Specialty heat exchangers play an important role in a wide variety of industrial applications; these devices transfer heat from one medium to another, and are used for a diverse range of heating and cooling processes. From power generation to food and beverage to pharmaceuticals, heat exchangers can be found everywhere. While choosing a one-size-fits-all heat exchanger for your specific application may seem like a cost saving decision, it can actually lead to disastrous consequences in the long run for your equipment and operators. In terms of safety and performance, it is absolutely crucial to select the correct exchanger for your application. This choice will be determined by several factors, including amount of heat needed to be exchanged, thermophysical properties of the process and fluids, temperature of fluids, pressure and flow rate, and more. This white paper outlines and defines the various types of heat exchangers, and also provides an overview on certifications and materials.
