Steam Joint - Deltasint Stationary Siphons

In 1985 Deublin introduced a new technology for condensate removal from paper machine dryers. For the first time, a Stationary Siphon System had been designed and successfully applied to high-speed paper making.

Deublin has pioneered the application of Stationary Siphons on high-speed machines. Today, there are over 15,000 successful installations and Deublin has become the system of choice with many of world’s most productive and efficient papermakers.

The Deublin FSU/Deltasint Stationary Siphon provides the following advantages:

  • Reduction of differential pressure
  • Reduction of blow through steam
  • Elimination of dryer flooding
  • No moving parts
  • Rigid mechanical mounting
  • Hydro-planing Siphon pick-up Shoe design
