Diffusion dryers
These devices allow a reproducible reduction of air humidity in flowing gases or drying of aerosol particles. Both models are suitable for sample volume flows in the range 0.3 … 5 l/min.
Features
- Aerosol drying with Silica Gel Orange*, color change from orange to white
- Inlet and outlet with quick coupling (Festo), 8 mm for easy integration in experimental setups
- Operation in any orientation
- Two sizes, small and large version to fit needs
* The term "Silica Gel Orange" is a product name of the company Roth
