DC Power Solutions describes its DC Top-Cool air conditioner as the most technologically advanced 12- and 24-volt dc-powered air conditioner for vehicles. The roof-mount units, engineered to provide cooling from 6,000 BTU/hr up to 12,000 BTU/hr, utilizes the starting or auxiliary batteries to power the air conditioner without running the engine. The unit is equipped with a battery monitor and control that prevents discharging below the voltage required to start the engine, according to the company.

The DC Top-Cool — designed to eliminate hot weather idling, providing significant savings in fuel and maintenance costs and engine wear — also can be used for cooling while driving, which the company says reduces the engine load and provides fuel consumption savings. The self-contained unit can be installed in about two hours and can be transferred from one vehicle to another with minor modifications, according to DC Power. The low-profile units, which the company says are manufactured in North America in an ISO:9001-registered facility, use R134A coolant.
