Features

  • The 30XW-PZE liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building owners require optimal perfor­mances and maximum quality.
  • The 30XW-PZE liquid chillers are designed to meet current and future requirements in terms of energy efficiency, flexibility of use and compactness. They use the most reliable technologies available today:
    • Twin-rotor screw compressors with a variable capacity valve
    • R-1234ze refrigerant
    • Touch Pilot control system
    • Flooded heat exchangers that are mechanically cleanable
  • The AquaForce PUREtec range is splitted into two versions:
    • 30XWHPZE for heating applications
    • 30XW-PZE for air conditioning and refrigeration applications
  • As standard, the unit can provide an evaporator leaving temperature down to 3,3°C, and when operating as a heat pump, it can deliver up to 55°C (70°C optional) on the condenser side.
  • R-1234ze long-term refrigerant solution
    • HFO refrigerant with nearly zero global warming potential (GWP < 1) and zero ozone depletion potential (ODP = 0).
  • The 30XW units offer increased global performance as well as Carrier’s acclaimed product quality and reliability.
  • Major components are selected and tested with R-1234ze refrigerant to minimize failures possibility, as well as many design choices have been taken in this perspective.
  • Screw compressors
    • Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
    • All compressor components are easily accessible on site minimising down-time.
  • Refrigerant circuit
    • 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.
  • Evaporator
    • Electronic paddle-free flow switch. Auto-setting according to cooler size and fluid type.
  • Auto-adaptive control
    • Control algorithm prevents excessive compressor cycling (Carrier patent)
    • Automatic compressor unloading in case of abnormally high condensing pressure.
  • Exceptional endurance tests
    • Partnerships with specialised laboratories and use of limit simulation tools (finite element calculation) for the design of critical components.
    • Transport simulation test in the laboratory on a vibrating table and then on an endurance circuit (based on a military standard).
  • Safe design
    • Specific poloyester oil qualified by Carrier for using 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
    • 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

Options

  • Light-brine solution, down to -3°C
  • Master/slave operation
  • Terminal and disconnect options
  • Pump control/power circuit options
  • Waterbox pass, pressure and connection options
  • HLI Communications
  • Condensing temperature control
  • Energy management module
  • Low noise
  • Thermal insulation
