Enviro-Fleet on Friday, March 31, highlighted its line of aftermarket HVAC systems for sleeper cabs available in under-bunk, rooftop and back wall options. The self-sealed units eliminate refrigerant lines and require only external electrical power.
Two back wall models range from 9,400 Btu to 1,300 Btu AC and 8,000 Btu heat. Two rooftop models have cooling capacities of 13,500 Btu and 15,000 Btu and an integrated 5,600 Btu heater. The under-bunk model provides 14,000 Btu AC and 8,000 Btu heat. A second under-bunk unit with 9,400 Btu AC is under development. Weights range from 80 to 140 pounds.
All models use onboard generators and shorepower, and the under-bunk unit and the smaller capacity back wall units can be powered by four or six AGM batteries.
