ECO₂CUBE

Description

ECO2CUBE transcritical CO₂ air-cooled plants with double suction, parallel compressor and refrigerated gas-cooler integrated for medium power commercial cooling applications from 20 to 60 kW.

• Casing built with galvanized steel sheet with epoxy paint for outdoor use with electrical panel and Gas-Cooler.
• Available in 50 and 60 Hz. Other voltages by request.
• Dorin CO₂ semi-hermetic compressor rack: 2 PT compressors, 1 parallel compressor and up to 2 NT compressors, with rotalock valves.
• Inverter capacity control per group of compressors (optional in NT).
• Variable speed axial or radial (optional) fans with EC motors.
• High pressure sector (SP = 120 bar) made with copper microtubes and equipped with:
  – Separator – oil trap accumulator with filter and electronic oil injection on each compressor.
  – Condenser / gas-cooler, made with copper microtubes and aluminum fins.
  – Internal economizer to ensure sufficient superheat in the parallel compressor suction.
  – High pressure switch, double safety valve.
  – Double gas-cooler pressure control valve.
• Intermediate pressure sector (SP = 52 bar) made of copper tubing and equipped with:
  – High pressure liquid CO₂ container with double safety valve.
  – Pressure regulating valve (flash-gas) with medium pressure relief. To the positive tempreature suction line.
  – Sub cooler to ensure of the liquid line subcooling.
  – Liquid line with filter drier and sight glass.
• Positive temperature suction line (SP = 45 bar), made of copper tubing and equipped with a double safety valve.
• Negative temperature suction line (SP = 30 bar), made of copper tubing and equipped with a double safety valve.
