Many plant processes require heat exchangers to transfer energy from one fluid or gas to another without mixing them together. Being essential parts of both comfort and process heating and cooling applications, heat exchangers perform efficiently for a long time without much thought.
Plate heat exchangers are one of the most popular types due to their efficiency and versatility. Made up of two metal end plates that envelop many thin metal plates located in close proximity, a liquid is pumped into one side of the plates and another liquid is pumped into the other side. As both liquids contact as much surface area as possible, heat is exchanged from one liquid to the other liquid.
