Molecular Sieve

Molecular sieve is a kind of crystallized aluminosilicate .it has the characteristic of even pore diameter and large surface areas, good thermal stability, large capacity of absorption, high intensity.Speical excellent features as selective absorption, It only absorbs the molecules of which the diameter is less than the pore size of the Molecular sieve.

Selective absorption for polar molecules and unsaturated molecules,The bigger polarity and unsaturated ratio, the stronger selective absorption.strong water absorption even in high temperature, large space velocity or low content of water, it has quite a large water absorption capacity.

Dohntec Molecular sieve has several types of 3A, 4A, 5A,5A small oxy-enrich,13X,13XACS, IG Desiccant, Refrigerant Desiccant according to its use.

3A Molecular Sieve
Product Name:
3A Molecular Sieve
Model:
DT-3A MS
Description:
Dohntec Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an aperture about 3 angstroms (0.3nm). It doesn't absorb any molecules larger than 3A,its used for absorbing water mainly.
4A Molecular Sieve
Product Name:
4A Molecular Sieve
Model:
DT-4A MS
Description:
Dohntec Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an aperture about 4 angstroms (0.4nm).It doesn't absorb any molecules larger than 4A, including propane. It absorbs water, methanol, ethanol, sulfureted hydrogen, sulfur dioxide, carbon dioxide, ethylene, propylene mainly.
5A Molecular Sieve
Product Name:
5A Molecular Sieve
Model:
DT-5A MS
Description:
Dohntec Molecular Sieve type 5A is an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an aperture about 5 angstroms (0.5 nm).It absorbs any molecules less than 5A. It is especially used in separation of the normal and isomerous alkane, Pressure Swing Absorption for gas, co-absorption of moisture and carbon dioxide.
5A Small Oxygen Enrichment Molecular Sieve
Product Name:
5A Small Oxygen Enrichment Molecular Sieve
Model:
DT-5A OEMS
Description:
Type 5A small oxygen enrichment molecular sieve is a kind of appropriative molecular sieve specially designed for medical or healthy oxygen generator – a mini PSA plant for medical application. The product has the feature of high purity of oxygen concentrating and long lifespan. It is already widely used in the medical care field.
13X Molecular Sieve
Product Name:
13X Molecular Sieve
Model:
DT-13X MS
Description:
Dohntec Molecular Sieve 13X is the sodium form of the type X crystal and has an aperture than the type A crystals. It absorbs any molecules less than 10A, mainly used as catalyst carrier, co-absorption of CO2 and H2O, co-absorption of H2O and H2S. It is used as desiccants for medical and air compressor.
13X Molecular Sieve for Air Separation
Product Name:
13X Molecular Sieve for Air Separation
Model:
DT-13X FAS
Description:
Type 13X ACS molecular sieve is specially designed to co-absorption of CO2 and H2O for air cryo-separation industry. It has large capacity and fast absorption rate for removal of CO2 and H2O to prevent the bed gelation, it is suitable for any size air cryo-separation plants.
IG Desiccant
Product Name:
IG Desiccant
Model:
DT-IG D
Description:
This insulating glass desiccant can deeply co-adsorb the resident moisture and organics in insulating glass, keep the IG clear and transparent even at very low temperature. Moreover, it does successfully avoid the tremendous uneven air pressure placed on the glasses, which is caused by seasons and day-night temperature changing.
Refrigerant Desiccant
Product Name:
Refrigerant Desiccant
Model:
DT-RD
Description:
The life span of freezer system is mainly determined by the refrigerant leakage time, the leakage is caused by the harmful substance corrosion which generating from the reaction of refrigerant and tiny moisture on the tube. Molecular sieve has the features of low dew point, high intensity, low abrasion loss and good chemical stability.
