Product: CO2 Booster System ONYX

The ONYX series are simple, integrated transcritical booster systems for medium (MT) and low temperature (LT) supermarket applications designed by Commercial Refrigeration Services (CRS) South Africa. The ONYX CO2 booster system makes use of parallel compression and ejectors, increasing energy efficiency by 25-35% and making CO2 a viable refrigerant choice even in high temperature regions. ONYX uses a two-stage compression cycle with a common condenser and liquid line for MT and LT applications. The two-stage design prevents significant energy losses as no big heat exchangers are required to condense the LT side. The integrated multi-temperature solution thus allows each ONYX unit to fully exploit the advantages of CO2.
