R290 intarWatt – Full INVERTER

CONSTRUCTION

• Compact construction with V-shaped condensers.
• Self-supporting casing made of galvanised sheet steel with weather-resistant polyester coating.
• Removable side panels around the entire perimeter.
• Sealed electrical panel, independent from the refrigerated compartment.

FANS

• Two electronic fans per refrigeration circuit with variable speed.

REFRIGERATION CIRCUIT

• Semi-hermetic compressors with capacity control,unloaded start and crankcase heater and INVERTER drive on each compressor.
• Refrigeration circuits made of annealed copper tubing with brazed joints, filter drier, ATEX high and low pressure switches, pressure transducers and temperature probes.
• Stainless steel plate evaporator(s) brazed with pure copper and electronic expansion valve(s).

HYDRAULIC CIRCUIT

• Hydraulic circuit made of copper tubing with threaded or flanged connections, with filling/drain valve, air vent, flow switch, and inlet and outlet thermometers and pressure gauges.

SECURITY

• ATEX fans for continuous ventilation of the refrigeration compartment.
• Leak detector with audible and visual alarm.
• Shunt trip coil for cutting off the power supply line to electrical components located in the refrigeration compartment.
• Safety valve on the high- and low-pressure sides for common ducted discharge.
• Independent power supply for the exhaust fan and leak detector, with residual-current and thermal magnetic protection. Flow switch supplied separately.

COIL
