THERMICA is the innovative series of high energy efficiency Heat Pumps dedicated to hot water production up to 65 °C and operation up to -20 °C of external air temperature, with Scroll compressors and axial fans. The unit, designed to originate and control – throughout the year – the best comfort conditions in rooms with a high rate of daily attendance, such as enclosed areas destined to the activities of the service sector, autonomously handles winter heating, summer air conditioning and the production of high temperature domestic hot water. The THERMICA series, designed with an extremely compact structure for simple installation operations, uses only the electric energy and the heat accumulated in the air, to transfer heat to the rooms, thus allowing considerable energy savings, a high rate of reliability and the shortest start-up times.
The units are compliant to the ErP Regulation.
