Dehydrator

A dehydrator dries the air compressed by a compressor . The air is usually passed through one or more desiccant cartridges filled with granules of silica gel . This silica gel is very hygroscopic and absorbs the humidity in its crystal lattice. It changes its color, which can therefore also be used as an indicator.

application

The dielectric strength and transmission attenuation of a waveguide is greatly impaired by air humidity inside. Therefore, the entire waveguide system is filled with compressed air, which has been dried in a dehydrator. If there is a leak somewhere in the system, compressed air will constantly escape there and thus prevent moisture from penetrating. In addition, the reduction in air pressure can be used as a measure of the tightness of the system in order to trigger protective circuits.
