MAIN COMPONENTS
FRAMEWORK
Base, self supporting frame and paneling in steel plate with protective surfaces treatment in compliance with UNI ISO 9227/ASTMB117 and ISO 7253, and painted with epoxy powders.
Colour: RAL 9002

COMPRESSORS
Orbiting spiral (SCROLL) hermetic compressors with spiral profile optimized for R410A refrigerant.
ON / OFF capacity control (0 / 100% each compressor).
2-pole 3-phase electric motor with direct on line starting.
Phase sequence electronic relay.
Crankcase heater.
Electric motor thermal protection via internal winding temperature sensors.
Rubber supports.

PLANT SIDE HEAT EXCHANGER
Copper brazed plate type with cover plates, plates and connections in AISI 316 stainless steel:
With single refrigerant circuit for S version machines.
With double refrigerant circuit for D version machines.
Anticondensate insulation made of polyurethane.
Temperature sensors on water inlet and outlet.
Differential water pressure switch for water flow control.

REFRIGERANT CIRCUIT
Components for each refrigerant circuit:
Reversing valve for refrigeration cycle inversion.
Electronic expansion valve. The valve allows high performance and system efficiency thanks to a timely and accurate response to changes in temperature and pressure. The expansion valve is equipped with energy reserve to allow the closure of the valve in the event of lack of power supply.
Sight glass.
Filter dryer on liquid line.
Service valves on liquid line and gas discharge.
Non-return valve.
Safety valves on high and low pressure side.
Pressure transducers with indication, control and protection functions, on low and high refrigerant pressure.
High pressure safety switch with manual reset.
Liquid receiver with accessories.
Oil drainage and oil recovery systems.
IDEA® defrosting system.
RC Group patented defrosting system based on a dynamic reading of the evaporating parameters.
Through sensors the microprocessor realize the real ice presence on the gas/air heat exchanger and activates the defrosting cycle only when necessary, with consequent energy saving.
Valves on gas delivery and liquid return for coupling to remote air cooled
condenser.
0÷10V proportional signal to manage the condensing/evaporating control system of the remote air cooled condenser.
Refrigerant circuit with copper tubing with anticondensate insulation of the
suction line.
Plastic capillary hoses for pressure sensors connection.
R410A refrigerant charge.
