Ventech has been supplying Puritan Automation with its heavy duty arctic 600 Series LHG. Puritan Automation has incorporated the LHG technology into an exciting alternative to the traditional auxiliary power unit. Puritan’s solution to the APU is its Arctic Heat Generator, or more simply, the AHG. This system is integrated into trucks operating in cold weather environments. While traditional APUs simply provide basic electrical needs to the truck and maintain a comfortable environment for the cabin, the AHG does the same, plus adds enormous benefit for the truck engine. As the heating system is integrated into the truck’s coolant system, the AHG maintains an optimal level of heat to the engine. This not only helps with engine starts, but equally importantly, preserves engine life.
