LIEBERT XD CHILLER (XDC) WITH iCOM CONTROLS
STANDARD FEATURES
TANDEM COMPRESSORS - Scroll with a suction gas cooled motor, vibration isolators, thermal overloads, manual reset high-pressure switch and pump
down low-pressure switch.
REFRIGERATION SYSTEM - Dual R-407C refrigeration circuits each including liquid line filter dryers, refrigerant sight glass with moisture indicator,
electronic control valve, adjustable externally equalized expansion valves and liquid line solenoid valves.
HEAT EXCHANGER - Brazed plate design with interwoven circuiting constructed of stainless steel plates, copper brazed.
PUMPS - Centrifugal type. Uses R-134a.
STANDARD CONTROL PROCESSOR - The standard control system is microprocessor-based with an external LCD numerical display to allow
observation of specified settable functions. Normal operating conditions are indicated on the LCD display panel, which is mounted to the unit. The control
system also monitors unit operation and activates an alarm when any of the specified factory preset conditions are exceeded.
CABINET AND FRAME - Custom powder painted steel panels. A hinged control access panel opens to a second front panel, which is a protected
enclosure for all high voltage components. Frame is constructed of 14 gauge heli-arc welded tubular steel and painted using an auto-deposition coating
system.
CANBUS ISOLATOR - Electrically isolates external CANBUS from internal CANBUS. Allows for greater total length of external CANBUS cables.
