Modular type air source heat pump : The master module can work independently or together with up to 7 slave modules, capacity from 63 to 504kW. Units with W type heat exchanger: panels, frame and base are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents. Units with U type heat exchanger: bearing structure in aluminum, panels in stainless steel, and base in painted section steel. 3-phase scroll type compressor, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers. 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 built with high efficiency tube in tube type heat exchanger, factory insulated with flexible close cell material. Condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins. 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 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 consist of: Compressor contactor, fan motor contactor, compressor protection breaker, fan protection breaker, phase sequence relay and microprocessor with function display (display only for master/packaged unit) Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system. OPTIONAL Paddle flow switch; Metallic filter for hydraulic circuit; Water pump; Rubber antivibration mounting.
