What do filter dryers typically protect refrigeration systems from?

Filter dryers play a crucial role in refrigeration systems by specifically protecting them from dirt and moisture. In refrigeration applications, moisture can lead to the formation of ice in the system, which can obstruct the flow of refrigerant, cause corrosion, and lead to equipment failure. Dirt and debris can also contaminate the refrigerant, damaging components like valves, compressors, and evaporators.

By removing moisture and particulates, filter dryers help maintain the efficiency and longevity of the refrigeration system. They ensure that the refrigerant circulates clean and dry, which is vital for optimal heat exchange and overall system performance. This protection is essential in preventing significant operational issues and costly repairs, making filter dryers an integral component in ensuring reliable refrigeration operation.
