copper structure is formed from high‑quality copper tubes with a smooth circular arc design, providing excellent resistance to pressure and . A built‑in molecular sieve absorbs water for effective drying, while filter nets installed at both ends capture debris. High‑quality material design uses copper housing filled with molecular sieve particles that easily absorb moisture and acidic harmful substances in the refrigerant. At the same time, internal filters trap fine particles and other contaminants to maintain clean refrigerant circulation. Wide application range makes this dryer suitable for refrigerators, freezers, and air conditioning tanks in household or light commercial refrigeration equipment. It is an ideal replacement for damaged or aging filters, restoring system efficiency while helping extend service life. Molecular sieve drying filter is a key component in refrigeration systems, responsible for dehydrating and filtering refrigerant to remove moisture and impurities. By preventing ice clogging and dirty blockage in the pipeline, it helps keep the refrigeration circuit clear and stable, ensuring your refrigerator or cooling unit operates efficiently. Main function of the refrigerator filter dryer is to prevent blockage caused by dirt, metal shavings, or ice crystals in the refrigerant cycle, thus protecting capillary tubes and expansion devices.
