Bergstrom Inc. has developed a new battery-powered air conditioning system, designed specifically for day cabs. The NITE® Day Cab No-Idle System was developed in response to growing demand for solutions to reduce idling in the day cab industry, as well as increasing Federal, State and local regulations against truck idling. The NITE Day Cab No-Idle System utilizes one or two deep-cycle absorbed glass mat (AGM) batteries to power the air conditioning system. This keeps the driver cool when the truck's engine is turned off. To assure there is sufficient battery power to start the truck, the starting batteries are protected from discharge by a separator. The system uses the same technology as Bergstrom's popular NITE Plus unit, but is installed as a split system. The compressor and evaporator are installed between the truck's seats, and the condenser is mounted remotely to the exterior of the cab.
