Gas guide

  • replaces two shut-off dampers (one flue gas canal is always open)
  • with sealing air 100% lock as per UVV/TRD
  • very high impermeability with various sealing systems without sealing air (short seal length / little sealing air consumption)
  • very little pressure loss (unimpeded cross-section, vane swivels in canal recess)
  • excellent flue gas redirection (slanted position of the vane)
  • simple control (one drive only)
  • very little maintenance required (few mechanically moving parts)
  • space-saving and inexpensive design
