Dehumidifier B-296
 | Versatile instrument for spray chilling, inlet air conditioning or working in the closed mode with water/solvent mixtures |
Working under inert conditions for aqueous solutions
If oxgen sensitive substances are dryed, the operation is performed under inert conditions, which means under nitrogen instead of air. The decrease the nitrogen consumption, the drying gas is recycled using the Dehumidifier B-296 as cold trap. Due to the cooling temperature of +2°C, there is no danger of freezing.
If mixtures of organic solvents and water (less than 40% solvent) are used, the Dehumidifier B-296 is a suitable alternative compared to the Inert Loop B-295 to condense the solvents and to get inert conditions.
An additional external heat exchanger increases the condensation efficiency and leads to a effective spray drying process.
