Common Heat Transfer Equipment and Their Functions 1. Cooler – Lowers the temperature of process fluids (liquid or gas) by transferring heat to a cooling medium like water or air. 2. Condenser – Converts vapor into liquid by removing heat, commonly used in distillation and refrigeration systems. 3. Vaporizer – Heats a liquid to produce vapor, used in processes like fuel gas conditioning and cryogenic applications. 4. Evaporator – Removes water or solvent from a solution through evaporation…
