Purge units on centrifugal chillers removes?

Purge units on centrifugal chillers are designed to remove non-condensable gases, such as air and moisture, from the refrigerant system. These gases can compromise the efficiency of the chiller by reducing heat transfer and increasing energy consumption. By continuously monitoring and venting these gases, purge units help maintain optimal performance and prolong the life of the chiller. This process ensures that the refrigerant remains as pure as possible, enhancing overall system reliability.
