Everything You Need to Know Before Buying Diesel Generators

What is a Diesel Generator? 

Diesel generators are a kind of electric generator used to generate electric energy with the help of a diesel engine. Diesel generators are beneficial in case of power cuts. In case of a power outage, these generators are used as an emergency power supply. 

Some Kinds of Diesel Generators 

There are various kinds of diesel generators. Different diesel generators have different sizes, purpose, and designs. Before buying a diesel generator, you should have complete knowledge of different types of diesel generators: 

#1. Industrial or Residential: Industrial generators are generally large, and these are used to provide endless power supply. The word “industrial” suggests that these are used in industries where the power demand is high. At the same time, the residential generators are generally smaller in size and are utilized in offices, houses, and shops. They do now produce as much power as a residential generator and are thus perfect for houses and small establishments that don’t require much power. Also, due to the compact size, they can be easily installed. 

#2. Air-cooled or Water-Cooled: In an air-cooled generator, air is used for cooling down the generator while it functions. One the other hand, in water-cooled generators, the generator utilizes water to keep the temperature down. Water cooled generators are costlier since there is an additional system that facilitates the cooling. Also, these require regular maintenance which leads to an increase maintenance cost. 

#3. Power: Before buying diesel generators, it is essential to know the power requirement. The selection of a diesel generator will depend upon how much power is required and whether or not a generator will be able to deliver it efficiently. 

#4. Phase: Another essential factor is the “phase”. Diesel generators are available for single-phase as well as three-phase connections. For this, you will have to identify the type of connection in your house. If you are getting one for an industry that has extensive machines, it will most likely require a three-phase power supply. 

#5. Fuel Consumption: Fuel consumption is one of the essential factors you should keep in mind while buying a diesel generator. You must enquire about the fuel consumption in terms of liters or gallons per hour. This will help you get an idea of the amount you would be spending on fuel. 

#6. Control System and Power Management System: A variety of diesel generators have advanced technology functions such as early warning signals like low fuel, and features like automatic transfer of power to the generators at the time of power cuts. The power management system performs an essential function as it helps in optimizing the consumption of fuel. 

#7. Portability and Size: When buying a diesel generator, you should look for features such as the availability of wheels at the base of the generator which increases its mobility. Another essential thing which you should keep in mind is the size of a diesel generator; the smaller the size of a diesel generator, the better it is as it will not occupy much space. 

#8. Noise: Another essential factor when buying a diesel generator is ‘Noise’. Loud noise from the generator will add to the noise pollution and on prolonged exposure, you may develop severe hearing disorders. The noise absorption feature is available in some diesel generators and helps reduce the noise level. These types of generators are highly popular in the market. 


From the above factors, we can conclude that you should keep every small to big thing in mind when buying a diesel generator, whether it is quality, size, power, phase, or anything else. This will help extract the maximum benefits out of the diesel generators and not having to worry about replacing them anytime soon.
