General Data

Unit Description

Model CCRC/CIRC units function as the outdoor condenser

unit for appropriately sized split refrigeration systems.

These units operate in conjunction with a matched indoor

compressor/evaporator configuration (Trane models

SCRF, SIRF, SCRG, or SIRG) and provide refrigerant

condensing for these systems down to a normal ambient

temperature of 45°F. Operation to 0°F ambient is possible

with the addition of the optional external mount low

ambient dampers. Refer to the “Low Ambient Damper”

section in this manual.

Model CCRC/CIRC remote air cooled condensers are

dehydrated, leak tested, and charged with a holding

charge of dry nitrogen. Units are tested for proper control

operation before shipment.

The factory provided unit-mounted control panel contains

all required fan cycling controls, compressor interlocks

and 115 V control power transformer. Each unit features

two independent refrigerant circuits with an integral sub-

cooling loop.The slab condenser coils are aluminum fins

bonded to copper tubing. Louvered condenser grills are

for coil protection and are an orderable option. Direct

drive, vertical discharge fans are provided with built-in

current and overload protection. Head pressure control

dampers are available if low ambient operation is

required.

A bag containing the installation/ operation/maintenance

manual, schematics, and other pertaining literature is

provided and located in the control panel. Read all

literature pertaining to unit before installation and

operation. Figure 1 illustrates CCRC/CIRC exterior

component locations
