COMPRESSOR:
One independent 80 hp suction gas cooled Copeland "ROTARY
SCREW" compressor with an EER of 10.7 for years of energy
savings, complete with oil sight glass, cranckcase heater, isolation
valves, two steps of capacity control internal motor overload
protection consisting of winding temperature, phase and wrong
rotation, isolation valves, two steps of capacity control per
chiller, 100% 50% and off.
EVAPORATOR:
Oversized, high efficiency 80 ton stainless steel copper braze
plate evaporator insulated outside with 1/2" armaflex insulation,
with an evaporator inlet water temperature sensor, inlet shut-off
valve mounted to the main header and coupled with grooved-end
pipe fittings to the evaporator.
Evaporator water outlet has a flow
sensor and water temperature sensor, shut-off valve mounted to
the main header and coupled with grooved-end pipe fittings to
the evaporator. Water piping in and out is insulated with 1/2"
armaflex pipe insulation.
An
individual chiller can be removed without interruption to the
main header supply and
return water flows by closing the ball valves and undoing
the grooved-end coupling.
CONDENSER:
Oversized, high efficiency 80 ton stainless steel copper braze
plate condenser with a condenser inlet water temperature sensor,
shut-off valve mounted to the main header and coupled with grooved-end
pipe fittings to the condenser.
Condenser outlet side has a shut-off
valve mounted to the main header and coupled with grooved-end
pipe fittings to the condenser. Condenser leaving water temperature
can be monitored if a second evaporator is not used.
The chiller can operate with dry
cooler water/glycol as low as 70 F entering the condenser, maximizing
the compressor efficiency while maintaining optimum expansion
valve performance. This is the highest energy saving available
to-day.
For water/glycol below 70 F a motorized
condenser water flow valve can be installed and controlled by
an exclusive “chiller control system” maintaining a constant safe
operating head pressure.
An
individual chiller can be removed without interruption to the
main header supply and return water
flows by closing the ball valves and undoing the grooved-end coupling.
CHILLER
CONTROL: Our exclusive
"intelligent chiller control system" surpasses all others
with twelve (12) analogue inputs: eight temperature and four pressure,
two flow sensors, loss of phase and phase reversal, over and
under voltage, phase voltage difference along with four digital
inputs, one for each compressor motor internal sensor, one for
pump interlock or local / remote start.
Our exclusive "control logic"
insures long lasting trouble-free operation with alarm outputs
before failures can occur, automatic compressor sequencing (lead/lag)
to even run time, timed starts to ease inrush current.
Connected to our "master chiller
system control" for staging of 12 chillers with a total 24
steps of capacity control, the “building control system” can monitor
the status of all chillers and change the operating temperature
set point.
With an evaporator flow sensor,
we can prevent freeze-ups before they happen and display the exact
operating capacity in tons of each chiller any time during operation.
Inspection or service is made easy
by displays of all temperature and pressure inputs, evaporator
flow, chiller capacity in tons and super heat of each thermal
expansion valve.
SENSOR
INPUTS:
Our "intelligent chiller control
system" insures both trouble-free operation without false
trips, and also that the chiller operates at the highest efficiency
all the time.
REFRIGERATION
COMPONENTS: Refrigeration thermal expansion valve field
adjustable, filter dryer, liquid line solenoid, liquid line sight
glass with moisture indicator, liquid line shut-off valve and
hot gas by-pass shut-off valve if hot gas used. Some of these
components are not used in our competitors’ equipment.
Refrigeration circuits are piped
with ACR type L copper and fittings, circuit is brazed using nitrogen
to keep internal surfaces clean from scale buildup, evacuated
and charged with freon. Each chiller is run tested and includes
a "run test data sheet" for field comparison at chiller
start-up.
CONTOL
PANEL: NEMA 1 stainless
steel control panel with compressor contactors, compressor circuit
breakers located in bus-duct panel on top of chiller, two control
transformers (one for each compressor) both with primary and secondary
fuses, red emergency stop push button, control board, two line
digital display and data entry key pad.
Our enclosed three phase 900 amp
Bus Bar Duct System is external to the chiller and includes individual
compressor circuit breakers. Our system allows for individual
chillers to be removed from the main bus for service without
shutting down the operating system.
FRAME:
Rugged 12 ga. bolted stainless steel frame with stainless steel
NEMA 1 control panel and bus duct panel, 20 gauge stainless steel
access panels. The base has cutouts for either a fork lift or
pallet truck and uses two of our bolt-on “caster assemblies”.
The casters can be cranked up and down to move the chiller into
place or remove for service.
