Wholesale Aluminium filter drier Supplier, Factory

The Drier Filter is composed of copper pipe, molecular sieve and two filter devices and installed in the refrigeration system to absorb water and filter impurities.

Product Description

Molecular sieve

Molecular sieve is a synthetic compound with microporous cubic crystal hole structure, which can absorb residual water in refrigeration system and allow refrigerant to pass through normally.

Core characteristics

The main function of the drying filter is to remove moisture and impurities from the system, prevent ice blockage and dirt blockage, and protect key components such as compressors. Red copper material may have better corrosion resistance and thermal conductivity, which is one of its advantages. The red copper drying filter plays a crucial "guardian" role in the refrigeration/air conditioning system. Its core functions include:

Deep water removal

The residual moisture in the system is rapidly absorbed by internal adsorbents (such as molecular sieves) to prevent water from freezing and forming "ice blockage" in low-temperature environments, ensuring the smooth circulation of the refrigerant.

Precision filtration

The double-layer filter screen structure can intercept solid impurities such as welding slag and metal shavings, prevent the compressor from getting stuck in the cylinder or the throttling components from being blocked, and extend the service life of the equipment.

Long-term protection

Red copper material has excellent corrosion resistance and can resist the chemical erosion of refrigerants and refrigeration oil, ensuring long-term stable operation.

System adaptation

The unique design can balance the flow rate and pressure drop of the refrigerant, achieving efficient purification while reducing energy loss. It is particularly suitable for precision systems such as inverter air conditioners.

Its working principle is like installing a "double protective shield" for the system: the physical filter layer intercepts visible impurities, and the chemical adsorption layer eliminates the threat of hidden moisture, jointly building a clean and stable operating environment.

Frequently Asked Questions
Q1: What is the main function of the molecular sieve in the filter drier?
A1: The molecular sieve is a synthetic compound with a microporous structure designed to absorb residual water within the refrigeration system, preventing ice blockage while allowing the refrigerant to pass through normally.
Q2: How does the filter drier improve cooling efficiency?
A2: By removing moisture, acids, and solid impurities like welding slag, it reduces overall system resistance, prevents blockages, and improves the circulation efficiency of the refrigerant.
Q3: Can these filter driers be used for commercial equipment?
A3: Yes, they are highly versatile and widely used for maintenance, repair, and upgrades in domestic refrigerators, commercial freezers, car air conditioners, and industrial refrigeration equipment.
Q4: What materials are used to ensure the durability of the filter drier?
A4: The drier features a high-purity aluminum pipe shell that is rust and high-pressure resistant. The inner core contains a 3A molecular sieve paired with an activated carbon layer, sealed via argon arc welding to prevent leaks.
Q5: How does the copper material benefit the refrigeration system?
A5: Red copper provides excellent thermal conductivity and corrosion resistance. It effectively resists chemical erosion from refrigerants and refrigeration oil, ensuring the long-term stable operation of the system.
