Air-Cooled vs. Liquid-Cooled Generators:
What's the Difference?
When the power goes out, you need backup power you can count on.
Benchmark Electric provides backup power solutions from Cummins Power Generation — a world leader with over 100 years of engineering innovation serving hospitals, data centers, airports, and industrial facilities worldwide. That same trusted technology is available to protect your home or business.

Air-Cooled Generators
Great Power, Excellent Value
Air-cooled models come in three sizes — 13kW, 17kW, and 20kW — making them a great fit for most homes. The RS13A covers homes up to 1,200 sq ft, the RS17A up to 1,500 sq ft, and the RS20A up to 2,000 sq ft.
All three include built-in Load Management, so you can get whole-home coverage even on a smaller unit. The system automatically prioritizes high-energy loads — running one air conditioner at a time, for example — so nothing gets overwhelmed.
Standout features include:
- Whisper-quiet operation at just 65 dB(A) — about the volume of a normal conversation
- Reliable cold weather starting down to 0°F standard, or -40°F with an extreme cold weather model
- Wind resistance up to 180 mph
- Wi-Fi connectivity with smartphone alerts so you always know your generator's status
- Made in the USA

Cummins QuietConnect™ Liquid-Cooled NG/LP Generators
Top Performance for High-Demand Needs
For larger homes and businesses with serious power demands, liquid-cooled generators are the premium choice. Available in natural gas or LP configurations up to 150kW and beyond, these units are built to handle anything — intense heat, harsh winters, and hurricane-force winds up to 180 mph.
A liquid-cooled Cummins generator can simultaneously power multiple A/C units, electric heating, pool equipment, sump pumps, and every appliance in your home — all at once, without compromise.

Cummins Diesel Generators
Built to Last
When you need extended runtime and decades of dependable service, diesel is the right choice. Cummins diesel generators range from 20kW to 500kW and are available in residential, commercial, and industrial electrical configurations.
Every residential diesel unit comes standard with double-wall protected fuel storage and an aluminum, sound-attenuated enclosure — built for safety, longevity, and quiet operation in noise-sensitive areas.
