ECO2rack

Rack of compressors subcritical CO2 cycle with double suction in cascade

CO2 air cooled condensation refrigeration plants.

Description

Rack of single or double suction CO2 compressors in transcritical cycle, or in subcritical cycle condensed by glycol or refrigerant. ECO2Rack condensing units can be built in various combinations of 2 or 3 compressors to offer a total cooling capacity of 50 to 300 kW. Ces équipements se distinguent par :

  • Large maintenance access.
  • Custom design.

 

  • Construction in galvanised sheet steel structure with epoxy paint.
  • Sets of up to 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 injection per compressor.
  • Medium pressure CO2 receiver (PS: 60 bar) with double safety valve led to the outside.
  • Economiser – liquid CO2 subcooler.
  • Refrigeration circuit made of copper tube, equipped with filter drier.
  • Instrumentation panel with pressure gauges and load taps.
  • Integrated control and power panel with electronic control unit for compressor management and electronic valves.
  • Emergency unit for CO2 maintenance.
