The principle is that a thin plate is laser welded on a thicker base plate. After completion of the tank itself, the thin plate is inflated with water or compressed gas (30-60 bar) to form the heat-exchanger. Then the in- and outlets are welded on the heat-exchanger.
Single embossed pillowplate can also be used as flat cooling plate under a transport conveyor to cool the product. (food and bakery applications)
A good relation between the sheet thicknesses is 1:3. this means for example:
- 0.8 - 2 mm
- 0.8 - 2.5 mm
- 1.0 - 3 mm
- 1.2 - 4 mm
- 1.5 - 5 mm
Through this design the base plate remains flat with a good inflated thin plate.
