High reliability and easy servicing

  • 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
  • Industrial-type screw compressors with oversized bearings and motor cooled by suction gas
  • All compressor components are easily accessible on site minimizing down-time
  • 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
  • Auto-adaptive control
  • Exceptional endurance tests

Safe Design

  • Specific polyol ester 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

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 minimizes the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
