illustrate the point: If a retail business averages $1000 an hour at the cash register, the loss of revenue during an extended outage will be very high, not to mention the cost of having employees idle during that time.  However, diesel powered generators eliminate the risk of a blackout. Add the advantages of being open while competitors without backup power are shut down and the cost / benefit analysis looks even better.  Investing in generators is a simple way to safeguard revenue, maintain security, avoid losses, and protect the bottom line.
Most modern generators are engineered to meet emergency power needs. These units continuously monitor the electrical current and automatically start up if power is interrupted and shut off when utility service is returned. In industries, during critical processes, generators can supply emergency power to all vital and selected loads as desired. This quality leads to widespread use of diesel-powered generators across recreational, residential, commercial, communication, and industrial applications. Today, most state-of-the-art- hospitals, five star hotels, business process outsourcing centers, manufacturing plants, telecommunications organizations, commercial buildings, data centers, emergency facilities, large industries, and mining companies require uninterrupted power and have backup diesel engine generators.
On the Road:
The vast majority of modern heavy road vehicles like trucks and buses, ships, long-distance trains, large-scale portable power generators, and most farm and mining vehicles have diesel engines. However, in some countries they are not nearly as popular in passenger vehicles as they are heavier, noisier, have performance characteristics that make them slower to accelerate. In general, they are also more expensive than petrol vehicles. Modern diesel engines have come a long way and with Turbo Direct Injection systems now in vehicles, one would be hard-pressed to notice a difference between diesel and gasoline engines.
In some countries, where tax rates make diesel fuel much cheaper than petrol, diesel vehicles are very popular. Newer designs have significantly narrowed differences between petrol and diesel vehicles in these areas. The BMW diesel lab in Austria is considered to be the worldwide leader in the development of automotive diesel engines. After a long spell with relatively few diesel cars in its lineup, Mercedes Benz has returned to diesel-powered cars in the 21st century with an emphasis on high performance.
In the agricultural field, tractors, irrigation pumps and threshing machines and other equipment are predominantly diesel powered. Construction is another sector that relies heavily on diesel power. All concrete pavers, scrapers, rollers, trenchers and excavators run on diesel.   
In the Air:
A few airplanes have been using diesel engines since the late 1930s. The newer automotive diesel engines have power-weight ratios comparable to the ancient spark-ignition designs and have far superior fuel efficiency. Their use of electronic ignition, fuel injection, and sophisticated engine management systems also makes them far easier to operate than mass-produced spark-ignition aircraft engines. The cost of diesel fuel compared to petrol has led to considerable interest in diesel-powered small general aviation planes, and several manufacturers have recently begun selling diesel engines for this purpose.
On the Waters:
High-speed engines are used to power tractors, trucks, yachts, buses, cars, compressors, generators and pumps. The largest diesel engines are used to power ships and liners along the high seas. These huge engines have power outputs up to 90,000 kW, turn at about 60 to 100 rpm, and are 15 meters tall.
Under the Ground:
The mining and mineral extraction sector worldwide relies heavily on diesel power to harness natural resources such as aggregates, precious metals, iron ore, oil, gas, and coal. Diesel-powered shovels and drills excavate these products and load them into enormous mining trucks or onto conveyer belts that also operate on the same fuel. Overall, diesel accounts for 72 percent of the energy used by the mining sector. 
Both surface and underground mining operations rely on diesel-powered equipment to extract materials and load trucks. The largest rubber-tired, diesel-powered equipment used in mining are enormous off-road trucks with engines of over 2,500 horsepower, capable of hauling over 300 tons per load. These giant trucks trundling across the land are a sight to behold.
In the Hospitals
Emergency backup generators are a must have for any major medical healthcare facilities.  Due to the critical nature of the work these facilities do and the position their patients are in, power failures are simply not an option. For many years, both military and public hospitals have relied on industrial strength generator sets to take over whenever the power goes out, whether it's from a local outage or major natural disaster like a hurricane or flood.   
Behind the Datacenters

Computers are at the heart of today's industry.  When servers and systems go down, communications can be lost, business stops, data is lost, workers sit idle, and just about everything comes to a hault.  It is for that reason that almost all communications and telecommunications companies of all shapes turn to isuzu diesel generators as their primary backup power option.  With the reliability of their services affecting so many people, they really have no choice but to have a solid backup power option in place for both their business, and the

How is the noise level calculated on generators?


