DC Power Solutions says its roof-mounted 12- and 24-volt DC Flex-Cool split unit is the latest addition to their
range of DC-powered air conditioners. These split units provide cooling from 5800 up to 11,500 BTU/hr,
without idling an engine. The Flex-Cool technology uses the truck’s starting or auxiliary batteries to power the
air conditioner, employing a battery monitor and control to prevent discharging below the voltage required to
start the engine.

The air conditioner is said to provide significant savings in fuel and maintenance costs, along with reductions in
engine wear. The DC Flex-Cool can also be used for cooling while driving, reducing the engine load and providing further fuel savings.

The flexibility of this split unit enables installation with a variety of mounting options: the condenser can be
mounted anywhere on the outside of the sleeper cab, while the evaporator unit with temperature controls can be mounted virtually anywhere inside the cab. And it can be easily transferred from one vehicle to another with
minor modifications.

The DC Flex-Cool and the DC Top-Cool rooftop units are manufactured in North America.
