Quiet Natural Gas & Liquid Propane Generators - QT Series

These compact, powerful gensets are ideal for a broad range of enterprises, including restaurants, convenience stores, supermarkets, banks, fitness centers, hotels, and retail outlets.

All QT models are available with two fuel choices — natural gas or liquid propane (LP) vapor. Kilowatt ratings are based on LP fuel (power output may be slightly less with natural gas):

  •  20kW
  •  70kW
  •  25kW
  •  80kW
  •  35kW
  •  100kW
  •  45kW
  •  130kW
  •  60kW
  •  150kW

QT Series natural gas / propane generators are a reliable, cost-effective backup power solution for commercial establishments and small businesses. There are over a dozen models to choose from, ranging in output from 15 to 150 kilowatts. These compact, powerful natural gas / propane generator systems are ideal for a broad range of enterprises, including restaurants, convenience stores, supermarkets, banks, fitness centers, hotels, and retail outlets.

Quieter by Design

Generac’s new Quiet-Test™ feature, from which the QT Series natural gas / propane generator system takes its name, is a breakthrough in sound reduction.  With Quiet-Test™, the natural gas / propane generator automatically runs at reduced engine speed when utility power is present, making the genset exceptionally quiet during its weekly self-test and exercise cycle.  QT Series products are environmentally friendly, surprisingly quiet, and amazingly affordable. The QT Series natural gas / propane generators operate on either natural gas or liquid propane (LP) vapor. With these gaseous-fueled products, fuel storage, spillage, spoilage and odor concerns are absent.  The cleaner combustion of natural gas and quieter engine operation also minimize environmental concerns.

All QT natural gas / propane generator models feature sound attenuated enclosures to ensure quiet operation under full load. Interior cooling fans and air passageways are designed for maximum cooling effectiveness and minimal noise.  This patent pending feature is not available from any other manufacturer.

Modular Power System Models — 200 to 1500 kW

For greater power requirements, two QT Series models (100 and 150 kW) are available with optional onboard paralleling capabilities as part of Generac's Modular Power System. This allows the easy combination of multiple units to satisfy higher kilowatt needs without expensive paralleling switchgear.

Amazingly Affordable

Best of all, QT Series natural gas / propane generators are surprisingly affordable. They're designed and engineered for maximum value, making them ideal for businesses that previously regarded standby generators as too costly.  Having standby power allows a business to keep operating whenever utility power is lost. This means a protected revenue stream and avoidance of expensive losses — so a QT generator might actually pay for itself during the first extended outage. Investing in a QT Series genset is a wise business decision.
