8 APC NetworkAIR CM Series: Standard Features

Electric reheat The electrical resistance heater is sized to offset the sensible cooling capacity

in the dehumidification mode. The reheat elements are low watt density

finned tubular on the 1 to 1.5 ton systems. Open coil resistance type are used

on the 2 to 5 ton systems. Reheat elements are electrically and thermally

protected.

Refrigeration system

and compressor

The refrigeration system consists of a single hermetic compressor, externally-

equalized expansion valve, filter-dryer, high pressure switch, refrigerant sight

glass, and moisture indicator.

Cooling coil The CM utilizes a one piece evaporator coil constructed of seamless copper

tubes and aluminum fins, mounted in a stainless steel drain pan.

Condenser The 1 to 3 ton systems utilize a coaxial tube in tube, convoluted multi-lead

inner tube design. The 4 and 5 ton models employ a brazed plate condenser

that uses the latest heat transfer technology. Type 316L stainless plates are

brazed together in a vacuum furnace and comply with ASME pressure vessel

code.

Air filter The filtration of conditioned air is extremely vital to maintain the clean,

particle-free environment required by the electrical equipment. The CM

series uses 30% efficient 1" deep filters, with full depth filter pleats. Filters

are easily replaced on all CM model configurations.

Water-regulating

valves

The water- and glycol-cooled systems maintain proper performance by

sensing refrigerant discharge pressure and regulating the amount of water or

glycol supplied to the condenser. Two-way and three-way valves are

available. The standard valve pressure rating is 150 psi (1030 kPa).
