DESCRIPTION
Carrier's 50XJ Omnizone™ units are self-contained water-cooled indoor vertical packaged cooling units. Units are designed for
use in variable volume (VAV) applications. Units are completely factory wired, piped and charged, ready for installation. Units are
vertical air discharge or horizontal with optional acoustical plenum with open rear air return. 50XJ units consist of direct expansion
evaporator coil, compressors, water-cooled cleanable condensers, single belt drive evaporator fan with VFD controlled motor and
complete microprocessor control system. Optional water or air side economizers and hot water or steam heating may also be added.
These fully painted vertical package units offer flexible economical air conditioning for today's office environment.
FEATURES
Heavy gage structural frame with base rail and lifting lugs.
Four independent circuits with scroll compressor on vibration mounts in acoustically lined compressor compartment.
Multiple compressor selections for each fan size to allow matching load while
maintaining optimum part load performance.
Each compressor with mechanically cleanable shell and tube condenser rated
for 150 psi water side working pressure.
Evaporator coils are 6-row 12-fin per inch aluminum plate fins mechanically
bonded to copper tubes. Coils are fully intertwined full face active for best
humidity control.
Single fan, double width inlet, double outlet centrifugal forward curve fans, statically and dynamically balanced mounted on a fully spring isolated mounting
frame with 2-in. deflection spring isolators and flexible fan discharge collar.
Bearings are L-50 life at 200,000 hours with grease connection.
Three-phase evaporator-fan motor compatible with use on variable frequency
drive with thermal overload protection.
Factory-mounted Variable Frequency Drive (VFD) sized to handle full motor
operating current at full load operation. Provide with duct static sensor.
Full double wall construction in the evaporator section. Microprocessor control
system with unit-mounted display to control unit as stand alone, CCN or network operation.
Unit control panel with Off/local/remote switch, alarm indicator lights, VFD
display and unit interface panel.
Baked enamel painted cabinet will meet 500-hr salt spray requirements.
High and low pressure switches and frost protection on each circuit.
Filter drier, moisture indicator/sight glass and adjustable thermostatic expansion
valves (TXV) on each circuit mounted outside the airstream.
Stainless steel sloped condensate pan with internal trap.
Single point electrical connections and piping connections.
Rear access filter frame for 2-in. or 4-in. disposable type filters.
High discharge static pressure control standard.
Dirty filter switch provide as standard.
All units are ETL and ETL, Canada listed and rated in accordance with
ARI 360.
Standard one-year product warranty.
