DOMETIC ELECTRIC HVAC

Dometic Environmental has introduced an expanded series of all-electric auxiliary air conditioning solutions that run on 12-volt power from the trucks’ batteries. The new all-electric HVAC systems are designed to provide clean, quiet and cost-effective cooling and heating without the need for a separate diesel auxiliary power unit (APU).

The all-electric systems meet the most stringent clean-air requirements, the company says, and without a separate diesel engine, they’re much quieter while using no fuel and producing no exhaust emissions. The installed cost is claimed to be “considerably less” than that of an APU-based system, and maintenance costs are “virtually eliminated.”

The Dometic all-electric package includes a 7000 or 10,000 BTU split or self-contained air conditioning system, a DC-AC inverter, a high-capacity alternator and optional shore power pass-through. The inverter converts the 12-volt battery output into 120-volt AC power to drive the air conditioner. The alternator, which replaces the existing engine-mounted alternator, keeps the batteries fully charged whenever the truck is running. The optional shore power connection can recharge the batteries and run the air conditioner whenever an outside AC hookup is available.

Dometic’s patented split-system design consists of a condenser/fan unit mounted outside the truck and a
compact evaporator/compressor/blower unit inside the vehicle, with quick-connect refrigerant linesets. The two
units are both factory precharged with refrigerant, so that the entire system is automatically charged to the
correct pressure when the linesets are connected.

The Dometic air conditioners can provide built-in electric heat, but can also be integrated with fuel-fired heaters
for supplemental heat as needed.
