Features

• Structure with supporting frame, made of galvanised sheet metal with additional protection provided by polyester powder coating.
• DC INVERTER Scroll and ON-OFF Scroll compressors with oil sight glass, internal overheat protection and crankcase heater.
• Axial fans directly coupled to an electric motor with external rotor.
• Condenser made of copper tube and aluminum finned coil or aluminium MICROCHANNEL coil.
• Evaporator AISI 316 stainless steel braze welded plates type with one circuit on the refrigerant side and one on the water side in 172-P÷372-P models; with two independent circuits on the refrigerant side and one on the water side in 484-P÷574-P models, complete with water differential pressure switch. On the Heat Pump units it is always installed an antifreeze heater.
