Zeolite molecular sieves are widely adopted desiccants for refrigerants and play an indispensable role in the dehydration of refrigeration systems. They fit most refrigerant filter equipment, covering heat exchanger filters used in refrigerators, freezers, air conditioners and other refrigeration devices.
Why Refrigerant Desiccants Are Necessary
Moisture inside refrigeration systems reacts with refrigerants and triggers refrigerant hydrolysis. This process produces corrosive substances like hydrogen chloride and hydrogen fluoride, which erode system components including compressors, pipelines and valves. Additionally, residual water freezes easily, forming ice clogs in pipelines and valves. These blockages weaken cooling efficiency and may even trigger complete system breakdowns.

Molecular Sieve Functions In Refrigerant Filters
- Prevent Ice Blockages
Zeolite molecular sieves efficiently and selectively adsorb water molecules without absorbing refrigerant molecules. This property eliminates ice formation and blockages that occur amid sudden temperature drops in refrigeration cycles.
- Stop Metal Corrosion
These molecular sieves trap system moisture, solid impurities and corrosive byproducts from hydration reactions. This protection shields all metal components within refrigeration systems from corrosive damage.
- Preserve Refrigerant Purity
Molecular sieve desiccants remove residual moisture and contaminants from refrigerants. This maintains the chemical stability of refrigerants and avoids component decomposition or performance deterioration caused by moisture contamination.
- Protect Overall System Components
Refrigerant filters capture wear debris from compressor operation and residual contaminants left during equipment installation to prevent pipeline clogging and valve failure. Meanwhile, zeolite desiccants ensure smooth refrigerant circulation, effectively avoiding high-pressure alarms and compressor overheating issues.
Molecular Sieves For Refrigeration Dehydration
- XH-5 Zeolite Molecular Sieve
As a foundational refrigerant desiccant model, XH-5 features high water adsorption capacity and thoroughly removes trace moisture from refrigerant systems. Its outstanding chemical stability and broad refrigerant compatibility make it suitable for most conventional refrigerants.
- XH-7 Zeolite Molecular Sieve
This upgraded version of the XH-5 desiccant delivers superior acid adsorption performance and drastically reduces corrosive contaminants in refrigeration systems. XH-7 also boasts excellent thermal stability and high mechanical strength, adapting well to harsh working conditions such as high-pressure cyclic operation.
- XH-9 Zeolite Molecular Sieve
XH-9 maintains stable structural performance under extreme thermal and chemical stress. Besides high water absorption and premium acid adsorption capabilities, its exceptional fracture resistance meets the long-term durability demands of high-pressure refrigeration systems.
- XH-11 Zeolite Molecular Sieve
XH-11 works well with various mixed eco-friendly refrigerants and achieves effective dehydration without disrupting the proportional balance of refrigerant components. It stands as the preferred desiccant for refrigeration systems that operate under high pressure and high temperature conditions.
