GEA HAPPEL 4111 industrial fan heater, 11.2 kW

GEA HAPPEL – premium German ventilation technology. The brand's ventilation equipment is used for heating and air handling in industrial spaces.

HAPPEL 4111 – 11.2 kW unit heater at the operating point specified on the data plate. Thermal output should always be evaluated together with the water and air temperature.

• 11.2 kW heating output: stated on the data plate at 90/70 °C heating medium and +15 °C intake air.
• 2350 m³/h air delivery: value from the device data plate, at the specified point of 1400 rpm.
• Three motor speeds: the ZIEHL-ABEGG motor data plate indicates 1380 / 1050 / 700 rpm.
• 0.16 / 0.13 / 0.04 kW motor data: electrical power of the fan, not the heating output.
• 380 V / 50 Hz: three-phase connection with IP44 motor protection.

Documentation and equipment: Exact 4111 factory PDF is still missing. The pressure and temperature lines on the device data plate have contradictory placements, therefore no confirmed operating limit is published from them. The 11.2 kW output is not identical at all water temperatures.
