Silica Gel Breather of Transformer | Electrical4U· The silica gel is a very good absorber of moisture. Freshly regenerated gel is very efficient, it may dry down air to a dew point of below -40 o C. A well maintained silica gel breather will generally operate with a dew point of -35 o C as long as a large enough quantity of gel has been used. The picture shows a silica gel breather of transformer.[email protected]
