What is a Heat Exchanger?
A heat exchanger is equipment used to transfer heat from one fluid to another without mixing them. It is commonly used with liquids, gases, and vapors in industrial processes. Heat exchangers are available in different designs to suit various applications. Depending on the type, they can transfer heat between liquid-to-liquid, gas-to-gas, or liquid-to-gas systems through a solid surface.
We produce a wide range of heat exchangers to meet diverse heating and cooling needs across various industries.
