DESCRIPTION

Packaged air-cooled liquid chiller factory wired, piped, and charged with HFC-134a. Upward

discharge airflow minimizes directional sound and dissipates heat away from surrounding areas.

FEATURES

Cooler is mechanically cleanable ‘‘flooded’’ shell-and-tube type
with removable heads. It is tested and stamped in accordance
with ASME Code for a refrigerant working side pressure of
220 psig (1517 kPa) and a maximum fluid side pressure of
300 psig (2068 kPa) (250 psig [1724 kPa] in Canada) and is
insulated with

Cooler can be equipped with electric heater to help protect against
cooler freeze-up (use of inhibited glycol anti-freeze recommended
for freeze protection).

Compressor is semi-hermetic twin screw design with refrigerant
gas cooled motor and integral oil filter and discharge gas muffler.

Complete thermal and electrical protection is provided.
Air-cooled condenser is constructed of fins mechanically bonded

to seamless copper tubes. Coils are leak and pressure tested at
450 psig (3103 kPa).

Condenser fans are direct driven 11-blade, shrouded axial type,
statically and dynamically balanced, discharging air vertically
upward, protected by coated steel wire safety guards.

3

⁄4-in. (19 mm) closed-cell polyvinyl chloride foam.

Condenser fan motors are totally enclosed 3-phase with perma­nently lubricated bearings and Class F insulation (except speed
control motors).

Each refrigerant circuit includes oil separator, high side pressure
relief device, liquid and discharge line shutoff valve, filter drier,
moisture indicating sight glass, expansion/level control device.

Microprocessor control includes keypad with diagnostic display
displaying set points, time, system status (including temperatures,
pressures and % loading) and the alarm conditions.

Automatic compressor lead/lag.
Capacity control based on leaving chilled water temperature with

return water temperature sensing.
7-Day time scheduling of pump(s) and chiller.
60-Hz Models: 080, 090, 106, 115, 125, 136, 151, 161, 176, 206,

226, 251, and 265.

50-Hz Models: 080, 090, 105, 106, 115, 125, 136, 150, 160, 161,

175, 205, 225, 226, 250, and 265.
