Enviro-Fleet aftermarket HVAC systems for sleeper cabs are 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 A/C 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. Weights range from 80 pounds 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 absorbed glass mat batteries.
