The Stream series with 4-cylinder CO2 compressors is the ideal solution for R744 refrigeration, cascade, and booster systems that require high suction pressures up to 90 bar. The use of transcritical compressors on the maintenance/transcritical side, as well as on the freezing/subcritical side, ensures that in the event of a power outage, the refrigeration system remains fully resilient with no interruption of operation.
