Brazed plate heat exchanger PB

air/oilcoppernickel

Plate-type exchangers are made of corrugated stamped plates. The plates have a 180° orientation in order to create a grid. Fluids are normally routed in a counter-flow pattern. Plates are fused together using a brazing material with a lower melting point that the plate, itself this is normally copper or nickel.The brazing takes place in a vaccum furnace resulting in a robust long lasting joint. The corrugated surface on the plates creates good turbulent flow to maximise heat exchange and reduce fouling. Benefits of brazed plate coolers: ▪ High coefficient of heat exchange; ▪ Reduced dimensions and high performance; ▪ High pressure and temperature resistance; ▪ Easy installation Advantages of Brazed Plate Heat Exchangers ▪ high heat transfer coefficient ; ▪ small unit size with high heat transfer capacity ; ▪ high resistance to pressure and temperature fluctuations ; ▪ stainless steel connections ; ▪ easy installation ; Brazed plate heat exchangers consist of stainless steel plate packs, which have embossed chevron patterns. The plates are turned 180°to each other, causing the plate ridges to intersect, and creating a lattice of intersecting channels. The fluids can flow in countercurrent or co-current way. The entire construction is sealed together by the means of brazing in a special vacuum furmace. Special corrugation pattems promotes high turbulence flow. Turbulence dramatically improves heat transfer rates and reduces the amount of deposits inside the unit.
