Used Generators That Work Like New for Industrial Applications

Used Cummins Diesel Generator for sale..

Select a generator type to cover all of your power needs if your company needs used industrial generators. Since they differ from residential versions, you must select the appropriate generator size for your business. You can find the right generator size by creating a list of all the equipment that the generator will power.

Buying used industrial generators has lots of advantages. Because they are pre-owned, they are substantially less expensive than new generators. Before selling used generators to you, respectable dealers must test and approve them. Choose an industrial generator that may satisfy your company’s needs, as there are several types.

The various types of used industrial generator sets to consider are listed below.

Diesel Generators

Diesel generators are a great choice for industrial applications because of their reliability, long life, and low maintenance costs. Between major maintenance services, a diesel generator running at 1,800 rpm can run for 12,000-30,000 hours. After 6,000-10,000 hours of service, a gas-powered engine of the same size may require extensive service.

Natural Gas Generators

Another less expensive fuel for industrial generators is natural gas. Industrial equipment is supplied by liquefied petroleum gas or propane generators. They’re also long-lasting but expensive when new. The main disadvantage of natural gas generators is that they generate less power than a diesel generator of similar size.

Power Generation Requirements

While generator outputs range from 20 to 2500 kW, some offer single-phase (120 volt) power and others three-phase power (480 volts). Three-phase generators will be required for industrial applications. Generators that provide 120-208 volt or 277-480 volt services are suitable for a variety of applications.

These steps keep repeating themselves until the generator’s full capacity is reached.

Components Of A Generator

You must also understand the components of generators in order to completely comprehend how generators work. A generator may have varied parts depending on the design complexity, but the standard components stay the same.


The generator is driven by the engine, which contains the required mechanical energy to convert into electric energy. Larger engines are used in powerful generators to produce energy.

Engines may run on a variety of fuels, including fuel, natural gas, propane, and diesel, which is the most popular. Natural – gas engines, such as those found in RVs, are smaller, while diesel-powered engines are larger and more powerful.

Some engines are also bi-fuel capable, meaning they can run on both gas and diesel.


The alternator, as stated previously, has a moving and stationary part that work in conjunction to provide electrical output.

The alternator is an important component of the generator because it causes movements between the electric and rotating magnetic fields.

Alternators can be made of plastic or metal, however the latter is more frequently used due to its durability and strength. Plastic, on the other hand, tends to degrade over time, reducing the generator’s efficiency.

A brushless alternator is also a superior choice because it generates cleaner power and requires less maintenance.

Fuel System

Pump, ventilation pipe, connection pipe, water separator, injector, and overflow connection are all parts of a generator’s fuel system.

A fuel tank typically keeps a generator running for six to eight hours.

Although smaller generators have built-in fuel tanks, larger generators, such as those on building sites, require external tanks to be erected.

Voltage Regulator

A voltage regulator converts a little quantity of AC voltage into DC current, which is then sent to the secondary or exciter windings of the stator. The process then continues as described above.

The output voltage decreases significantly as the generator’s load rises. When the voltage regulator detects this, it goes into action and repeats the cycle, pausing only when the generator has reached full capacity.

Cooling System

The interior components of a generator will heat up with time if they are used constantly. This is where the cooling system comes in. Here are a few examples of common cooling systems:

  • Fan or a radiator on the generator
  • Hydrogen
  • Wate

Manufacturers Of The Best Generators To Choose From

With so many industrial diesel generator manufacturers to choose from, deciding on the right brand to supplement electricity can be difficult. To help you focus your search, we’ve compiled a simple list of the finest generator manufacturers. 

Generators are not true power sources in the technical sense. Instead, they should be referred to as power converters. They transform electrical energy into power from fuel sources. Diesel, gasoline, solar energy, hydro energy (water), wind power, natural gas, and propane are the most common generator engines.
