Exhibition Overview
From November 3–6, 2026, ComVac ASIA (Shanghai International Compressor and Equipment Exhibition) will open at Shanghai New International Expo Centre. As a source manufacturer specializing in the R&D and production of adsorbent drying materials in China, Xintao Technology will showcase core products including molecular sieves, activated alumina, carbon molecular sieves, and ceramic balls at Booth M2, Hall N4. We sincerely invite industry customers and partners to visit us and discuss adsorbent solutions for compressor drying and purification.
Xintao Technology – 20+ Years Manufacturer
Xintao Technology has focused on adsorbent and separation materials for more than 20 years, specializing in the R&D, production, and sales of molecular sieves, activated molecular sieve powder, activated alumina, carbon molecular sieves, inert ceramic balls, and other products. With mature production processes and a complete quality control system, we provide customized gas drying and purification solutions for industrial customers. Our products have a complete range and stable performance and are widely used in petroleum, chemicals, electronic, environmental protection, gas separation, air purification, pharmaceuticals, new energy, metallurgy, and other industries.
In the compressor industry, moisture and oil impurities in compressed air are key pain points affecting downstream equipment stability, shortening pneumatic component life, and causing product defects. Xintao adsorbent materials are core packings for compressed air post-treatment drying systems:
Xintao Molecular Sieves:
Regular micropore structure, high adsorption capacity, and strong dew point control. Main models include 3A, 4A, 5A, and 13X by pore size. They deeply remove trace moisture from compressed air to achieve low-dew-point drying and are suitable for heatless and micro-heat regenerative desiccant dryers, ensuring stable compressed air quality. They can also selectively adsorb CO₂ and other impurities to meet the gas requirements of high-end air compressors and precision pneumatic equipment.
- 3Amolecular sieve: 0.3 nm pore size; preferentially adsorbs water and hardly adsorbs hydrocarbons or alcohols; suitable for special compressed gas drying with strict protection requirements for media components, avoiding material loss caused by co-adsorption.
- 4A molecular sieve: mainstream model for compressor desiccant dryers; 0.4 nm; efficiently adsorbs water and a small amount of CO₂ and other impurities; suitable for most general desiccant dryers.
- 5A molecular sieve: larger adsorption window; 0.5 nm; removes water and larger-molecule impurities such as n-paraffins; suitable for complex operating conditions and central gas supply systems with relatively high impurity levels.
- 13X molecular sieve: 1 nm; stronger comprehensive purification; removes water and deeply removes CO₂ and some organic hydrocarbon impurities; mainly used for pre-treatment before cryogenic air separation and high-purity gas scenarios; preferred for equipment with stringent compressed air purity requirements.
Xintao Activated Alumina
After pre-filtration, compressed air may still carry a small amount of liquid condensate. Direct contact with molecular sieves can easily cause pulverization and permanent failure. Activated alumina desiccant preferentially intercepts most liquid water and emulsified oil, acting as a buffer filter to protect the upper molecular sieve layer, greatly extending the overall service life of the adsorbent bed and reducing equipment maintenance and replacement costs.
It can be used alone for general industrial gas drying or combined with molecular sieves in composite beds: activated alumina for coarse dehydration and molecular sieves for deep dehydration; it can also remove CO₂ and H₂S, balancing cost-effectiveness and low dew point. It is a cost-effective packing for compressor post-treatment equipment.
Xintao Inert Ceramic Balls
Inert alumina ceramic balls are dedicated support and buffer packings for drying towers, adsorption towers, and catalytic towers. They are chemically inert and do not participate in adsorption reactions. A high-alumina ceramic ball layer at the bottom of the adsorption tower mainly serves three functions: first, load bearing—dispersing the weight of upper activated alumina and zeolite molecular sieves and preventing fine adsorbent particles from being crushed and blocking the bottom filter; second, gas distribution—breaking up high-speed compressed air entering the tower, eliminating maldistribution and channeling, and allowing gas to pass uniformly through the entire adsorbent bed to fully utilize adsorbent capacity; third, buffering airflow impact—reducing erosion wear of the adsorbent and further lowering the probability of pulverization.
Xintao offers low-alumina ceramic balls, medium-alumina ceramic balls, and high-alumina ceramic balls in complete specifications. For compressor desiccant dryer conditions, medium alumina balls and high-alumina balls are preferred: high compressive strength, good thermal shock stability, resistance to temperature and pressure fluctuations, no cracking or shedding during long-term operation, effectively ensuring stable long-term operation of the drying system and reducing unplanned downtime caused by bed failures.
The complete adsorbent packing combination helps compressor post-treatment equipment stably output clean, dry compressed air, reducing pipeline corrosion, pneumatic valve failures, and coating/processing product defects, helping enterprises reduce energy consumption and maintenance downtime and improve production stability.
At ComVac ASIA, Xintao Technology will display samples of various adsorbent packings and provide selection consultation and customized operating-condition solutions for different desiccant dryers. Our on-site technical team can recommend suitable packing combinations based on customers’ air compressor capacity, pressure dew point requirements, and regeneration process.
