Proheat Air

Ultra-Quiet Air Heater with Thermostat Control

Proheat Air is the new standard for heavy-duty truck air heaters, quietly delivering constant and reliable heat in cold weather environments. Available in 2 and 4 kW models, its high-efficiency design reduces overall vehicle emissions and engine wear by eliminating the need to idle the engine to heat the sleeper cab. Proheat Air saves fuel costs for fleets and operators while helping drivers comply with local idling restrictions. A digital remote panel provides comprehensive and precise control of Proheat Air from anywhere inside the truck cab.

The Proheat Air truck kit includes a thermostat that makes operation of the heater quick and easy. The thermostat features backlit buttons for fan and power as well as a large rotary knob for easy temperature control.

A surface-mount design means it can be installed inside the cab wherever it’s most convenient.

Cut Operating Costs & Emissions


By installing Proheat Air, fleets and operators can save thousands of dollars each year by eliminating the need to idle the vehicle’s engine as a source of heat for driver comfort. Engine idling puts unnecessary hours on the engine, increasing engine wear and overall vehicle emissions. Prohibiting idling is also quickly becoming the focus of local and federal law makers, as well as a target for local law enforcement.

Proheat Air uses a fraction of the fuel a truck engine uses to idle while still generating a quiet, constant flow of heat that drivers can adjust as desired.
How many hours do your trucks idle for cab comfort heating in a typical year? Since Proheat Air burns 95% less fuel than a truck engine, trucks that idle unnecessarily for hundreds of hours will pay for a Proheat Air in a single winter season.
