Serially produced versatile compact HVAC units designed for installation indoors, with a counterflow heat recovery exchanger with efficiency of up to 93% and highly efficient EC fans. The units are supplied in a versatile version that allows both floor-standing installation and installation below the ceiling. In addition, the sides of the units can be reversed during installation, i.e. supply and extraction air are changed. This ensures a high level of variability during installation on site. The optional accessories (a hot-water heating coil and shut-off dampers etc.) are primarily intended for installation from the outside. Depending on our requirements for their functions, comfort and operation, the units can be equipped with one of the control systems available and operated manually, via time settings or through sensors (such as humidity or CO₂). The units are also available in a so-called “hygienic version” with a certificate from Germany’s institute for the hygiene of HVAC equipment ILH Berlin.
