Welded Copper Filter Drier for Refrigeration Parts – High-Efficiency Moisture & Acid Removal
Product Overview
The Welded Copper Filter Drier is a key protection component for refrigeration and air-conditioning systems, designed to remove moisture, acid, and impurities from refrigerant circuits.
By filtering solid particles and adsorbing moisture, this filter drier prevents ice formation, protects the compressor, and ensures stable operation of the entire system.
Its all-copper welded body provides excellent corrosion resistance, reliable sealing, and long-lasting durability, making it ideal for commercial refrigeration, household refrigerators, heat pumps, and small air-conditioning equipment.
Product Features & Advantages
- Superior Filtration & Drying - High-quality molecular sieve core efficiently absorbs moisture and acid from the refrigerant.
- All-Copper Construction - Seamless copper shell provides excellent corrosion resistance and ensures reliable brazing connections.
- Strong Leak Resistance - Precision welding technology guarantees tight sealing and long service life under high pressure.
- Wide Refrigerant Compatibility - Suitable for common refrigerants such as R134a, R600a, R404A, R22, R410A, R32, and more.
- Compressor Protection - Prevents acid formation and contamination, extending compressor life and reducing maintenance costs.
- Flexible Installation - Available in various sizes and connection types to meet OEM and replacement needs.
Installation & Usage Guidelines
- System Preparation
- Evacuate and discharge the refrigeration system before installation.
- Clean the piping and ensure no debris remains in the circuit.
- Brazing Installation
- Connect the copper filter drier by brazing to the liquid line according to the system's flow direction (marked by an arrow).
- Use nitrogen during brazing to prevent oxidation inside the tube.
- Testing & Operation
- Conduct a leak test and vacuum dehydration before recharging the refrigerant.
- Replace the filter drier whenever the system is opened for maintenance to maintain optimum performance.
