ECO₂Watt

Description

ECO2Watt are great cooling capacity CO2 condensing units, single or double suction transcritical cycle with built-in gas cooler, or in cascade cycle, designed according to the needs of the installation for a total cooling capacity between 80 and 300 kW. These equipment are characterised by:

• Large maintenance access.
• No engine room.
• Custom design.

• Construction in galvanised sheet steel structure with epoxy paint.
• Sets of 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.
• Instrumentation panel with pressure gauges and load taps.
• Integrated control and power panel with electronic control unit for compressor and
  electronic valve management.
• Emergency unit for CO2 maintenance.

Transcritical ECO2Watt

• Set of transcritical CO2 compressors and set of compressors in parallel. Inverter drive in one compressor of each set.
• Double pressure control valve.
• Pressure regulating valve with medium pressure relief.
• Internal economiser exchanger.
• Gas cooler with copper tube coils and aluminium fins in parallel.
• PS: 120 bar. Variable speed EC axial motor fans.

Cascade ECO2Watt

• Up to triple 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.
• Copper tube and aluminium finned coil condenser in parallel V configuration.
• Variable speed EC axial motor fans.
