Dehumidifier B-296

Functional principle of the Dehumidifier B-296

The Dehumidifier B-296 can be used for various purposes. First it can be used to pre dehumidify the drying air before Spray Drying, like this reproducible results with the BUCHI Spray Dryers can be achieved even in humid areas. Second the Dehumidifier B-296 can be used to pre chill the cooling air for Spray Chilling applications. Third the Dehumidifier will allow to Spray Dry organic solvents and water mixtures. In combination with one of the Spray Dryers and the Inert Loop B-295 it will remove the water from the drying gas before entering the Inert Loop B-295.

Do we have the possibility to spray with organic solvents?

With the Mini Spray Dryer B-290 or with the Nano Spray Dryer B-90 with the Inert Loop B-295 it is possible to spray with organic solvents without risk of explosion, because the system works under inert conditions.
