12V AC Compressor

The 12Vdc system substitutes a 12V dc compressor and electronic controller, and as the automatic sleeper control adjusts voltage, the temperature within the cab is maintained. Guchen EAC is working to improve the efficiency of the 12 Vdc system with improvements required in the areas of more efficient A/C operation, better batteries, and improved cab insulation. Either option can be mated with a heater to provide a full, hot/cold weather idle reduction system.
