Molecular sieve

Molecular sieve-3A
¡¡¡¡           
The pore size of 3Amolecular sieve is 3A.It does not adsorb any molecular larger than 3A.According to the industrial application specialties ,we endue our products with the characters of higher adsorption speed ,stronger crushing and anti-contaminative resistance ,more cyclic times and longer work-span .All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying ,refinery polymerization for cracked gasses ,ethylene ,propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.

Molecular sieve-5A

¡¡¡¡The pore size for 5A molecular sieve is about 5A. It can adsorb all kinds of molecular smaller than this size, it is mainly used in separation of the normal and isomerous alkane; pressure swing adsorption(PSA)for gases; co-adsorption of moisture and carbon dioxide. Based on the industrial application specialties, we have produced out our own PSA molecular sieve products, which have better selective adsorb ability and more rapid adsorption speed, being the elaborated products, it could suitable for gases generation and concentration PSA plants of any sizes and any types in the world.

Refrigerant desiccant¡¡¡¡                   The life span of freezer system is mainly determined by the refrigerant leakage time ,this was caused by harmful substances produced from trace moisture and refrigerant reaction. Molecular sieve is the most powerful product to removal trace water .Our molecular sieve are designed to protect the refrigerant dew point in a much professional way .The technical requirement for refrigerant molecular sieve .The molecular sieve should adsorb noting except water .The molecular sieve should not react with of effect the stability of refrigerant .Require very low dew point control .Require very low abrasion ¡¡¡¡So ,refrigerant need specialized molecular sieve desiccant ,our molecular sieve XH-7is suitable for some very stable refrigerant such as R-134,and the type XH-9 can suit for any refrigerant.Technical parameter:Refrigerant desiccantItem Unit XH-7 XH-9
