Liquid-Cooled generators are the best choice for reliable, long-lasting backup power for your home.

Using Cummins expert advanced technology and design, these Liquid-Cooled standby generators withstand extreme heat, cold, and tested to withstand winds up to 180 mph. So you can depend on them to perform through any outage condition.

All residential Cummins Liquid-Cooled generators operate on Liquid Propane (LP) or Natural Gas (NG). Diesel generators are also liquid-cooled but our focus in this section is LP/NG. Be sure to checkout our collection of Diesel Home Generators. NG?LP generators from Cummins are available from 25kW - 150kW in residential voltage. The 1800 RPM engine speeds are very quiet while in operation and best for optimal fuel efficiency compared to engines running at 3600 RPM.

What Is a Liquid-Cooled Generator?

A Liquid-Cooled Generator is known as the most reliable choice for backup power because they use a cooling agent to maintain the systems temperature for optimum performance through harsh environmental conditions that are typical through power outages. Liquid-Cooled generators use either oil or a “coolant” that operates with a radiator, water pump, and hose, delivering the cooling liquid to the engine block, much like an automobile or truck. This "coolant" process maintains the system's temperature, allowing for maximum operation and performance through extreme temperatures, and is more durable than air-cooled generators. 

Cummins Liquid-Cooled generators are designed with robust materials, specialized coatings, and advanced technology, so they also withstand winds up to 180 mph, and avoid common wear and corrosion that other models experience. In addition, Cummins standby generators perform quieter than competing models.
