MSDU Systems

Molecular Sieve Dehydration Units

Wintek’s molecular sieve dehydration units (MSDUs) utilize surface adsorption via molecular sieve beads to dehydrate alcohols and other solvents. Additionally, drying wet gas streams use our MSDUs. Our MSDUs are able to overcome limitations faced by conventional distillation, such as azeotropes, and frequently use less energy. This is because molecular sieve dehydration utilizes physical separation, rather than thermodynamic separation. The sieve beads remove and trap water molecules within them to achieve separation from the product. Using our expertise in vacuum technology, process vacuum systems then remove the entrapped water and regenerate the drying capabilities of the sieve beads.

Wintek offers custom designed, pre-packaged and pre-piped units for both Liquid Phase and Gas Phase adsorption. We work with your process parameters to design the appropriate system for your needs. Our patented MSDU designs allow for continuous product dehydration, which yield consistent dryness levels.

Wintek has MSDUs in operation internationally dehydrating ethanol, methanol, isopropyl alcohol and others. Our expert engineers offer on-site start up and trouble-shooting advice whenever needed.
