GEA Happel MultiMAXX M312A.PA2 industrial unit heater

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

MultiMAXX M312A.PA2 – industrial unit heater. The factory data plate 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 two operating stages of the motor.
• 1320 / 1050 rpm: speeds verified from the ZIEHL-ABEGG motor nameplate.
• IP54 protection: designation of the original appliance and motor; must be specifically checked for the installation environment.

Documentation and equipment: The 2007 and 2012 factory MultiMAXX series documents have been 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 verified. On the main nameplate of the M312A, the A/W rows are swapped; the electrical data was recorded based on the motor's own nameplate.

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