General information

Desiccants

Desiccants can absorb water and bind it chemically (reversibly or irreversibly) or physically. The main desiccants can be subdivided into four categories:

• non-renewable chemical desiccants
• renewable chemical desiccants
• silica gels
• molecular sieves

Silica Gels

Silica gels protect moisture sensitive goods or chemicals during storage and transport. They are suitable for drying virtually all gases and solids.

Silica gels have a broad spectrum of application in the laboratory and in technical and industrial sectors:
• Possible applications in the laboratory are in desiccators, drying towers and in absorption tubes
• In the industrial sector they are mainly used in drying plants and with various types of packaging
• Are not suitable for drying liquids and alkaline substances


In order to achieve low residual water content over the silica gel, the capacity can only be utilised partially. The less silica gel is loaded with water the more intensively it dries. For example, to achieve a residual water content of 1 mg/l the loading must not be higher than 5,2 g water / 100 g silica gel.


Regeneration:

Is not possible for the desiccant bags, as the long fiber paper is not temperature-stable.
