Liquid chillers and heat pumps of the ELFOEnergy WSAT-XEE and WSAN-XEE series are units designed for outdoor installation and best energy efficiency in relation to their reduced size.
The ELFOEnergy series has been the turning point in the evolution of chillers.
Every unit has been conceived and made by applying state-of the art technology, emphasising the qualities of EFFICIENCY , SELF-ADAPTATION and EASY
INSTALLATION that distinguish this product
Thanks to its constructional and electronic peculiarities, ELFOEnergy permits:
4 high energy efficiency, in particular during partial-load operation, thanks to the use of two compressors with different capacities that work on a single refrigerant circuit;
4 Eurovent energy efficiency classification class "A" in heating operation, also in full load condition;
4 adaptability of operating parameters to the load conditions of the connected system, thereby optimising consumption, efficiency and working life of the parts;
4 easy, quick installation thanks to the standard hydronic group and the factory test carried out prior to dispatch;
4 installation of hydronic group with non-standard working head pumps or with double pump .
