QT SERIES
The quiet standard in liquid-cooled
automatic standby power

Generac’s QT Series generators have redefined backup power for larger residential and commercial applications. These models feature automotive grade liquid-cooled engines for proven power and performance.

With outputs ranging from 22 to 150 kW, these QT models feature:

  • Quiet-Test™: All models feature the patented Quiet-Test low-speed exercise mode for quieter weekly self-test.
  • Durable Enclosures:

    • Steel enclosures have a galvanneal paint finish which bonds zinc to steel for superior rust and corrosion protection.
    • Aluminum enclosures are corrosion resistant and ideal for salt air coastal conditions.
  • Continuous Fuel: All models run on LP gas or natural gas, providing continuous fuel and reduced emissions.
  • Stable Output: Clean, consistent power for sensitive electronics. UL Listed.
  • Transfer Switches: Matching transfer switches sold separately. Rated from 100 to 800 Amps. See page 8.
22 KW - 60 KW MODELS Generac 22 - 60 kW Liquid Cooled Generators
Ideal for many large residential and commercial applications. A perfect size for small office buildings, churches, municipal buildings, retail centers, police stations, schools, farms, convenience stores and restaurants.

 

Natural gas is delivered reliably and continuously underground. Spark-ignited engines start more easily than diesel engines in cold climates. Spark-ignited engines start more easily in cold climates. Spark-ignited engines are also quieter in terms of noise, vibration and harshness. Natural gas demand drops significantly during a power outage assuring more than adequate supply. Gaseous fueled engines emit fewer pollutants than other fuels and are more environmentally friendly.