Noise level or dBA levels are calculated by doosan diesel generator manufacturer at full load operation.  The USA standard is based on the sound level at 21 feet while the European standard is based on the sound level at 23 feet. In this article, we explain each  5 levels by relative noise level, to give you a a better understanding of one sound to another.This gives you a better explanation than just trying to involve a complicated mathematical formula.
50 to 55 dBA-Entertainment Industry Quiet -  barely hear the unit operate at 3 feet can have normal conversation next to genset. These genset have special and expensive sound attenuated.
56 to 60 dBA-Ultra quiet/design  - for rental fleets or residential applications. Barely hear the unit operate at 10 feet, normal conversation at 10 feet.
 61 to 63 dBA-Super quiet - Special sound attenuation enclosure normally with air-scoops and dense form. Quiet operation at 21 feet, normal conversation at 10 feet.
64 to 68 dBA residential quiet - well designed enclosure with air-scoops and foam. Quiet but noticeable at 10 feet, normal conversation at 21 feet.
69 to 75 dBA industrial quiet - well designed enclosure with air-scoop and dense form. Noticeable noise level at 10 feet, loud conversation at 21 feet.
dBA Levels and their applications
In average residential application, the dBA levels in the 64 to 68 range are usually acceptable and meet most noise level restrictions if any exist.  Some engines are noisier than other and obviously a smaller generator is typically quieter than an large one. Usually the noise level in diesel generators are handle by enclosure design, air flow, and the quality and type of insulation used. The front air-scoops are designed to remove radiator sound. Special grade muffler systems are used to help reduce the engine noise. 
Most manufacturer can design and work with you to meet any noise level restrictions you might need. A quality manufacturer usually can supply you with a special ultra quiet doosan diesel generators in both switchable stationary, mobile design or stationary for industrial and residential high end applications where sound regulations or zone covenants place restrictions on sound level.

How do transfer switches work and can I install one myself?


A transfer switch are used for safe and convenient operation of diesel generators set for backup power. These transfer switches isolates those circuits using generator power during an outage, and eliminates the risk of back feeding the electrical utility, which can cause injury to utility workers. It also eliminates the need to run extension cords around home or office to operate equipment. A transfer switch allows power to be supplied to the service panel either from the utility or the generator system.
There are four types of transfer switches:
The first one is a manually operated meter connected switches and it is designed for generators supplying 7500 watts or less. These are low cost and simple and inexpensive to install.
Second transfer switch manually operates pre-select panels providing 6 to 10 pre-selected circuits that can be used by thesilent diesel generator for power outages  situation.
The third manually operated service rated (100A, 200A or 400A) NEMA-1 (indoor rated) or NEMA-3R (outdoor rated) UL rated panels for either single or three phase applications.
The fourth transfer switch is a automatic operated service rated panels.
Applications of transfer switches?
For small portable generator system that have light power requirements the use of the meter connecting transfer switches can be cost effective and simple to use. You will need to check with the utility company to make sure they allow the use of this type of transfer switch.  The use of a manually operated pre-select type of panel is also suitable for use with smaller generators. Many of these types of transfer switch will only allow 120v applications.
Service rated manually operated transfer switches allow you to match the size of the service panel so you can power any circuit in the panel subject to the limits of the generator output. These transfer switches allow you to provide power to any breaker in the panel even though you may not be able to use them all at the same time based on your generator size.
An automatic transfer switch or inverter system that has a autostart function is designed to work with the generator autostart system which is usually  a part of the generator controller system. These automatic transfer switches are normally sized to match the service entrance panel amperage size or a special emergency panel created to operate special circuits that are needed during any power outage. The automatic transfer switch operates digitally and also has a motorized breaker system. These automatic transfer switches are activated by a two-wire open or closed low-voltage contact system  and is connected to the autostart function on the silent diesel generators controller.

How Many Generator Choices are There?


