Heat Exchangers Spares

Types of Plate Heat Exchangers Type Description Common Use Gasketed Plate Uses rubber gaskets to seal plates. The major advantage is that the stack can be easily opened for cleaning, inspection, or adding/removing plates to change capacity. Most common type. Used in chillers (as evaporators/condensers), domestic hot water systems, and food/beverage processing. Brazed Plate The plate pack […]

Advantages of Plate Type Heat Exchanger Plate Heat Exchanger (PHE or PHEX) is a highly efficient type of heat exchanger that uses multiple, thin metal plates to transfer heat between two fluids.  How It Works The fundamental principle is simple: two fluids at different temperatures flow on opposite sides of a thin metal plate. Heat is […]

Brazed Plate Heat Exchanger – How It Works The operating principle is identical to other plate heat exchangers but in a more robust package:

What is a Brazed Plate Heat Exchanger? A BPHE is constructed from multiple thin, corrugated metal plates (typically stainless steel) stacked together. Unlike a gasketed plate heat exchanger, a BPHE has no rubber gaskets or a frame. Instead, the entire plate pack is assembled and then placed in a vacuum furnace where a brazing material […]

Types of Evaporators Evaporators are classified based on two main criteria: How they are constructed and 1. Classification by Construction & How Fluid is Cooled A. Shell and Tube Evaporator This is the most common type in water chiller systems. It consists of a cylindrical shell (a large pressure vessel) with a bundle of tubes inside. B. […]
