INTERIS is a pioneer of the dehydration technology based on molecular sieves. The company owns many patents, which are real standards in the fuel bioethanol / dehydrated ethanol production.

Our reputation is based on the reliability of our units, especially the lifetime of the zeolites lasting more than 10 years.

Design of molecular sleeves dehydration systems allows a perfect integration of the dehydration unit in the distillery, achieving higher performances and lower vapour consumptions.
