  • How does the  condenser work?

    How does the condenser work?

    A condenser works by passing gas through a long tube (usually coiled into a solenoid), allowing heat to be lost to the surrounding air. Metals such as copper have strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks wit...
