Transcritical CO2 refrigeration systems
Transcritical C02 System
Naturally innovative
This pioneering provision cooling system is especially engineered for environmentally friendly and dependable use on superyachts using the natural refrigerant CO2 (R744). Combined with a new innovative Bock HR StarCO2mpressor GIRSCHNER’s new transcritical CO2 system is the lightest and smallest provision cooling system ever. Higher operating pressure means more capacity in the same space. Like our standard series of cooling systems, the new CO2 series are equipped with a PLC control system and brand-leading parts for the highest reliability and efficiency.
