Quality for all

RAUCELL ALL WELDED AND ALL STAINLESS PLATE HEAT EXCHANGER

  • Construction – Primary and secondary circuits and all surfaces of acid sustainable stainless steel, AISI316L.
  • Joints on the HE’s edge. No flowholes in the plates. Whole surface transfers heat.
  • The plates are welded together from the edge to form an outer shell. No ”Plate and Shell” cassette construction. No gaskets.
  • No joining points between the plates, which gather dirt. No dissolving, poisonous, intermediate copper or other aquatic brazing plates.

A structure for the end of pressure vessels, most applicably plate heat exchangers, for reducing the effects of movement changes and vibrations caused by variations in internal pressure and temperature. The end is made up of a heat transfer plate and an end part in such a way that the end part is connected by welding to the shell of the outer surface of the heat exchanger stack, forming an enclosed chamber on the end of the heat exchanger, into which chamber higher pressure than the external pressure level is brought and/or generated. The higher pressure receives and dampens, via a heat transfer plate, vibration and pressure shocks harmful to the heat exchanger structure in the medium circuits of the heat exchanger.
