Product Description

Super Dryer 4a Molecular Sieve Desiccant For Electronic Products




Products such as semiconductors, circuit boards and various electronic and photoelectric components are particular about the environmental humidity while in storage and use. Moisture will easily lead these products to lose quality or even be damaged. 4A Molecular sieve desiccant can deeply adsorb moisture and improve the safety of storage.

The interval value of the indexes above are on the basis of the different grade of Molecular Sieve 4A





1.  4A Molecular Sieve used for purification of argon.
2. 4A Molecular Sieve for deep drying of gases and liquids.
3. 4A Molecular Sieve dehydration in the industries of paint, dye and coating.
4. 4A Molecular Sieve static drying in medicine packaging.

5. 4A Molecular Sieve especially used in the dehydration of automotive air system.




Xi'an Lvneng molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 4A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.



To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
