Welded Plate Heat Exchanger

Welded plate heat exchangers incorporates the performance advantages of a gasketed plate heat exchanger without the temperature, pressure, and compatibility limitations of having gaskets. The plate pack welding technology is patented and has been in production at Tenez for more than 20 years. The technology is robust and cost effective!

Advantages of Welded Plates

image7

Plate heat exchangers are versatile and inexpensive however the elastomer gaskets can be problematic for some applications. Below are some of the advantages of a welded plate exchanger:


  • Gaskets age and need to be replaced on occasion. All welded exchangers can keep operating indefinitely.
  • Gasket compatibility is not an issue.
  • Equipment can be run at much higher temperatures, up to 300°C.
  • Capable of operating at high pressures, up to 25 bar without risk of spraying from gaskets.
