DVAI manufactures pillow plated dished heads for your use in stainless steel vessels.  These heads are equipped by laser welded pillow plates according to your drawings for heating and cooling applications.

Pillow plate orders

After reception and validation of an order, the technical office designs a drawing presenting:

  • the shape of the two plates (metal base sheet and the pillow plate sheet)
  • the positioning of IN and OUT hole connections for heat transfer fluid
  • the welded spots pattern
  • eventual continuous welded lines for mastering the circuit


This drawing is submitted to the client for validation

Manufacturing starts immediately after the client’s agreement enabled by DVAI’s complete stock of plates as well as all the machines necessary for the cutting.

Pillow plates are delivered non-inflated along with the installation notice for the in and out connections and helpful advice for inflating and eventual repairing.
