The AHG1000

The AHG1000 is a robust, weather-tight, vehicle-mounted auxiliary power and heating system specifically designed for unattended operation in extreme cold weather conditions, just like its big brothers, the AHG2000 & 3000.


All Ventech AHGs provide circulating heated coolant and electrical power and operate independently of the vehicle's engine to keep your vehicle's utilities fully operational 24/7. This enables the main engine to be shut down, significantly reducing main engine idling, fuel costs and tailpipe emissions.

The AHG1000 is equipped with the LHG Liquid Heat Generator from Ventech, providing extreme heating and electrical charging capabilities in the most demanding applications.

The AGH1000 is powered by the durable and reliable Kubota Super Mini 2-cylinder engine, using field-proven technology to reduce fuel consumption and weight. Budget-wise but full-featured, the AHG1000 is also equipped with a digital touchscreen display and control panel for operation from within the cab.

The AHG1000 produces 12v electrical power to keep the vehicle's batteries charged and provide for required electrical demands. It also produces an almost instantaneous flow of heated coolant to the vehicle's main engine, and other onboard services: up to 80,000 BTU’s (~24kW) of heated coolant without flame or electrical draw; more heat energy than any other APU on the market.
