Desiccant Usage Calculation

How to Accurately Design Drying and Moisture Control Solutions

Developing drying and moisture control solutions that suit different environmental conditions is crucial. A scientific method for calculating the appropriate desiccant dosage is one of the foundational steps for the success of desiccant products and ensures customer satisfaction.

At Wisepac, we advocate for the use of scientific dosage calculation methods and encourage our customers to apply them in daily operations. This calculation model is designed based on the DIN 55474 standard issued by the German Standardization Institute for calculating the required units of desiccant within packaging.
