1. The master module can work independently or togetherwith up to 7 slave modules, capacity from 9kw to 504kw.

2. Units with V type heat exchanger: panels, frame andbase are made from galvanized steel protected withpolyester powder painting to ensure total resistance toatmospheric agents.

3. Units with U type heat exchanger: bearing structure inaluminum, panels in stainless steel, and base inpainted section steel.

4. 3-phase scroll type compressor, with built-in thermaloverload cut-out and crankcase heater, mounted onrubber vibration dampers.

5. External rotor type axial fans, equipped with threephase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.

6. Evaporator built with high efficiency tube in tube typeheat exchanger, factory insulated with flexible close cellmaterial.

7.Condenser built with seamless copper tubesmechanically expanded into blue hydrophilic aluminumfins.

8.Refrigerant circuit complete with charge valves, filterdrier, sight glass, gas-liquid separator, thermostaticexpansion valve, high & low pressure switch. The heatpump unit is completed also with 4-way valve, liquidreceiver and one way valve.

9. Hydraulic circuit built with galvanized pipe, complete withwater discharge connection for tube in tube heatexchanger and flange type hydraulic connectors in twodirections easy for connections from both sides of theunits.

10.Electric panel consist of: compressor contactor, fan motorcontactor, compressor protection breaker, fan protection breaker, phase sequence relay and microprocessor with function display (display only for master/packaged unit)

11.Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.
