Silica gel dehumidifiers from Hydrosorbent® prevent rust and mold, rot, corrosion and musty odors from developing in your valuable equipment such as electronics, cameras, computers or optical instruments.

Built-in indicator.

A built-in indicator indicates when the Silica Gel needs to be dried again. With sufficient moisture in the Silica Gel, the color changes from blue to pink. In that case you can easily dry the unit in an oven at 149 C° (minimum 3 hours or until the Silica Gel turns dark blue again). After that the unit can be used again.

Available at Vonk B.V.

The different applications of Hydrosorbent® are available on our website.
