CO2 DX Packs

Energy efficient transcritical and subcrital CO2 compressor pack systems for medium and low temperature applications. Designed with knowledge for operation and controls for optimisation.

Product Detail

Two highly advanced CO2 DX Packs. The CO2 DX 2 Stage Booster Pack provides both low temperature freezing (LT) and medium temperature (MT) in the same refrigeration circuit. The CO2 DX MT Pack is designed for medium temperature only. Both systems require direct expansion modulating valves on cases and coolers to provide the maximum energy optimisation. The Guardian Controls GC-45 and E636 controllers provide energy optimised control, deliver superb product temperatures, safe operation and smooth transitions from suncritical to transcritical CO2 phases.

Key Benefits

  • Energy optimised control and control methodologies.
  • Stable transitions
  • Low energy consumption
  • Simple installation and low service costs.
  • Compact design with low noise.
