This device employs refrigeration technology to condense moisture within compressed air into liquid form, subsequently expelling it from the system. The result is a supply of dry and pure gas, contributing to extended equipment lifespan and enhanced operational efficiency.
Compressed Air Entry: Compressed air generated by the compressor typically carries a significant amount of water vapor due to the compression process, causing an increase in the concentration of moisture in the air.
Pre-Cooling: Initially, the compressed air entering the dryer is directed to a cooler, where it is cooled to approximate ambient temperature. This aids in more effectively condensing moisture in subsequent steps.
Compression After Cooling: Following pre-cooling, the air is recompressed, raising its temperature and pressure once again.
Condensation: Subsequently, the cooled compressed air is directed to a condenser, usually containing a refrigerant. This refrigerant absorbs heat from the compressed air, leading to the condensation of water vapor in the air into liquid water.
Moisture Separation: The cooled compressed air and the condensed liquid water are separated, often through a drain valve that expels the liquid water from the system.
Reheating: After the removal of condensed water, the dried air passes through the condenser for reheating, elevating its temperature to near the initial level. This ensures that the output dry air is not excessively cold.
Outlet: Ultimately, the dried compressed air exits the dryer through an outlet, ready to be supplied to equipment or applications requiring dry air.
