Non-indicating silica

 

This range of Silica is used not only in small scale, but can also be used in bulk application, e.g. as guard bed on top of the Molecular sieve bed, e.g. in Natural gas plants.

Silcas tend to crash when in contact with liquid water, hence this must be avoided.

The product ZEObeads however is specially designed for applictaions when a contact with liquid water is possible (e.g. in breake systems of trucks, busses and locomotives.
