  • Heating capacity up to 200 kW
  • Cooling capacity up to 34 kW

MultiMAXX HD - The powerful unit heater

Powerful heating

Externally, MultiMAXX HD are almost exactly identical to the HN models. Both are available with design panels or in functional industrial versions - and the dimensions of HD sizes 1 to 4 conform to the standard.

A look inside, however, shows the big differences. A diagonal fan really puts on the air pressure with HD models. With dimensions comparable to its brother models, this powerful fan offers higher air ratings, greater air-projection distances, and enhanced heat input.
