Description
INTARCON’s ECO2Watt subcritical CO₂ condensing units provide industrial refrigeration for low-temperature commercial and industrial applications. Their cascade technology combines CO₂ (R744) and propane (R290) to maximise energy efficiency and ensure reliable operation. These condensing units offer excellent cooling performance in cold rooms and freezing tunnels.
- Cascade cycle
The CO₂ cascade cycle with a high-temperature R290 (propane) cycle offers excellent cooling performance in negative temperature applications, such as cold rooms or freezing tunnels.
CONSTRUCTION
- Compact construction with V-type condensers.
- Self-supporting casing made of galvanised sheet steel with weatherproof polyester paint.
- Removable side panels around the entire perimeter.
- Sealed electrical panel independent from the refrigeration compartment.
- Emergency unit for R-744 maintenance.
FANS
- EC electronic fans with speed regulation by proportional control of the condensing pressure.
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.
- R-290 circuit made of copper, equipped with oil separator, high- and low-pressure switches, filter drier and liquid sight glass.
- Capacity modulation by frequency inverter (INVERTER) on one compressor.
- Instrumentation panel with pressure gauges, built-in electrical panel with residual current and thermalmagnetic protection for each element.
- High-temperature refrigeration circuit made of copper, equipped with oil separator, high- and low-pressure switches, filter drier and liquid sight glass.
- Double plate heat exchanger for R-744 condensation, sized at 70% of the heat rejection capacity, with gravity circulation. With shut-off valve, solenoid valve and expansion valve.
- Plate heat exchanger for liquid subcooling.
SECURITY
- ATEX fans for continuous ventilation of the refrigeration compartment.
- Leak detector with audible-visual alarm.
- Trip coil for cutting off the power supply line to electrical components located in the refrigeration compartment.
- Emergency unit for cooling the R-744 during maintenance when out of service, or in the event of critical failure or power failure.
- Independent electrical supply for the extraction fan and leak detector, with residual current and thermalmagnetic protection.
