Pillow plate is in 2 types single and double embossed. welded with fiber laser,
It is widely used in heating/cooling/evaporation/condensation field which are necessary adapted in heat exchangers,tanks as milk ,beer,wine storage,fermentation ,falling film chillers,jacked vessels,evaporator plates,building roof,ice room etc.
Suitable for irregular shape, high pressure, high temperature or corrosive environment.
Process Type
- Two sheets of steel are overlapped and welded by laser. Laser ring welding is used in the middle of the sheet and two laser welding seals are used around the edge.
- Injecting high-pressure liquid between plates makes the plates expand and deform under pressure, forming a hollow plate heat exchanger with uneven surface.
Advantages of pillow plates:
· Less chance of leaks due to high quality welding.
· Higher heat transfer coefficients at lower flow rates.
· High efficiency in energy transfer/ dimple patterns enable better flows resulting in high-energy efficiency.
· Pillowplate is integrated in the structure, giving it extra strength.
According to the application any design is possible.
