Airheaters of series 850 for round ducts are designed for direct heating of flowing air and non-flammeble 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. Materials used for our air heaters: air duct in stainless steel 1.4301 (AISI 304), optionally in painted steel CSN® tubular heating elements, exchangeable, in stainless steel 1.4828 Terminal enclosure in steel, powder-coated RAL 7035 Protection class IP-54. Optionally IP-65 Options: With temperature control, temperature limiter, Pt-100 RTD, thermocouple With integrated fan (see table) For a perfect control of our heaters we recommend our electric control systems
