The 30XW liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building
owners require optimal performances and maximum quality.
-
Premium full load and part load performance
New twin-rotor screw compressor speci cally designed for HFC-134a equipped with a high-ef ciency motor and a variable
capacity valve that permits exact matching of the cooling capacity to the load.
Flooded multi-pipe evaporator and condenser for increased heat exchange ef ciency. The evaporator has a low pressure
drop-which results in reduced cost of water pump.
Electronic expansion device permitting operation at a lower condensing pressure and improved utilization of the evaporator
heat exchange surface (superheat control).
Economizer system with electronic expansion device for increased cooling capacity (30XW-P).
Absolute reliability
Screw compressors
- Industrial-type screw compressors with oversized bearings and motor cooled by
suction gas.
- All compressor components are easily accessible on site mini-
mizing down-time.
- Protection increased by an electronic board.
Refrigerant circuit
- Two independent refrigerant circuits (from
800 kW upwards); the second one au-
tomatically takes over, if the rst one
develops a fault, maintaining partial
cooling under all circumstances.
Evaporator
- E lec t ron ic paddle-f ree f low
switch. Auto-setting according to
cooler size and uid type.
Auto-adaptive control
- Control algorithm prevents exces-
sive compressor cycling (Carrier
patent).
- Automatic compressor unloading in
case of abnormally high condensing pres-
sure.
Exceptional endurance tests
- Partnerships with specialized laboratories and use of
limit simulation tools ( nite element calculation) for the design
of critical components.
- Transport simulation test in the laboratory on a vibrating table and then on an
endurance circuit.
Environmental care
R134a refrigerant
- Refrigerant of the HFC group with zero ozone
depletion potential.
Leak-tight refrigerant circuit
- Reduction of leaks as no capillary tubes and are
connections are used.
- Veri cation of pressure transducers and tempera-
ture sensors without transferring refrigerant charge.
- Discharge line shut-off valve and liquid line service
valve for simpli ed maintenance.
03
Easy and fast installation
Compact design
- The 30XW units are designed to offer the most compact dimensions on the market.
- With a width of approximately 1 m up to 1500 kW the units can pass through standard door openings and only require minimum oor
space in the plant room.
Simpli ed electrical connections
- Main disconnect switch with high trip capacity.
- Transformer to supply the integrated control circuit (400/24 V).
Simpli ed hydronic connections
- Victaulic connections on the evaporator and condenser.
- Practical reference marks for entering and leaving water connections.
- Possibility to reverse the heat exchanger water inlet and outlet at the factory.
Fast commissioning
- Systematic factory operation test before shipment.
- Quick-test function for step-by-step veri cation of the instruments, expansion devices and compressors.
Pro-Dialog control
Pro-Dialog combines intelligence with operating simplicity. The control con-
stantly monitors all machine parameters and precisely manages the opera-
tion of compressors, electronic expansion devices and of the evaporator
water pump for optimum energy ef ciency.
Energy management
- Internal time schedule clock: controls chiller on/off times and opera
tion at a second set-point.
- Set-point reset based on the return water temperature.
- Master/slave control of two chillers operating in parallel with operating
time equalization and automatic change-over in case of a unit fault.
Ease-of-use
- User interface with large touch screen (120 x 99 mm) for intuitive ac-
cess to the operating parameters. The information is in clear text and
can be displayed in local language (please contact your distributor).
Remote management (standard)
The 30XW is equipped with an RS485 serial port that offers multiple remote
control, monitoring and diagnostic possibilities. Carrier offers a vast choice
of control products, specially designed to control, manage and supervise the
operation of an air conditioning system. Please consult your Carrier repre-
sentative for more information.
The 30XW also communicates with other building manage-ment systems via
optional communication gateways.
A connection terminal allows remote control of the 30XW by wired cable:
- Start/stop: opening of this contact will shut down the unit.
- Dual set-point: closing of this contact activates a second set-point (ex-
ample: unoccupied mode).
- Demand limit: closing of this contact limits the maximum chiller capacity
to a prede ned value.
- Operation indication: this volt-free contact indicates that the chiller is op-
erating (cooling load) or that it is ready to operate (no cooling load).
- Alert indication: this volt-free contact indicates the necessity to carry out
a maintenance operation or the presence of a minor fault.
- Alarm indication: this volt-free contact indicates the presence of a major
fault that has led to the shut-down of one or several refrigerant circuits.
