The pillow plate consists of two stainless steel sheets that are laser welded together by welding a custom circle weld pattern. The outside perimeter of the pillow plate is fully laser welded to create a pressure boundary at the edges of the pillow plate. A counter is welded to create the pressure-tight part. The pillow plate is hydraulically inflated by using water through a hydrostatic pump. The inflation process pressurizes the two sheets which allow the material to deform and a cavity will be created for use as a heat transfer medium. The pillow plate can be used either as liquid, stem or refrigerants.
Cost-effective due to low welding costs
Reduced deposition (algae, lime, etc) due to higher turbulence (less fouling)
Thinner materials can be used, saving you on materials costs.
Due to the low volume in the plate, little cooling / heating fluid needs to be circulated.
as a result, less pump capacity is required.
