The VHG is a variable speed, rotary compressor with a direct DC drive. Our customers choose the VHG compressor because it eliminates the need to convert DC voltage to AC voltage to drive the compressors. VHG is the perfect choice for rooftop AC and rooftop refrigeration units used in recreational vehicles and last-mile delivery. With its light weight, low profile and wide capacity range, the VHG reduces overall power consumption, increases battery life and can fit a wide variety of customer applications.
