We Offer a Wide Selection of Used Diesel Generators

Single and three-phase diesel generators are commonly used as a backup or standby power source in hospitals and other facilities where a continuous, uninterrupted power supply is essential. This is because, unlike natural gas that is supplied through gas lines that could be disrupted during a catastrophic event, the diesel fuel used to power the generator is stored in tanks. This ensures a steady supply of fuel to the generator will always be on hand.

Another benefit of a diesel generator is that its engine does not require the use of spark plugs or wires, which simplifies preventive maintenance. Finally, a used diesel generator tends to have a longer lifespan than its natural gas counterpart.


You Will Also Find a Large Assortment of Used Natural gas Generators

Natural gas generators offer a number of advantages of their own. Gas burns much cleaner than diesel fuel and does not produce a pungent odor. The fact that natural gas is abundantly available via pipelines eliminates the need to store fuel.

Perhaps the most attractive benefit offered by used natural gas generators is that the cost of the gas is normally cheaper than diesel fuel, although the need for additional maintenance can make diesel gas generators more expensive to operate in the long run.
