AquaForce®
30XW-G

Performance Features

• Non-ozone depleting chlorine-free refrigerant HFC-134a
• AHRI certified maximum full load efficiency up to 0.573 ikW/Ton and IPLV to 0.430 ikW/Ton
• New twin-rotor screw compressor equipped with a high-efficiency motor
• Variable capacity valve that permits exact matching of the cooling capacity to the load.
• Flooded multi-pipe evaporator and condenser for increased heat exchange efficiency.
• Electronic expansion device permitting operation at a lower condensing pressure and improved utilization of the evaporator heat exchange surface (superheat control)
• Entering-fluid temperature continuously monitored to detect flow or load changes
• Wye-delta starter
• Compatible with Carrier Comfort Network® (CCN) communication link
• Certified in accordance with AHRI Standard 550/590

Reliability Features

• Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
• Dual independent refrigeration circuits (from 900 kW upwards).
• Reduced number of moving parts, with compressor rotors directly driven by the motor, to lower the failure rate
• Low voltage control circuits
• Short cycle protection

Maintenance Features

• Hermetic twin screw compressors
• Mechanically cleanable condenser and evaporator
• Alarm contacts
• Filter drier
• Accessible service information including suction and discharge pressure and temperature using Navigator™ display module (factory-installed option or field-installed accessory)
• Discharge and liquid line shutoff valves (factory-installed option)
• ON/OFF control switch

Installation Features

• With a relatively small width, only require minimum floor space in the plant room.
• Victaulic connections on the evaporator and condenser, easy and fast installation
• Possibility to reverse the heat exchanger water inlet and outlet at the factory
• Fast commissioning, systematic factory operation test before shipment

Wide Application

• Water source heat pumps application
• Ice storage application with temperature down to -6° C to take advantage of off-peak electrical pricing and reduce operating cost
• Suitable for LEED®-certified buildings and green projects, including underground rail systems, five-star hotels and high-end offices
