GEA MultiMAXX HN21 industrial unit heater

GEA Happel – premium German air conditioning heritage. MultiMAXX unit heaters are designed for space heating of industrial halls and operating areas; FläktGroup documentation is also available for the series.

MultiMAXX HN21 industrial unit heater. It delivers the air heated in the heat exchanger into the room via a fan, making it connectable to the central heating system of a workshop or warehouse.

• Fan and heat exchanger in a single unit: heating heat can be distributed with a local air stream.
• Wall or ceiling mounting: with appropriate factory brackets, usable floor space remains free.
• Air deflection solutions: the series can be ordered with various discharge louvers; the actual blading of the offered unit must be coordinated.
• Sizing according to heat exchanger: heating performance is jointly determined by the medium temperature, air flow rate, and the specific heat exchanger.
• Expandable series: filters, fresh air elements, and controls are listed as factory accessories; the presence of these for the used unit will be clarified separately.
