Q9-7TK Compressor

  • TK series compressors for transcritical CO2 applications
  • 4-Cylinder semi-hermetic compressor 


Description

The range of Frascold TK series compressors for transcritical CO2 applications has been developed taking into account the most recent changes in refrigeration and heating technologies. Specifically, the TK compressores are designed for CO2 applications with transcritical process, such as heat pumps, medium temperature refrigeration systems; in addition to cascade and booster systems in which the TK compressor, in combination with an SK compressor for CO2 application with sub-critical process, allow the realisation of multi-compressor systems for low and medium temperature.
