CHA/F/ML/WP 52÷92
A CLASS ENERGY EFFICIENCY AIR COOLED REVERSIBLE HEAT PUMPS FOR HIGH TEMPERATURE HOT WATER PRODUCTION WITH AXIAL FANS, SCROLL COMPRESSORS AND PLATE EXCHANGER
This innovative series of high-efficiency heat pumps is designed for hot water production up to 65 °C and reliable operation at outdoor temperatures down to -20 °C. Equipped with scroll compressors and axial fans, the units ensure consistent and efficient performance under demanding conditions.
Developed to create and maintain optimal comfort throughout the year, the system is particularly suitable for areas with high daily occupancy, such as commercial and service-sector environments. It independently manages winter heating, summer cooling and the production of high-temperature domestic hot water.
Thanks to its compact and thoughtfully engineered design, installation is straightforward and efficient. By using only electrical energy combined with the heat naturally present in the ambient air, the system transfers heat effectively to indoor spaces. This results in substantial energy savings, high reliability and fast start-up times.
The units comply with the ErP Regulation.
