22kW Generator

22kW Generator

A 22kW Generator can power a large home or small business. Power management allows 22kW generators to run heavy loads like multiple central air conditioners and water heaters. Generac builds an air-cooled Guardian 22kW Generator and a liquid-cooled 22kW Protector Gas.

A world-wide leader in the power industry, Cummins builds the Quiet Connect liquid-cooled 22kW Generator.

The 22kW Standby Generators run on natural gas and propane. A Cummins or Generac 22kW standby generator can run on either fuel—the installer selects the fuel during installation. Natural gas supplied by a utility allows the generator to run for weeks. A correctly sized on-site propane tank provides fuel for a week or longer. Natural gas installations are the most common with wide availability in most towns and cities.

24kW Generator

The most powerful air-cooled standby on the market is the Generac Guardian 24kW Generator. Certified for 18-inch to building installation, it fits into small backyards or commercial spaces where the larger liquid-cooled generators take up too much room. Affordable, air-cooled standby power, the Generac 24kW Generator powers large homes and small businesses with power management options that handle up to 4 air conditioners and 8 additional prioritized loads.

For hot climates or any installation requiring exceptional reliability, choose a liquid-cooled 24kW Generator from Kohler or Generac. The Kohler 24kW Generator runs quiet—as low as 61 dBA—and produces 24kW using LP propane or 21kW running natural gas. Hydraulic lifters eliminate long break-in periods. Premium power quality with exceptional voltage and frequency regulation and low harmonic distortion. The Kohler 24kW Generator boasts exceptional peak motor starting with 37kVA at 240 Volts.

22kW Standby Generator

Manufacturers make both air cooled and liquid cooled 22kW generator models. Air-Cooled units use a fan to blow air over the engine and the alternator to keep them cool. The cooling system works well in moderately warm temperatures. The smaller engine and less complex cooling system reduce maintenance costs and operating fuel expense.

Air-cooled 22kW standby generator models are popular for residential installations. They provide plenty of power for an entire home. Power management allows a smaller generator to supply a large home by balancing power use across heavy loads.

Liquid-Cooled models use a cooling system like an automobile. A pump circulates a coolant through the engine and radiator. A fan blows air through the radiator to remove heat. The liquid-cooled system keeps the 22kW generator engine and alternator cool even in desert climates where temperatures reach triple digits.

22kW Generator Systems

When a power outage hits, a 24kW or 22kW standby generator starts and runs the moment power is lost. An automatic system, the generator and automatic transfer switch (ATS) work together to restore power in a few seconds. The generator starts when it detects an outage, then signals the transfer switch to shift the load from utility power to standby generator power. The automatic transfer switch disconnects the utility first, then connects the generator.

A complete 24kW or 22kW generator system includes the generator, an automatic transfer switch, and power management modules for heavy loads. Air conditioners operate on a relay and don’t require an additional management module for operation if the ATS has built-in air conditioner capability. Norwall sells air-cooled bundles that include both the generator and the ATS. Transfer switches for liquid-cooled generators are sold separately.

Power management modules control 240-volt appliances including electric water heaters, well pumps, electric ranges, and other heavy loads.

A whole-house system includes a service-rated automatic transfer switch that installs between the utility meter and the main panel. When the ATS selects the 24kW or 22kW generator, all circuits have power as if it came from the utility. Power management can disable managed appliances if they would overload the generator.

The power management system allows a smaller, fuel efficient and less costly standby generator to supply an entire house with electrical power during an outage.
