Desiccant bags - red silica gel Red silica gel desiccant bags – Efficient protection with visual moisture control! Red silica gel desiccant bags are filled with high-performance silica gel that contains a special color indicator. This indicator enables precise visual monitoring of the saturation level: as the gel absorbs moisture, its color changes from ruby red to yellow, making it easy to assess the loading status at a glance. The adsorption capacity of Red silica gel desiccant bags can reach up to 30 % of their weight at 80 % relative humidity and 25 °C, providing reliable protection against moisture.
