TECHNICAL CHARACTERISTICS
The reversible
heat pumps US series are designed for applications in residential and commercial areas, these units are extremely
versatile and can operate in heat pump mode with the ability of producing hot water at a temperature of 63°C using the electric
heaters for environmental heating and sanitary applications.
The new US system, which is the result of the evolution of the previous model, is the ideal solution for the total home climate
control (with the accessories Evo Touch (unscheduled) and HNS Box). For new or already existing house if equipped with a radiant
floor or fan coil as heating system, with feeding from electric power network and a renewable energy sources.
The INVERTER compressor with brushless DC motor technology, matched with electronic expansion valve, pump and variable
speed blower always with brushless motor, as well as the integrated circulators, optimize the power consumption and the
operation efficiency of the refrigerating components and of the entire system.
6.1
FRAME
All US units are made up of hot-galvanized thick sheet metal, painted with polyurethane powder enamels at 180°C to ensure the
best resistance against atmospheric agents. The frame is self-supporting with removable panels. All screws and rivets for outdoor
installations are in galvanized stainless steel. The indoor units also have a self-supporting structure made of galvanized steel with
removable painted panels.
