GEA MultiMAXX M311D.PA2 industrial unit heater

GEA HAPPEL – premium German ventilation technology. The industrial air heaters of this brand are designed for the local heat supply of workshops and halls.

MultiMAXX M311D.PA2 – industrial unit heater. The factory nameplate identifies the specific older unit. By placing multiple units in different parts of the hall, air circulation can also be established.

• 3 × 400 V / 50 Hz: three-phase electrical connection.
• 140 / 90 W electrical power: data of the fan motor, not the heat output delivered by the heat exchanger.
• 0.25 / 0.14 A: rated current of the motor's two operating speeds.
• 1320 / 1050 rpm: speeds checked from the ZIEHL-ABEGG motor nameplate.
• IP54 protection: marking of the original appliance and motor; must be separately verified for the installation environment.

Documentation and equipment: Factory MultiMAXX series documents from 2007 and 2012 downloaded, but the old M3 short type code still needs to be precisely assigned. The heat output of today's HN/HD versions is not applied to the older pieces. The identity of all units in the package and the presence of controllers must be checked.

New price – check: 2026.10.06. Searches on wolf-online-shop.de, heizung-billiger.de, and heizungsdiscount24.de did not yield a verifiable, precisely identical new offer. Custom new offer required with currency, net/gross status, heat exchanger, motor, and control accessories.
