Your Source for Molecular Sieve Desiccants

For over 40 years, Pioneer Air Systems has designed, manufactured, programmed, and maintained customized commercial compressed air systems to meet the specifications of our client’s needs. Our expert team works with your business to provide the right molecular sieve desiccants and prolong the life of your system.

What Are Molecular Sieves?

A molecular sieve is a material constructed from crystalline metal and interconnected with alumina and zeolite tetrahedral components. Sieves are perfect to use as desiccants and absorbents in industrial air systems. They allow for small pore sizes to pass and are efficient at blocking large molecules in complex systems. Molecular sieves have a strong adsorption capacity, breaking down carbon dioxide, oxygen, water, and other molecules with smaller pore sizes. Molecules of sieves are three-dimensional materials made up of elements like activated carbon, clay, silica dioxide, silica gel, and zeolite. Molecular sieves are available in beaded, pelleted, and powered variations.

Sieve desiccants are an excellent option to use for air dryers. The crystalline composition of molecular sieves makes the desiccant a perfect solution for absorbing water and other impurities to obtain pure liquid and gas for a compressed air system. A great way to reduce moisture from liquids and gasses is using molecular sieves for water removal.

Types of Molecular Sieves at Pioneer Air Systems

Different types of sieve desiccants are based on adsorption capacity, manufacturing and industrial needs, and other specific application requirements. Pioneer Air Systems is proud to offer four different types of molecular sieve desiccants:

3A Molecular Sieves

Almost all industries require 100% water-free ethanol for industrial and manufacturing uses within facilities. The adsorbent structure of 3A molecules showcases molecular sieve dehydration and water extraction through a variation of potassium-based pore sizes. 3A sieves are available in bead, pellet, and powder form. This molecular type has various applications for ethanol drying, insulating gas units, dehydration, ethane drying, and inert gas purification. Listed below are some benefits of utilizing 3A molecular sieves:

Easy and straightforward to use, reduces labor and training costs
No single type of chemical used throughout the process, no material handling or liability issues
Dehydration of ethanol-hydrated vapors and water vapors
Utilized as an individual system or a distillation system, flexible for maximizing efficiency
160 to 190-proof of ethanol

4A Molecular Sieves

4A molecular sieves are another variation used as desiccants, and they are constructed from sodium forms to make a Type A structure. 4A sieves have resistance quality, stronger adsorption rates, and reliable adsorption speeds. If you want to reduce humidity and remove moisture from liquids and gasses, Pioneer Air System’s 4A sieve is the option for your facility. Check out a few benefits of using 4A molecular sieves:

Vital for air drying
Ensures low dew points
Dehydration of electric components, ethanol, and unsaturated hydrocarbons
Drying of ammonia gas, air-filled insulated glass units, natural gas, petroleum gas, and refrigerants

5A Molecular Sieves

5A sieves tend to absorb molecules with reduced pore sizes. Our clients commonly use Pioneer Air System’s 5A solution to purify and separate natural gasses. 5A material is typically made from zeolite components, which are adept at adsorbing carbon dioxide, humidity, and moisture. You can also use this sieve desiccant to monitor composition, density, water content, and other chemical specifications. Pioneer’s 5A desiccants are available in beads and pellets and are most reliable for:

Swing adsorption of hydrogen and oxygen
Drying carbon dioxide, aromatics, moisture, PSA oxygen, and natural gasses
Removing carbon dioxide from cracked gas and hydrocarbons from refrigerants

13X Molecular Sieves

13X sieves from Pioneer Air Systems are constructed from zeolite and are available in bead and pellet material. This option is popular among clients for industrial gas and liquid drying, purification of components, and the removal of harmful substances. 13X molecular sieves are best for:

Pre-purification in cryogenic plants
Removing mercaptan from LPG gas
Perform drying of industrial gasses

Applications for Molecular Sieve Desiccants

Are you looking for the ability to control pore size consistency during industrial and manufacturing processes? Molecular sieves have excellent versatility for managing consistency and size throughout complex facility applications.

Carbon Dioxide Removal

Often considered an alternative method for carbon dioxide removal, molecular sieves act as effective adsorbents for liquids and gasses. Pioneer’s 3A and 4A sieve types are the top picks for carbon dioxide removal with the ability to adsorb air contaminants. Listed below are a few benefits of using our 3A and 4A molecular technology:

Contamination resistance
Consistent adsorption speed
High adsorption capacity and rate

Hydrogen Purification

Finding pure hydrogen on Earth is a rare event. Most hydrogen that is used is a combination of atoms and other molecules. Pioneer’s 5A molecular sieves help to sort hydrocarbons from each other for hydrogen purification.
