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

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.

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