heat exchanger
A heat exchanger is a device used to transfer heat between two or more fluids without mixing them. It plays a vital role in heating, cooling, and energy recovery processes across industries like HVAC, power generation, oil & gas, and chemical processing. Heat exchangers come in various types such as shell and tube, plate, finned tube, and air-cooled, each designed for specific applications. They help improve energy efficiency, reduce operational costs, and maintain optimal system temperatures.
