When it comes to drying pharmaceutical products, three major variables viz., temperature, air velocity and absolute humidity play a key role. Since most of the pharmaceutical products are temperature sensitive the best way to attain optimum production and ensure efficient drying is to reduce the humidity.

This can be best achieved by using a desiccant rotor in addition to the conventional chilled water dehumidification. This helps in reducing humidity, lowering dew point and optimizing the dryness in air before it comes in contact with the product being manufactured.
