The Ventech LHG (Liquid Heat Generator) is a rapid supplemental heat and idle reduction system.


The LHG provides fast engine and cabin warmup and window defrost while reducing excessive idling – resulting in fuel savings, reduced tailpipe emissions, and reduced wear and tear. The LHG is fully automatic and managed by an Electronic Control Unit (ECU) that engages and disengages the LHG based on coolant temperature, load, and other engine and environmental conditions. If desired, an optional dashboard switch is available.


The LHG is available as part of an installation kit tailored for each specific vehicle application.
