Characteristics

Structure
The master module can work independently or together with up to 15 slave modules, cooling capacity from 60 to 2048kW.
Hermetic compressor
3-phase scroll type compressor, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.
Axial fan
External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.
Evaporator
Evaporator built with high efficiency tube in tube type heat exchanger, factory insulated with flexible close cell material.
Condenser
Condenser built with seamless internal screw thread copper tubes mechanically expanded into blue wave hydrophilic aluminum fins.
Refrigerant circuit
Refrigerant circuit complete with charge valves, filter drier, sight glass, gas-liquid separator, thermostatic expansion valve, high & low pressure switch. The heat pump unit is completed also with 4-way valve, liquid receiver and one way valve.
Hydraulic circuit
Hydraulic circuit built with galvanized pipe, complete with water discharge connection for tube in tube heat exchanger and flange type hydraulic connectors in two directions easy for connections from both sides of the units.
Electric panel
