Orange Indicating Silica Gel, also known as Yellow Indicating Silica Gel, consists of purified silicon dioxide processed into beads. Dry beads exhibit a yellow/orange hue, transitioning to green when saturated with moisture, indicating the need for replacement or regeneration. Conforming to EU regulations banning cobalt dichloride, a toxin, it’s widely used in industries like compressed air dryers, gas drying, and transformer breathers. Available in 2mm-5mm bead sizes, it boasts high adsorption capacity and operates effectively up to 150°F (65°C), though optimal at room temperature. Environmentally friendly and non-toxic, it’s unsuitable for direct contact with consumables like food and pharmaceuticals.
