GEA MultiMAXX HN21 industrial unit heater

GEA Happel – premium German air technology tradition. MultiMAXX unit heaters were developed for space heating of halls and industrial 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 using a fan, making it connectable to the central heating system of a workshop or warehouse.

• Fan and heat exchanger in one unit: the heating heat can be distributed with a local air stream.
• Wall or ceiling mounting: with appropriate factory brackets, the useful floor space can remain free.
• Air deflection solutions: the series can be ordered with various diffusers; the actual lamella configuration of the offered unit is to be agreed upon.
• Sizing according to heat exchanger: the heating capacity is determined jointly by the fluid temperature, air volume, and the specific heat exchanger.
• Expandable series: filter, fresh air element, and control are listed as factory accessories; the presence of these in the used unit will be clarified separately.

Documentation: the factory MultiMAXX HN operation and installation manual downloaded, includes the HN21 type size (DC-2011-0143-DE, 2020.05/R6). The full type code, heat exchanger, and motor of the old GEA instance still need to be matched; the document is a series overview, not a guarantee of every accessory of the old unit. The series material is available; the handover documentation belonging to the specific design is to be agreed upon.

New comparison price: the new FläktGroup HN21.UWARAP.BKD version on Ventilatory.net 710.20 EUR net / 859.34 EUR gross. Verification: 2026.10.10. The base unit features a Cu/Al hot water heat exchanger and a two-speed, 3×400 V motor. Bracket, thermostat, switch, installation, and transport are quoted separately. The full version code may differ from that of the offered old unit, therefore this is a comparison, not its exact new price. Verified price source.
