PILLOW PLATE HEAT EXCHANGER
The Pillow Plate Heat Exchanger realizes thermal transfer through Embossed or Corrugated plates however, sealing is by means of welding and not through rubber gaskets. The distance or gap between each set Pillow Plates can be adjusted to create a Wide Gap / Free Flow on the fouling side.
Compared to other types of Plate Heat Exchangers, the Pillow Plate Heat Exchanger has some unique features and advantages, especially for fluids containing impurities or high viscosity or for complex applications. In the below chart, you find various applications in which the Pillow Plate Heat Exchanger would be a good consideration.
