Diesel Generators

Powerful Performance Delivered: Diesel Generators

Diesel-fueled generators are specified because they deliver results when and where needed. They are a traditional choice for high kW applications, as well as for facilities where code requirements (NEC 700 and NFPA 110) call for on-site fuel storage, such as hospitals and emergency response centers.  

The all-power diesel engines we provide are easy to maintain, tolerate dirty fuel, and provide incredible endurance in the harshest environments. Diesel generators also provide the response and longevity required for many applications. Many people look for "cheap" diesel generators, but the right kilowatt fit is more important than initial cost.They are also EPA-compliant from the Generac factory.
