Air Cooled (DX)
Air cooled systems are not pre-charged from the
factory and require field refrigerant piping. Each
installation requires an engineered piping solution.
APC strongly recommends installation by a highly
qualified refrigeration contractor to avoid improper
elevation and long piping runs. The Air Cooled
system uses refrigerant as the heat transfer medium.
Room air recirculates through the InRoom unit
which houses the evaporator coil, scroll compressor,
and refrigeration system. A remotely mounted air-
cooled condenser is connected to the unit. The
sealed refrigeration circuit will absorb the room heat
load and reject it to the outside atmosphere.

The MultiCool System is a combination
of the Air Cooled System and the
Chilled Water System and contains two
separate cooling coils. The controller
microprocessor manages the MultiCool
System to allow the air cooled by the Air
Cooled system to operate as a standby
system to the Chilled Water (CW)
system or vice versa, giving the added
security of back-up cooling to the
computer room.
