Production ended on 31.08.2023
The Manufacturing of the ventilation unit Vallox 121 has ended.
See model Vallox 125 MV. It replaces old MUH Ilmava units and Vallox 121 units. The replacement is very easy as there is no need for duct system modifications.
Suited for small and medium-sized homes, the popular Vallox 121 SE ventilation unit is equipped with the Vallox Digit SED control panel.
Control of the Vallox 121 SE ventilation unit can be automated with the optional humidity and carbon dioxide sensors and the week clock on the control panel. The summer/winter automation of the energy-efficient unit automatically bypasses the heat recovery cell during the hot summer months. The annual efficiency of the unit is 74%.
The ventilation unit is controlled with the control panel delivered with the unit.
