Air-water heat pump without external unit ATHENA-C

Air-water heat pump DC Inverter monoblock indoor unit for heating, air conditioning and DHW production

Invisible full DC Inverter heat pump for DHW production

ATHENA-C is a fully integrated 3-in-1 heat pump: it works in heating and cooling mode and produces domestic hot water up to 55°C.
The ATHENA-C heat pump can be connected to an external tank, both for DHW production and for heating and cooling with technical water, through hydronic terminals or a floor system (radiators and radiant panels). It can also be combined with a solar panel system.
The heat pump without external unit is invisible, quiet and compact. The new ATHENA-C model is the most suitable solution for historical centres, prestigious constructions and wherever it is necessary to protect the architectural decorum of the building. ATHENA-C has been developed to be installed completely inside the building; it is necessary to foresee the realisation of a direct connection with the outside, through a hole on the perimeter wall for air inlet and outlet, concealed by a paintable grille.
ATHENA-C combines all the components of the heat pumps in a single unit with extremely reduced dimensions: technology, characteristics and performance of the centrifugal fan model are in line with those of the Monobloc and Split models.
