Condenser is a device used to convert steam into liquid by cooling it down.

• Condenser works by transferring heat from the steam to a coolant, causing it to condense into liquid form.

• Common types of condensers include surface condensers and shell-and-tube condensers.

• Condensers are used in power plants, refrigeration systems, and air conditioning units.

• Efficient condensation is essential for maximizing energy efficiency and equipment performance.
