Daikin Altherma 3 M 4-8 kW

The monobloc standard

Functional design

Daikin Altherma 3 M See Through Visual Front

A redesigned casing

The white front grille made of horizontal lines is hiding the fan from view, reducing the perception of the sound produced by the unit.
The light grey and seamless casing is slightly reflecting the environment where the unit is installed, helping it to blend in in any decor.

Monobloc running on refrigerant R-32

Daikin is a pioneer in launching heat pumps equipped with R-32. With a lower Global Warming Potential (GWP), the R-32 is equivalent in power to standard refrigerants, but achieves higher energy efficiency and lower CO2 emissions. Easy to recover and reuse, R-32 is the perfect solution for attaining the new European CO2 emission targets.



Consistent compactness

The monobloc is the ideal solution for places that have limitations on space. No additional indoor unit is required, and the monobloc can fit right under a window to save outdoor space.
