Hygroscopic materials have an affinity for water and are sensitive to high relative humidity. Moisture regain by some of these materials causes them to become sticky and to not flow freely causing catastrophic problems in candy making, materials conveying, pharmaceutical and vitamin tablet making and packaging.
In other cases, when moisture is introduced into the process, product quality suffers such as in pharmaceutical and semiconductor clean rooms, laminated glass manufacturing and precision color printing.
Bry-Air, Inc. desiccant dehumidifiers are used to control the moisture content of the air in the manufacturing process thus ensuring reliable operation and product quality.
Both desiccant dehumidifiers and mechanical refrigeration systems can remove moisture from the air, so the question is which type is best suited for a given application? To explore a few applications related to moisture regain prevention please take a look at our case studies.
