AQUAFORCE® 30XW-VZE
Water-Cooled Screw Liquid Chiller/Heat Pump
With Greenspeed® Intelligence and HFO-1234ze refrigerant

Features

• The 30XW-VZE/30XWHVZE water-sourced units are the premium solution for commercial and industrial applications where installers, consultants and building owners require maximum quality and optimal performances, especially at part load.
• The 30XW-VZE/30XWHVZE units are designed to meet current and future requirements in terms of energy efficiency, versatility and compactness. They feature exclusive inverter-driven screw compressors - an evolution of the proven traditional Carrier twin-rotor screw compressor design.
• Other features include:
  - The new Touch Pilot control.
  - Mechanically cleanable flooded heat exchangers.
  - Refrigerant R-1234ze.
• The 30XW-VZE/30XWHVZE range available in two versions:
  - 30XW-VZE for air conditioning applications.
  - 30XWHVZE for heating applications.
• As standard, the unit can provide an evaporator leaving water temperature down to 3.3°C, and when operating as a heat pump, it can deliver up to 55°C on the condenser side.
• High energy efficiency
  - Inverter-driven twin-rotor screw compressors allow precise capacity matching of building load changes and significantly reduce unit power input, especially at part-load.
  - Flooded multi-pipe heat exchangers for increased heat exchange efficiency.
  - Electronic expansion device permits operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface.
• The 30XW-VZE and 30XWHVZE ranges offer increased global performance as well as Carrier’s acclaimed product quality and reliability. Major components are selected and tested to minimize failures possibility, as well as many design choices have been taken in this perspective.
• Inverter-driven screw compressors
  - Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
  - The inverter is optimised for each compressor motor to ensure reliable operation and easy maintenance.
  - All compressor components are easily accessible on site minimising down-time.
• Refrigerant circuits
  - Two independent refrigerant circuits (from 1000 kW upwards); the second one automatically takes over, if the first one develops a fault, maintaining partial cooling under all circumstances.
  - All components have been selected and tested with R-1234ze refrigerant.
• Safe design
  - Specific polyolester oil qualified by Carrier for use with HFO-1234ze to guarantee and maintain reliable bearing lubrication.
  - Specific compressor gaskets compatible with HFO-1234ze, tested and validated by Carrier.
  - New relief valves designed for operation with HFO-1234ze.
  - New control algorithms.
  - Specific documentation that contains all the installation operation, maintenance and safety instructions.
