Transcritical TK series for CO2
The TK series compressors for transcritical CO2 applications, has been developed keeping in mind the latest requirements from the refrigeration and heating technology.
Specifically, the TK compressors are designed for application with CO2 transcritical process, such as heat pumps and refrigeration systems in medium temperature, as well as cascade and booster systems in which the TK compressor, in combination with an SK compressor for CO2 application with subcritical process, allow the construction of multi-compressor systems for medium and low temperature.

TK series for transcritical application
■ 7 models (4 for heat-pump use), 2 cylinders with displacement from 1,9 to 3,5 m3/h [50Hz] and nominal motor power from 3 to 5 Hp.
■ 21 models (10 for heat-pump use), 4 cylinders with displacement from 3,8 to 25,3 m3/h [50Hz] and nominal motor power from 5 to 40 Hp.
■ Max allowable pressure (high side) Pss = 140 bar [155 bar for D series]
■ Max allowable pressure (low side) Pss = 80 bar [100 bar for D series]
■ POE oil charge [PAG oil on request] Applications
■ Refrigerating systems in mid and high temperature
■ “Booster” systems
■ “Heat-pump” systems

RSH - Patented Capacity Control

Frascold's patented Reduced SuctionHead technology allows our reciprocating compressors to run unloaded indefinitely. Unlike standard capacity control, RSH capacity lets the compressor run without overheating while energized. This revolutionary feature provides application flexibility while reducing heat, vibration and damage from unloading stress.

  • 2,4,6 and 8 Cylinders
  • Reduced wear and vibration
  • Run unloaded indefinitely
  • Efficient & reliable unloading
  • Frascold exclusive solution
  • Retrofit existing compressors
