GUIDE SPECIFICATIONS
TW Series Two Stage Water-to-Water Reverse
Cycle Chillers & Low Temp Boilers
TW025-071 Reverse Cycle Chillers / Low Temperature Boilers
GENERAL
Units shall be Underwriter Laboratories (UL) listed for safety
on all models. Each unit shall be run tested at the factory,
pallet mounted and stretch wrapped. The units shall be
manufactured in an ISO 9001:2000 certified facility, designed
to operate with entering fluid temperatures between 20˚F
(-7˚C) and 120˚F (49˚C) as manufactured by Bosch in Fort
Lauderdale, Florida. Refrigerant shall be R-410A.
CASING & CABINET
The cabinet shall be fabricated from heavy gauge steel
finished with a vinyl coated black cabinet and decorative gold
anodized aluminum front panel for corrosion protection. The
interior shall be insulated with ½" (12.7mm) thick foil faced
glass fiber. All units shall allow sufficient service access to
replace the compressor without unit removal. The compressor
shall be covered with a multi-density sound absorbing blanket
and have a floating base pan to minimize noise transmission.
REFRIGERATION CIRCUITS
All units shall contain a hermetically sealed refrigerant circuit
including a two stage scroll compressor, bidirectional thermal
expansion valve metering device, coaxial style fluid-torefrigerant heat exchangers, refrigerant reversing valve and
service ports. Compressor shall be high efficiency, two stage
scroll type, designed for heat pump duty, quiet operation and
mounted on rubber vibration isolators. Compressor motors
shall be equipped with overload protection. Refrigerant
reversing valves shall be pilot operated sliding piston type
with replaceable encapsulated magnetic coils energized
only during the chiller cycle. The coaxial water-to-refrigerant
heat exchanger shall be constructed of a convoluted copper
(optional cupronickel) inner tube and steel outer tube with a
designed refrigerant working pressure of 600 PSIG (4100kPa)
and a designed water side working pressure of no less than
400 PSIG (2750kPa). Due to their susceptibility to fouling,
brazed plate heat exchangers are not acceptable. The fluidto-refrigerant heat exchangers shall be insulated to prevent
condensation at low fluid temperatures.
Catalog (TW Technical Data Sheet)
ELECTRICAL
Controls and safety devices will be factory wired and mounted
within the unit. Controls shall include comfort alert module,
compressor contactor, 24V transformer, reversing valve coil
and solid state lockout controller (UPM) The UPM controller
shall include the following features: Anti-short cycle time delay,
random start, brown out/surge/power interruption protection,
120 second low pressure switch bypass timer, shutdown on
high or low refrigerant pressure safety switch inputs, shutdown
for the optional freezestat, 24 VAC alarm output for remote
fault indication, unit reset at thermostat or disconnect, ability to
defeat time delays for servicing and automatic intelligent reset.
The UPM shall automatically reset after a safety shut down
and restart the unit, if the cause of the shut down no longer
exists, after the anti-short cycle and random start timers expire.
Should a fault re-occur within 60 minutes after reset, then a
permanent lockout will occur. A light emitting diode (LED) shall
annunciate the following alarms: high refrigerant pressure,
low refrigerant pressure and low water temperature (when
equipped with the optional low water temperature sensor).
The LED will display each fault condition as soon as the fault
occurs. If a permanent lockout occurs, then the fault LED will
display the type of fault until the unit is reset.
Safety devices include a low pressure cutout set a 40 PSIG
(280 kPa) for loss of charge protection (freezestat and/or high
discharge gas temperature sensor are not acceptable) and a
high pressure cutout control set at 600 PSIG (4100 kPa). An
optional energy management relay that allows unit control by
an external source shall be factory installed. A terminal block
with screw terminals shall be provided for control wiring.
PIPING
Water piping connections shall be female pipe thread with a
single set of source and load connections flush mounted to
the unit cabinet.
hEAT RECOvERy PACkAGE
208/230 volt units shall be equipped with an optional factory
installed internal heat recovery kit for domestic hot water
production. This kit shall include a vented, double walled
coaxial water to refrigerant heat exchanger, circuit breaker
protected circulating pump, high water temperature safety
cutoff and a low refrigerant temperature cutout.
