A condenser is a heat exchanger used to condense a substance from its gaseous phase to its liquid phase by cooling it. Condensers are widely used in various industries, including refrigeration, air conditioning, and power plants, to remove heat from steam or refrigerant gases and convert them into liquids for reuse. Designed for efficiency, they help maintain system performance by efficiently transferring heat and maintaining operating temperatures. Depending on the specific needs, condensers are available in various types, including air-cooled, water-cooled, and shell and tube configurations, offering flexibility for different industrial applications.
