Plate Concepts Brazed Plate Heat Exchangers are custom designed to meet the specific needs of our clients. The type of brazed heat exchanger and the required number of plates are determined by duty requirements, fluid media, temperature profile, flow range and hydraulic conditions.   

Materials of Construction

Plates and connections are made of AISI 316 SS. Brazing material is either copper or nickel.   

Construction

Pressed metal plates are assembled in a plate pack with the chevron pattern reversed in every other plate. The ridges of the pattern intersect on adjacent plates - forming a lattice of contact points. Each adjacent pair of plates forms a channel. The stainless steel plates are then brazed with copper or nickel in a high temperature vacuum furnace.   

Operation 

The hot and cold media are in counter-current flow to each other in alternate channels. The plate pattern induces intense turbulence in the hot & cold passages - resulting in a high heat transfer coefficient and low fouling tendencies.
