Plate Heat Exchanger

The brazed plate heat exchanger is composed of a number of standard wear-resistant stainless steel plates and high-purity brass plates (or nickel plates) which are pressed into a herringbone corrugation, and then vacuum brazed. The grain direction of adjacent plates is opposite, and the corrugations and ridges intersect each other, forming a large number of contact welds, which are formed by vacuum brazing, thus forming a complex flow channel unit in the heat exchanger, allowing cold and hot fluid to flow . The whole equipment has no gasket and no outer frame, forming a compact plate heat exchanger, and has high heat transfer efficiency, and can withstand continuous high temperature (high temperature resistance of 250 degrees) and high pressure (high pressure 45bar) operation. Less liquid stagnation, easy installation, light weight, maintenance-free, economical and energy-saving

Feature: 

1.Thin plates. High heat transfer coefficient and less stagnation.   
2.Low water consumption.  1/3 compared to the tubelar heat exchanger under same working condition.            
3. Low fouling factor. Reducing the  cleaning cycle.            
4.Light weight.  20%-30% compared to tubelar heat exchanger.   
5. Withstands high temperatures (250 ° C) and high pressure (45 BAR), reduces corrosion issues            
6. High performance.
