- R-134a : HFC refrigerant with zero ozone depletion potential
- 40% less refrigerant allowed by the micro-channel technology
- Leak tight refrigerant circuits
- Software leak detection + alert
- Refrigerant leak detection input (option)
- LEED® (Leadership in Energy and Environmental Design) certification
- Twin screw compressor optimised for variable speed operation
- Separate air-cooled inverter drive for increased reliability
- Integrated Resonator Array (IRA) to reduce the sound level by up to 6 dB(A) when compared with previous 06T generation
- Integrated Check Valve for quiet shutdown
- Bearing life exceeding 100,000 hours
- A dedicated oil separator is installed at the discharge of each compressor to ensure maximum oil return
- Volume index control (Vi) valve provides a reliable method of adjusting the compression ratio to better match system demand
- Screw compressors work on the positive displacement principle to compress gas to a higher pressure. As a result, if there is an unusually high pressure in the condenser, the compressor does not switch off, but continues operation at reduced capacity (unloaded mode)
- The silencer in the oil separator line considerably reduces discharge gas pulsations for much quieter operation
