A CLASS ENERGY EFFICIENCY AIRCOOLED REVERSIBLE HEAT PUMPS WITH EC INVERTER AXIAL FANS, INVERTER ROTARY COMPRESSOR, PLATE EXCHANGER AND HYDRONIC KIT.
The reversible Heat Pumps CHA/IK/ML/A 18÷35 with A CLASS energy efficiency are designed for small domestic or service sector environments. Equipped with R410A refrigerant, Inverter Rotary compressor with DC BRUSHLESS motor and EC INVERTER axial fans, they are extremely functional and reliable units. The Inverter device controls and continuously modulates the compressor speed, keeping the temperature of the water delivered to the system stable and constant and adapting it perfectly to the thermal load of the places where terminal units it feeds are installed. This obtains high energy efficiencies and SCOP values higher than conventional unit, and a reduction of compressor starting peak currents, thus considerably reducing the risk of malfunctioning or breakages. The EC Inverter axial fans vary their speed according to the required thermal load, with consequent benefits in terms of energy efficiency and silent operation.
The unit is designed for hot water production up to 55°C.
