DESCRIPTION
These units are completely assembled, piped, wired, charged
and tested at the factory and are shipped ready for immediate
installation. Only the power supply wiring, the thermostat wir
ing, the condenser water piping, the condensate drain piping
and the ductwork are required to complete the installation.
Units include a one-year limited warranty on all replacement
parts and a five-year limited warranty on each compressor.
APPLICATION FLEXIBILITY
These ìcooling onlyî units can be applied with:
1. Cooling towers.
2. Well or surface water providing the temperature and the GPM of the water meet the application limitations of the unit.
3. Brackish or salt water and a secondary heat exchanger.
They can be installed:
1. Within the conditioned space as ìfree standingî units
without any ductwork. Supply air plenum and return air
grille accessories are available for these freestanding
applications.
2. In an equipment room with both supply and return air ductwork
charge are provided with the unit, for field installation. Duct
flange on CU240 evaporator return is incorporated into the fil
ter frame.
REFRIGERATION CIRCUITS
-
All models utilize "Scroll" type hermetic compressors. Compressors are mounted on rubber isolators to minimize vibration transmission. Internal overload protection is provided.
External high pressure and low pressure cutout switches are
included in each compressor control circuit. The 5 ton units
have a single refrigeration circuit. The 8 -20 ton units feature
two independent refrigeration circuits. Each refrigeration cir
cuit includes an adjustable thermal expansion valve (with
external equalizer), liquid line filter drier, sight glass/moisture
indicator, and service gauge ports.
The evaporator coils are constructed of internally enhanced
copper tubes mechanically bonded to rippled aluminum plate
fins. The evaporator coil is employed in a draw-through con
figuration, and features inter-laced circuiting. Large evaporator coil face area minimizes potential water blow-off.
The high-efficiency tube-in-tube condensers feature a convoluted inner tube design for optimum performance. Standard
models feature a copper inner tube surrounded by a steel
outer tube, and carry a 400 psig working pressure rating.
INDOOR FANS
-
-
-
GENERAL
Horizontal (CH) units are designed for suspended mounting.
HWC models are shipped with ëstraight-throughí evaporator
fan discharge as standard. Airflow orientation is field convert
ible to side discharge. Vertical (CU) units are designed for
free-standing floor mounting. All units are completely factory
wired and pre-piped. Water supply, water outlet, and conden
sate drain connections are via female pipe thread fittings.
All models 5 -25 tons ship as factory-charged unitized packages. The 5 -15 ton units may be field split between the evaporator /compressor section and the upper blower section;
installation is possible through standard height doorways and
elevators. All packages are designed for free-standing floor
mounting. All models are shipped with vertical evaporator fan
discharge as standard. Units are completely factory wired
and piped. Dual circuit models feature internally manifolded
condensers.
CABINET
All cabinets are completely constructed of 18 Ga. corrosion
resistant "Galvalume" coated steel. The entire unit interior
(both evaporator and condensing section) is insulated with
1/2" thick, 2 lbs. density insulation. Service panels are
equipped with lifting handles for ease of removal and han
dling. Duct flanges for return air intake and evaporator dis-
-
Forward curved, double inlet and double width centrifugal
blowers are used for evaporator air movement. Large diame
ter wheels are employed to provide required airflow perfor-
-
mance at minimum rpm and noise levels. Blower wheels are
fabricated of galvanized steel. Blowers employ solid steel
shafts, supported in permanently lubricated ball bearings. All
blowers are belt driven. Variable-pitch motor sheaves allow
for field adjustment of blower rpm.
ELECTRICAL/CONTROLS
All units are completely factory wired with all necessary controls. Manual reset protection is provided on evaporator
blower motors. A manual reset circuit is also provided on
each compressor control circuit in the event of high/low pres
sure cutout. A 24 volt control circuit, with oversize transformer, is provided for field connection. Units are designed to
operate with conventional thermostat control interface.
FILTERS
All models are shipped with 2 inch thick medium-efficiency
throwaway filters factory installed. Filters are accessible from
either front or right side on 5-15 ton models. The CU240 filter
rack is external to the cabinet (shipped loose).
