4 APC NetworkAIR CM Series: Overview

Water cooled. Unit used with a cooling tower or other source of water.

Field refrigeration piping is eliminated by a factory sealed and tested system.

Water piping to and from the unit is required.

Glycol-cooled. Unit used with a drycooler. The need for field refrigeration

piping is eliminated by a factory sealed and tested system. The glycol piping

is sealed, eliminating costly water treatment often encountered with open

cooling towers.

Remote-condensing. Unit used with a remote air-cooled condensing unit

which includes the compressor(s). This allows key maintenance procedures

to be located outside the critical environment helping eliminate access by

maintenance personnel in high security areas. Available in air, water, and

glycol models.

Chilled water. Unit used with building chillers to provide economical and

reliable control. These models often provide the optimum solution for large

cooling needs due to ease of installation and the elimination of multiple

refrigeration components. They can adapt to existing buildings serviced by

chillers with sufficient capacity.

Pre-cool. Unit designed to reduce operating costs during mid to low ambient

temperatures by integrating an economizer coil into the glycol-cooled unit to

utilize the outdoor ambient cooled glycol assist or completely cool the indoor

air. Available in 2–5 ton models.

Serviceability The CM Series has removable panels allowing full service access to all

components without having to remove the unit from the ceiling.

Humidity control Humidity is managed through a self-contained steam canister humidifier for

maximum efficiency and ease of maintenance. The pure steam canister

maintains consistent capacity output, and requires very little or no scheduled

maintenance.

Compliance The CM Series has received agency approvals by ETL and MEA #256-94-E

(1.5, 2, 3, 5 ton), #177-01-E (1, 4 ton)

. Electrical systems comply with NEC

and UL 1995 standards.
