• Sets of 2 or 3 CO2 compressors equipped with rotalock valves.
• Inverter capacity control per compressor group.
• Particulate separator and CO2 filter.
• Oil separator and accumulator with oil filter and electronic compressor injection.
• Medium pressure CO2 receiver (PS 60 bar) with double safety valve.
• Economiser – liquid CO2 subcooler.
• Refrigeration circuit made of copper tube.
• Instrumentation panel with pressure gauges and load taps.
• Integrated control and power panel with electronic control unit for compressor and electronic valve management.

• Set of 2 or 3 transcritical CO2 compressors and set of compressors in parallel. Inverter drive in one compressor of each set.
• Cooler gas pressure regulating valves.
• Vessel pressure regulating valves.
• Internal economiser exchanger.
• Gas cooler with copper tube coils and aluminium fins in parallel.
• PS: 120 bar. Variable speed EC axial motor fans.

• Double cascade plate heat exchanger with gravity circulation.
• High temperature refrigerant R-290 or HFC.
• Semihermetic high temperature compressors, with Inverter drive in one compressor.
• High temperature circuit made of copper, with filter, sight glass and electronic expansion valves.
