Silica Gel & Breather

Silica gel and breather assemblies are moisture control devices used in transformers and electrical equipment with oil-filled conservator tanks. The breather contains silica gel desiccant that absorbs moisture from incoming air as the equipment breathes during temperature-related expansion and contraction of oil. This prevents moisture contamination of insulating oil, preserving dielectric strength and extending equipment life. Typical technical characteristics include color-indicating silica gel, transparent breather housings for visual inspection, moisture absorption capability, oil seals, and suitability for outdoor industrial installations.
