Description

Subcritical CO2 compressor racks with single or double suction, offering a total cooling capacity from 50 to 300 kw.

  • Subcritical cycle with single or double suction

A subcritical CO₂ condensing unit for negative temperature can be combined in cascade with a water or glycol condensation circuit. Double suction allows cooling production for ultra-lowtemperature services (deep-freezing) or even positivetemperature services.

CONSTRUCTION

  • Construction in a galvanised sheet steel structure with epoxy paint.
  • Instrumentation panel with pressure gauges and charging ports.
  • Sealed electrical panel independent from the refrigeration compartment.
  • Emergency unit for R-744 maintenance.
  • Silentblocks for unit installation.

REFRIGERATION CIRCUIT

  • Subcritical semi-hermetic compressor for negative temperature, with high-pressure switch, Rotalock valves, crankcase heater and electronic oil level control.
  • R-744 cascade circuit with single suction, made of copper tube, equipped with high-pressure R-744 liquid receiver, double safety valve, oil separator-accumulator, particle separator, suction filters, safety pressure switch, filter and liquid sight glass.
  • Capacity modulation by frequency inverter (INVERTER) on one compressor.
  • Double pressure control valve.
  • Receiver pressure regulating valves.
  • Pressure regulating valve with relief to medium pressure.

HYDRAULIC CIRCUIT

  • Threaded hydraulic connection up to 2 1/2”, and flanged connection from DN80.
  • Flanged connection from DN80.
  • Double plate heat exchanger for R-744 condensation, sized at 70% of the heat rejection capacity. With shut-off valve, solenoid valve and expansion valve.
  • Plate heat exchanger for liquid subcooling.

ELECTRICAL PANEL AND CONTROL

  • Electronic controller for control of the R-744 system with single suction setpoint.

REFRIGERATION CIRCUIT

  • Change to optional Bitzer.

ELECTRICAL PANEL AND CONTROL

  • Spare programmed electronic control. (Accessories)
  • Electronic control for heat recovery. (Accessories)
