AquaForce^® - Premium water-cooled screw liquid chiller using HFO R-1234ze refrigerant or R-515B
30XW-PZE

Low energy consumption

• Compliant with EU Eco-design Minimum Efficiency Performance Standards (MEPS) in cooling
• SEER 12/7° up to 7.6 and SPER 12/7° up to 9.3
• Twin-rotor screw compressor equipped with a high-efficiency motor and a variable capacity valve that permits exact matching of the cooling capacity of the load
• Flooded multi-pipe heat exchangers for increased heat exchange efficiency
• Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface
• Economiser system with electronic expansion device for increased cooling capacity

Low operating sound levels

• Silencers on the compressors discharge line
• Silencers on the economiser return line
• Acoustic insulation on the components that are most subjected to radiated noise
• Option 257 further reduces the global unit sound level

Easy and fast installation

• Compact design
• Simplified electrical connections
• Simplified hydraulic connections
• Fast commissioning

Environmental care

• PUREtec™ R-1234ze long-term refrigerant solution
• R-515B future-proof A1 refrigerant
• Leak-tight refrigerant circuit

High reliability and easy servicing

• Increased global performance
• Major components are selected and tested with R-1234ze and R-515B refrigerant to minimise failures possibility, as well as many design choices have been taken in this perspective
• Industrial-type screw compressors with oversized bearings and motor cooled by suction gas
• Two independent refrigerant circuits
• Auto-adaptive control
• Exceptional endurance tests

Safe Design

• Specific polyol ester oil qualified by Carrier for using with HFO-1234ze or R-515B to guarantee and maintain reliable bearing lubrication
• Specific compressor gaskets compatible with HFO-1234ze or R-515B, tested and validated by Carrier
• New relief valves designed for operation with HFO-1234ze or R-515B
• Specific electrical box with increased tightness and integrated blower that maintains positive air pressure to avoid any risk of ignition
• New control algorithms
• Specific documentation that contains all the installation, operation, maintenance and safety instructions

06T twin-rotor screw compressor

• Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
• Optimal adjustment of the compressor cooling capacity
• If a fault occurs, the compressor does not switch off, but continues operation with a reduced capacity (unloaded mode)
• The silencer in the discharge line considerably reduces discharge gas pulsations for much quieter operation
• Condenser includes an oil separator that minimises the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function

SmartVu™ control

• Intuitive and user-friendly, coloured, 4.3" interface
• 10 languages available
• Easy access to the controller box
• Password protection
• Night-modex
• Energy management

Remote management (standard)

• Units with SmartVu™ control can be easily accessed from the internet, using a PC with an Ethernet connection. This makes remote control quick and easy and offers significant advantages for service operations
• Communicates with other building management systems via optional communication gateways
• The following commands/visualisations are possible from remote connection:
  • Condenser pumps control: a digital input allows verification of condenser water flow (the flow switch must be supplied by the installer)
    
  • Start/Stop of the machine
    
  • Dual set-point management through a dedicated contact is possible to activate a second set-point (example: unoccupied mode)
    
  • Demand limit setting: to limit the maximum chiller capacity to a predefined value
  • Operation visualisation: Indication if the unit is operating or if it is in stand-by (no cooling load)
    
  • Alarm visualisation
