Pre-heating system

For optimum conditioning of the mat following the pre-compacting process, Siempelkamp has specially developed a mat preheating system which is used before the mat enters the press. During the patented ContiTherm® method, a mixture of hot air and steam is applied to the mat which then quickly, completely and uniformly preheats. The Siempelkamp method thus allows for the economical production of very thick boards.

Technical features:

  • quick, uniform preheating of the mat before it enters the press
  • precise adjustment of preheating temperature between 60 and 95°C
  • high preheating speeds due to steam condensation
  • allows the production of thick boards of up to 60 mm

Customer benefits:

  • capacity increase of up to 30 % when preheating mat to 80 C° - 90 C°
  • increase of product quality
  • significant reduction of mat swelling
  • reduction of the specific pressure inside the press by 30%
  • avoiding the common season-related capacity fluctuations
