Diesel Generators: Everything you need to know before buying one
A diesel generator is a useful appliance that can be a backup or main power for continuous supply of electricity. It is a machine that converts diesel into energy through combustion. Diesel is more efficient than gasoline because it produces more power.
How Diesel Generator Works
The generator converts chemical energy into electrical energy through the engine and alternator. It is important to note that are four main categories of diesel generator depending on the need or use. Each type has its load factor and hours.
Emergency Standby (ESP) and Limited Time Power (LTP) are used for standby purposes, while Continous (COP) and Prime Rated Power (PRP) can be used as the main source of power.
A standby generator has a transfer switch that functions as a disconnector from the main power supply. This switch protects from damage and fire hazard for both the generator and the people working on it.
The generator starts with air being blown until it is compressed then diesel fuel is dispense. Once these two elements are being processed, they generate heat that will trigger the fuel to combust.
Once it is up and running, it will able to generate the electrical power needed. A simple analysis showed how diesel generator can save on energy cost as much as 30% (1)
A diesel generator can work for long periods making it perfect for areas with no electricity or poor access to the power grid. However, maintenance is essential to keep the generator working well.
Types of Generator
- Industrial and Residential
An industrial generator is able to provide a large amount of power for a long period. They are designed to cater to industrial needs. On the other hand, Residential comes in smaller size such as the portable diesel generator and intended to meet the power need of a house, shops, or offices.
- Water/Air Cooled
This refers to the cooling function of a generator. Air-cooled has an air intake system to help cool the generator while water-cooled has a specific and separate system and often needs additional maintenance care.
What to Consider Before Buying a Diesel Generator
- Power Capacity
You would want to buy a diesel power generator that will generate enough power for your needs, whether it is a home, office, or commercial space. You need to know the amount of power requires to run your home or commercial space.
Diesel generators have various power ranges that will fit any type of need. For homes or small offices, a 3kVa generator is sufficient to power the air-conditioner, computer, and fans. Meanwhile, a 2000 kVa is suitable for big industries. It is important to check for the power before getting one.
- Fuel capacity
If you are in an area where power shortage is common, consider the generator’s fuel capacity. There are generators available on the market that fuel-efficient as they can adjust their rotations per minute depending on the load demand.
Nowadays, diesel generator for sale produce cleaner emissions, but you can still sense that smoky exhaust with a strong gas smell when being used. This can be harmful to both humans and animals when placed indoors. Others choose to place their set outside with weatherproof for proper ventilation. If you choose to put it indoors, make sure to have a separate generator room.
- Noise – Are diesel generators noisy?
Generators are noisy, but diesel ones are particularly loud. It can cause headaches and damage to the eardrums when exposed for a long period. The noise can be managed by installing a soundproof enclosure. You can also ask the help of a consultant to create a room that is safe for generator use.
Can a generator run for 24 hours?
A generator can run for 24 hours as long as there is enough fuel. However, portable ones or the standby type are not encouraged for long use. For safety, opt for the industrial type that can cater to longer hours or days.
How efficient is a diesel generator?
Diesel generator has been used for more than a century because of the combustion method. This method leads to reduced fuel consumption. A diesel generator is efficient because compressed air creates combustion without any spark ignition.
Diesel Genset also has a high energy density and high compression ratio, giving it more power than the typical gas. It is also easier to maintain with low maintenance costs. Since it has a no-spark ignition system, it still can function well in colder climates.
Buying the right diesel generator will improve your commercial or residential electrical needs. Getting the necessary information such as the power needs, availability of a safe generator room or enclosure, as well as the cost, availability, and accessibility of diesel fuel in your area are factors to consider. The many advantages of diesel genset make it a top choice among users around the world.
