Thermal Process Air Treatment with Electrical Auxiliary Heater

Thermal process air treatment with electrical auxiliary heater
  • Concentric construction
  • Heat exchanger tubes welded at their cold end
  • Heat exchanger tubes seated in compressable sealant on the hotter end allowing thermal elongation
  • Welded joints generally in zones of low mechanical / thermal stress



EEC = Energy- and Emission Controlled Process Air Treatment


The principles of this technique are:

  • Integrated process air treatment adapts to the variable VOC output of the impregnating plant
  • Recirculation energy
  • Reduction and regulation of airflows corresponding with:
    • the oxygen requirement of the combustion
    • the conditions of self-supporting combustion
    • the operating safety limits
