Heat Exchanger: How to Select the Right One

Apr 19, 2021 · Consider phasing. Heat exchangers fall into two basic categories based on the fluids (liquids or gases) being processed. Single-phase heat exchangers process only one phase--liquid or gas; Two-phase heat exchangers can be used to boil liquid into a gas. Such units are sometimes called boilers.

What Are The Different Types of Boilers

Dec 30, 2021 · A heat exchanger is a system that is very important for transferring heat from one medium to another (liquid, vapor, or gas). Heat exchangers are used in both situations where cooling or heating is required. According to the type of heat exchanger used, the heat transfer process can be carried out as gas to gas, liquid to gas, or liquid to liquid.
