R290 intarCUBE

CONSTRUCTION

• Self-supporting casing made of galvanised sheet steel with weather-resistant polyester coating, with thermo-acoustic insulation in elastomeric foam.
• Removable side panels around the entire perimeter.
• Independent compressor compartment separated from the condensing air flow.
• Sealed electrical panel, independent from the refrigerated compartment.
• Flow and return pressure gauges and thermometers.

FANS

• EC electronic fans with speed regulation by proportional control of the condensing pressure.
• Fans with independent air flow rates.

REFRIGERATION CIRCUIT

• Scroll or semi-hermetic compressors with capacity control, unloaded start and crankcase heater.
• Refrigeration circuit 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).
• Economiser by means of an internal heat exchanger.

HYDRAULIC CIRCUIT

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

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.

COIL

• Copper microtube condenser coil with aluminium fins.

ELECTRICAL PANEL AND CONTROL

• IntarChiller electronic controller with refrigeration control, condensing fan control with floating setpoint, pump control, etc.

CONSTRUCTION

• Stainless steel screws.
• Silentblocks for unit installation. (Accessory)

FANS

• EC radial fans for air discharge to ambient.

REFRIGERATION CIRCUIT

• Heat recovery (20 or 80 % of condenser heat) for hot water production (only without integrated hydraulic module).

HYDRAULIC CIRCUIT

• Integrated hydraulic module with glycol circulating pump with stainless steel body and impeller, expansion vessel, safety valve, mesh filter, thermometers and pressure gauges, air vent and drain connection (except series 8 and units with heat recovery).
• Standby pump.

COIL

• Polyurethane-based anti-corrosion coating for the condenser coil.
• Aqua Aero® anti-corrosion coating for copper microtube finned coil.
• Anti-corrosion treatment on copper microtube and Alucoast® fin coil.
