MPC subcritical CO2 cascade refrigeration system

By Arneg, published Jul 11, 2017

Medium Power Cascade MT-LT integrated system ideal for medium size retail shops. Refrigeration capacity at NT is between 20 and 180 kW. The system uses 2, 3 or 4 compressors.

Refrigeration capacity at LT is between 4 and 70 kW, using 2 or 3 compressors.


  • Low energy costs: Adopting a cascade-system rather than a traditional system using synthetic refrigerant, it becomes possible to achieve higher levels of efficiency, which translate into lower energy costs.
  • Smaller dimensions, lower costs: MT and LT in a single, compact system, costing less to run than two separate refrigeration units.
  • High reliability: The MPC is equipped with dual CO2 condensing circuits, so that the unit can be kept running even while maintenance is in progress.
  • Ease of maintenance and installation: using 3D computer-aided design, the various components of the unit were positioned in such a way as to guarantee ease of access for maintenance purposes.
