The units are compliant to the ErP Regulation.

Versions

  • JWV/WP - Reversible Heat Pump

Power range

  • 48,0-164 kW
  • 14,0-47,0 Ton

Features

  • Structure with supporting frame, made of galvanised sheet metal with additional protection provided by polyester powder coating.
  • Scroll compressors with oil sight glass, internal overheat protection and crankcase heater.
  • Axial fans directly coupled to an electric motor with external rotor.
  • Evaporator AISI 316 stainless steel braze welded plates type with one (mod. 051÷091) or two (mod. 112÷182) independent circuits on the refrigerant side and one on the water side, completed with water differential pressure switch, and antifreeze heater.
  • R290 refrigerant.
  • The condensing / evaporating control is included: electronic proportional device that ensures efficient and continuous functioning of the unit. It also allows to reduce the sound level especially at night. It consists of a fans speed controller with continuous speed regulation, an high/low pressure transducer on cooling circuit and an electrical heater on electrical board.
  • The production of hot water up to 70 °C is reachable with outside air temperature down to 3 °C. With outside air temperature of -20 °C the reachable production of hot water is up to 55 °C.
