Condenser A Condenser is a heat exchange device used to convert vapor or gas into liquid by removing heat. It is a key component in systems such as refrigeration, air conditioning, power plants, and chemical processing. In a typical operation, the vapor enters the condenser, where it comes into contact with a cooling medium (such as air or water). As heat is transferred from the vapor to the cooling medium, the vapor condenses into a liquid, which is then collected for further use or disposal. C
