Dometic Environmental Corp., a business unit of Dometic Corp, has introduced an expanded series of all-electric auxiliary air conditioning systems. The new systems run on 12V power from the truck’s batteries and include a 7,000 or 10,000 Btu split- or self-contained AC system, a DC/AC inverter, a high-capacity alternator and optional shorepower connection. Both sleeper and day cab versions are available.
The patented split-system design features a condensing unit mounted on the outside of the truck and an evaporator/compressor/blower unit installed inside the vehicle with quick-connect refrigerant line sets. Units are pre-charged at the factory with refrigerant fluid to simplify installation.
“Some people are telling us they want to get away from engine-based APUs because they just don’t want another engine to maintain,” said Lou Siegel, sr. vp-marketing and strategic business development for Dometic Environmental. “The installed cost [of the all-electric system] is considerably less than that of an APU-based system and maintenance costs are virtually eliminated. Since no separate diesel engine is required, they are quieter, use no fuel and produce no exhaust emissions.”
For customers who prefer a conventional idle reduction system, the company also offers a full range of self-contained and split air-conditioning systems for use with engine-based APUs.
