Mechanical
Specifications
General
Factory-assembled and wired air cooled
condensing unit. The unit frame is
constructed of 14 gauge welded
galvanized steel. Panels and access
doors are 14 or 16 gauge galvanized
steel. Unit surface is phosphatized and
finished with Trane Slate Gray air-dry
paint. This paint finish exceeds ASTM-
B117 500 hour continuous salt spray test.
The unit coils are protected with steel
louvered panels. These panels add
strength to the cabinet and an
aesthetically pleasing appearance to the
unit.
Refrigeration Circuits and Control
The 20 to 30 ton units are single circuit.
The 40 to 120 ton units are dual circuited.
All the necessary controls to run the unit
fans are provided. The control panel
contains fan motor contactors, terminal
point connection for compressor
interlock and 115 volt control power
transformer. Standard units will operate
from 40 to 115 F. All units shipped with
factory installed liquid line service
valves.
Condenser Coils and Fans
Condenser coils have configurated
aluminum fins mechanically bonded to
copper tubing with integral subcooler.
The coils are underwater burst/leak
tested at 450 psi. Direct
drive condenser fan motors have
permanently lubricated ball bearings
and thermal overload protection.
Low Ambient Operation
Standard ambient control allows
operation down to 40 F with cycling of
condenser fans. Optional low ambient
allows operation down to 0 F with
external damper assembly for head
pressure control. Refer to Options
section for details.
Options
Low Ambient Control
Low ambient allows operation down to
0 F through the use of fan cycling and
head pressure control dampers. The
control consists of a heavy gauge
damper assembly, R-22 operator, tubing
and grommet. All components are
factory-mounted for both production
and Packed Stock Plus units. Low
ambient control must be ordered when
the air-cooled condenser is matched
with a CCKC heat recovery chiller.
Copper Finned Condenser Coil
Copper fins are mechanically bonded to
copper tubes for use in corrosive
atmospheres. Nominal unit capacity
remains the same.
Spring Isolation Package
Spring isolators reduce transmission of
noise and vibration to building structure,
equipment, and adjacent spaces.
Isolators consist of a cast, spring loaded,
telescoping housing as the isolation
medium. Mountings include built-in
leveling bolts, resilient inserts that act as
centering guides, and ribbed neoprene
acoustical pads bonded to the bottom of
the isolator. The kit includes instructions
for field installation.
Neoprene-in-shear Isolation Package
Neoprene isolators reduce transmission
of noise and vibration to building
structure, equipment, and adjacent
spaces. Isolators have a steel plate and
base completely imbedded in neoprene.
Mountings have a 1/4-inch deflection.
The kit includes instructions for field
installation. Available on 20 to 60-ton
units only.
