Dual Function Protection – Absorbs moisture and acid while filtering solid contaminants down to 100μm, protecting compressors from premature failure caused by ice blockages, acid formation, and particulate damage.
High Moisture & Acid Capacity – Mixed desiccant (molecular sieve + activated alumina) provides high static water absorption rate (≥20%), effectively removing moisture and acid from the refrigerant circuit.
Corrosion-Resistant Copper Body – Spun copper construction offers excellent corrosion resistance, making it suitable for coastal and marine applications where standard steel-bodied driers may fail.
Compact & Lightweight – Compact design with low weight minimizes space occupation and vibration load on piping, suitable for refrigerators, water dispensers, and compact HVAC units.
Welded ODF Connections – Full copper fittings allow clean, leak-free welded installation. Compatible with standard copper tubing and brazing alloys.
Stable Bulk Supply – Standard sizes ship in 15–25 days, supporting rolling replenishment and reducing inventory capital occupation.
OEM & ODM Support – Custom logo, packaging, and product labeling available. Can produce according to customer drawings or samples.
Batch Traceability – Each batch undergoes strict quality inspection.
Export Packaging – Seaworthy carton and pallet packaging, suitable for long-distance ocean shipping.
