Hengye has considered the conditions that dehydration units need to operate at peak performance and designed a molecular sieve with ideal physical and chemical properties. Hengye’s specialized molecular sieve offers efficient performance, superior selectivity, and durable strength to maximize production, increase efficiency, and provide a favorable return-on-investment.


Ethanol Dehydration Units
•  3A molecular sieve
•  dehydration to less than 1% water
•  helps create fuel-grade ethanol
•  ideal physical and chemical properties:
—  strong crush strength
—  high adsorption capacity
 superior selectivity for water over ethanol

These combined properties makes our product highly efficient and productive while also offering a long lifespan. Our team will help optimize your dehydration units and train staff on proper care, maintenance, and damage prevention.

Our manufacturing process has received ISO 9001:2015 Certification for Quality Management Systems, which helps us continuously improve our techniques. Ask to see a Certificate of Analysis from one of our recent production lots.


Our team can help calculate your current efficiency and demonstrate how our products can save you money. The superior selectivity of EthaDry for water over ethanol allows more water to be adsorbed per cycle while decreasing the amount of ethanol recycled in the regeneration step.


From bed sizing to end of life, we will be there each step of the way to help increase the success of your operations. We are here to support the Ethanol Community, whether a quick question over the phone or on-site support is needed, we aim to help make your operations run smoothly.


EthaDry is manufactured to increase the efficiency and productivity of Ethanol Dehydration Units, while being offered at reasonable, direct-from-manufacturer pricing. Ask about drop-ship orders for additional savings.
