Air Heater Type 850

Air heaters of series 850 for round ducts are designed for direct heating of flowing air and non-flammable gases and mixtures. Typical applications are in the field of ventilation and air conditioning as well as in drying equipment and process engineering. Air duct heaters in this design are used for overpressure up to 10 mbar. For higher pressures, we design air heaters gas-tight welded according to Series 803 or as electric circulation heaters.
