Color Changing Silica Gel
Recyclable indicator desiccant for industrial drying
Moisture-indicating silica gel for industrial air dryers and transformer breathing systems.
Product Overview
Color changing silica gel combines the drying power of silica gel with a built-in moisture indicator, giving engineers an immediate visual signal of when desiccant beds are saturated and need regeneration. It is the standard charge for transformer breathers, switchgear and instrument air systems.
Supplied in bulk or pre-filled breather charges, our color changing grade is thermally regenerable at 120-150°C and returns to its original color for repeated service cycles.
