PILLOW PLATES

- One Plate, Infinite Possibilities.
What are Pillow Plates?

Pillow Plates are a type of heat exchanger plate made by welding two thin metal sheets together—typically using laser welding in a custom pattern—and then inflating them with high pressure to create a pillow-shaped, dimpled structure. This forms internal flow channels and an enlarged surface area for efficient heat transfer.


Pillow Plates can be used individually or integrated into various equipment such as tank jackets, ice water banks, immersion-type chillers, or cooling walls.
Why Use Pillow Plates?

Pillow Plates are designed to address challenges faced by conventional heat exchangers in applications where space is limited, surfaces are irregular, or hygiene and energy efficiency are critical. They are especially popular in industries like food and beverage, pharmaceuticals, chemical processing, and energy recovery systems. Pillow Plate Heat Exchangers (PPHE) are the ideal choice for applications involving heat recovery from highly contaminated exhaust gases—such as those from incinerators or glass factories—or for indirect heat exchange with challenging fluids that are oily, sticky, dusty, abrasive, or contain heavy sediments. In such cases, traditional heat exchangers with finned or smooth tubes are often unsuitable.

  Advantages Description
  High Heat Transfer Efficiency Inflated pattern creates turbulence-enhanced flow, better thermal performance
  Hygienic & Easy to Clean Smooth stainless steel surfaces are CIP-friendly and free of dead zones
  Compact & Space-Saving Ideal for tight installations or integration into existing vessels
  Flexible Customization Fully customizable in size, shape, dimple depth, and welding pattern
  Low Maintenance No gaskets, fewer failure points, and long service life
  Withstands High Pressure & Temperature Laser-welded construction is robust for demanding applications
  Energy Efficient Improved thermal performance leads to lower energy consumption
Single Embossed
  • Single embossed Pillow Plates are constructed from two stainless steel sheets with differing thicknesses. To ensure surface flatness on the product side, a thickness ratio of 1:3 is required. The flat side makes these plates ideal for hygienic and sanitary applications. Thanks to a precise welding process, we ensure no heat tint forms during fabrication. Single embossed Pillow Plates are primarily used as vessel shells, bottom plates, and components across a wide range of applications in the process industry.

    • Pharmaceutical
    • Alimentary applications
Double Embossed
  • Double embossed Pillow Plates are made from two stainless steel sheets of similar thickness. Upon inflation, both sides of the plate expand, as surface flatness is not necessary for these applications. This type of plate is ideal for:

    • Immersion systems
    • Clamp-on applications
    • Heat recovery banks
