Should cleaning still be necessary, learn more on about CIP ( Cleaning-in-place).Thanks to the printed circuit technology, an Alfa Laval HyBloc TM heat exchanger is 85% smaller than a comparable shell-and-coil or shell-and-tube heat exchanger. The turbulent flow in the heat exchanger has a self-cleaning effect. The brazing material is made of pure copper. The plates and connections are made of stainless steel. The corrugation of the plates is specially designed to induce maximum turbulence and even distribution of both the fluid flows in order to make heat transfer as efficient as possible. The transfer of heat energy from one fluid to the other takes place over the large surface. The two fluids flow in alternate channels in a counter-current flow pattern in order to achieve the most efficient heat transfer. Working principleĬhannels for the fluids are formed between the plates. Pressure peaks and rapid temperature cause substantial physical stresses within the materials, and Alfa Laval’s research has focused on the details of these phenomena in order to ensure designs that are extremely resilient and provide a long service life. Brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates. The plate design guarantees the longest possible life. The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. DesignĪ brazed plate heat exchanger consists of thin, corrugated stainless steel plates, stacked into a plate package and brazed together with pure copper. Heat transfer technology involves bringing two substances at different temperatures close to each other so that one either heats or cools the other.