The answer is a lot! The process is simple if you break it down, and know what you are going to do with a cummins diesel generator. The first step is to find  out if you need a  generator. If you are looking for your business, asking questions what happen when the electricity goes off in your facility. Do the employees go home?  What do you have to do to start the facility back up after a power outage? Are there machines that need to be cleaned out in order to be restarted or how much material do you waste or scrap because the process wasn't completed in time? How long does it take to get started again and do you know the cost of lost revenue during a outage?
There are many reasons why people use diesel generator set for back up power. Some use it to just keep the computers up, or for retail stores the cash register working. Some businesses use it to keep the telephone up and available for their call center. Most home and businesses use generators to keep their electrically equipment running and to save them money and time during a outage.
The types of generators?
Portable Diesel Generators-These generators are used widespread from recreation use to industrial applications. Because they are portable many large construction site use these generators.
Standby Diesel Generators-These are used to power an entire residence to large businesses. they range in size from 5.5kW-25kW and usually are installed in a permanent location with a fuel source supply to it.
Industrial Diesel Generators- Most large and small industries need power fast when a outage occur. Many fuel sources can take up to two minutes or longer to engage. A industrial diesel generator is the generator of choice because it provides power quickly and is an cost effective source of power. 
Backup Diesel Generators-These generators are used were power failures is not a option. They are used in medical facilities, military, state and federal agencies just to name a few.
Mobile Light Tower Diesel Generators-This generator can light-up any locations and put light precisely where you want it. It can provide light coverage from 5 to 7 acres on the average.
 
Which fuel do you use?
There are four major types of fuel for generators, they are  diesel, propane, gas  and natural gas. Diesel and LP (liquid propane) are the most common. Diesel is probably the most preferred since you can store it unpressurized, unlike LP. There are many regulatory agencies that you must deal with when installing a standby generator. Many of them have air-quality control districts, besides emission requirements they often have restrictions as to how many hours the generator can be run per year. the average is around 200 hours. Before choosing a generator make sure you check with the regulations in your area.
The fire department should be contracted because they will need to issue the fuel permits required to install the needed fuel tanks in some areas.  Standby generators do create some noise so where you place the cummins diesel generators is another consideration. Some building has building codes that you might have to check before installing a generator.

What is the meaning of Wet Stacking?


"Wet Stacking" happen when a diesel engine operates below the rated output level the engine starts over-fuel or "wet stack". Diesel engines are designed to operate with a load and operate more efficiently in the 70 to 80% range of rated output. When a volvo diesel generator operates for a long period of time below 40% it begins to over fuel. This happens because the injection tips begins to carbonize and disrupt the fuel spray pattern.
How to prevent wet stacking?
A automatic load bank is used in commercial generator systems where loads can vary and low output conditions can occur more frequently because of the different load applications. A load bank places a false load on the diesel generator system to keep the diesel engine properly loaded to prevent a wet stacking condition.
For small business or residential application wet stacking can be taken care with the use of an electric heater or other high load appliance to make sure the genset system is not allowed to operate for prolonged periods of time.
How to correct the "wet stacking" if it has occur?
The only way to correct a diesel engine if it has begun to wet stack is to load the engine for a couple of hours to burn off the excess fuel and clean up the engine. Diesel generator sets with electronically controlled engines or advance emission systems are less likely to wet stack. But all diesel engines will wet stack unfortunately, if operated for long periods of time below rated levels. This is the reason it is important to get the proper size and design of volvo diesel generators.

What is the good diesel generator?


Many people have this question, is diesel generator a good investment for my home or office? Well, it really depends. In general, people rely on cummins diesel generator that supply emergency power failure. Thus, it is effective?
 
diesel generator is a combination of a diesel engine with an alternator as a generator for generating electrical energy is not known. These devices have been used for many years. In fact, diesel generators have been used commercially for many years. The primary function of emergency diesel generators is to eliminate the chemical energy of fuel, and then convert it into kinetic energy.
 
What are the advantages of using a diesel generator?
 
Diesel relatively inexpensive compared to conventional gasoline. The low cost means low fuel costs for generating electricity. Virtually all diesel generators consume far less fuel than those that run on gasoline.
 
In any standard diesel fuel is by far the most accessible source of light. This is especially convenient if you have branches in remote areas. This can easily offset your energy needs worldwide. Not only is diesel generators are safe just because they can not sustain extreme weather conditions, and can show an excellent feature for a long period of time. Regular maintenance is not a problem because there are no candles to worry. So make sure to clean and change oil your machine regularly.
 
Another advantage is that there is support for diesel engines. Since this engine has a lot of general local mechanic or technician to repair it in case of problems. And it can be easily replaced parts are well.
 
The cummins diesel generators are versatile. In addition, it can be used to produce electricity, it can also be used for different applications of energy, that the mechanical and electrical energy generated by the generator to perform various functions. You can choose from different types of energy production to achieve the desired effect and the use of diesel generators for commercial electricity, consumers can be provided in a specific geographic location to c
