What is the purpose of a filter drier in a refrigeration system?

The purpose of a filter drier in a refrigeration system is to remove moisture and impurities from the refrigerant. This is critical because moisture can lead to ice formation inside the system, which can block refrigerant flow and cause significant operational issues. In addition, impurities such as dirt and debris can cause wear and tear on components, leading to system failure and reduced efficiency.

By keeping the refrigerant clean and dry, the filter drier helps maintain the overall health of the refrigeration system, ensuring that it operates effectively and efficiently. This protects the longevity of the components within the system, enabling more reliable cooling performance.
