NORGREN /NORGREN HERION / HERION WD2D WD2D

The WD2D filter drier is a component designed to remove contaminants, moisture, and impurities from refrigerant systems in HVAC and refrigeration applications. It plays a critical role in maintaining the efficiency and reliability of refrigeration systems by ensuring the purity of the refrigerant circulating through the system. The filter drier consists of a cylindrical body filled with desiccant material, typically activated alumina or molecular sieve, which adsorbs moisture and traps solid particles and acids present in the refrigerant. This helps prevent corrosion, blockages, and damage to system components such as compressors, expansion valves, and evaporators. The WD2D filter drier is installed in the refrigerant line, usually between the condenser and the expansion valve or evaporator, to effectively remove contaminants and moisture from the refrigerant before it enters critical components of the system. Regular replacement of the filter drier is essential to ensure optimal performance and longevity of the refrigeration system.
