For CO2
SK series / subcritical
The range of compressors for subcritical CO2 applications, has been developed taking into account the most recent requirements from the refrigeration technologies and by manufacturers of refrigerating applications for supermarkets.
The compressors are ideal for use with hybrid systems (ie. cascade system) and, in combination with the compressors Frascold TK series for transcritical CO2 applications, they offer the possibility to built-up multi-compressor installations for medium and low temperature (booster systems).
The parameters considered during designing phase, allow the use of SK3 models in an extended working range with higher evaporation temperatures and condensation. Similarly, also the maximum permissible stand still pressure Pss is higher, allowing the use of these compressors even when the increase of pressure represents a limitation for building the plant itself.
