Commercial Diesel Generators

We provide commercial diesel generators for emergency backup power systems for many different business applications, including data centers, office buildings, construction, telecommunications, food and beverage processing, agriculture, laboratories, hospitals, medical facilities and more. At the heart of many of these backup power systems is a standby diesel generator. Diesel generators are available in a wide range of configurations to meet almost any need. Some of the advantages of diesel generators are that they have relatively low maintenance costs, and are considered very rugged and reliable with long service lives.

Global Power Supply has a large selection of new, surplus, and used commercial standby diesel generators from top manufacturers like Caterpillar, Cummins, and MTU. Many of our generators meet EPA Tier 2, 3, and 4 emissions requirements, and can be customized to meet your specific requirements.

multi-vendor solution provider

Diesel power generators, or electrical generator sets, are widely used in industrial and commercial establishments such as data centers, hospitals, and financial and commercial buildings. Diesel generators can be either prime power sources or standby backup power sources.

Diesel fuel is priced slightly higher than gasoline, but has a higher density, allowing more energy to be extracted from diesel as compared to the same volume of gasoline. Diesel generators have the ability to start and assume a load in less than 10 seconds, making them an ideal choice for industrial or commercial primary and back-up power systems.

Global Power Supply has a surplus inventory of diesel generators in a variety of different sizes from all the leading critical power manufacturers in the industry. Browse our current inventory of new and used diesel gensets, or contact us today for custom orders and requests!
