New generation of Carrier 06Z variable-speed twin screw compressor

• Twin screw compressor optimized 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
