Pillow Plates
Pillow plate thermoplate heat exchangers
What is a Thermoplate?
A pillow plate is a fully welded heat exchange plate. The plate consists of two plates that are spot-welded together. The plates are sealed with a welded seam along the contours of the plates. The plate is finally expanded until the desired expansion height is achieved. The expansion height is the maximum space between the two plates.
Pillow plates(thermoplates) and Dimple plates are similar products both made from stainless, but they also have distinct differences. The Dimple plate are a preformed plate to be attached to the final form afterwards. The pillow plates are included in the design before the final form. The dimple plates can be used for existing equipment, but only allows for a pressure below 6 bar. The pillow plate design allows for higher pressure.

Benefits of resistance welding
This is of course only true when the resistance welding is conducted correctly. We at ATHCO-Engineering A/S have more than 40 years of experience with the resistance welding for thin materials.
No add material to weld
Limited pollution of the metal sheets.
The corrosion and strength of the materials are maintained.
No visible welding seems
Hence no nucleated spots for fouling, corrosion and freezing.
No crevice – highly susceptible for corrosion.
Only a low heat input at the welding spot
The strength and corrosion resistance of the heat-affected zone is nearly that of the parent material.
No space behind the welding
No risk of corrosion in between the weld metal sheets.
Product advantages
- Very easy to clean (high sanitary standard).
- Efficient heat transfer because of large surface area to volume ratio.
- Compact design and simple installation.
- Good thermal operation efficiency due to high heat transfer coefficients.
- Each heat exchanger is individually designed for the heat load, flow rate and pressure drop limitations of the specific application.
- Self-cleaning effect due to the smooth surface of the thermoplates.
- Fouling tendency is reduced to an absolute minimum, and that also applies to the need for maintenance.
- Energy-saving and greener solutions.
