Calcium chloride utilizes premium quality raw material that can absorb moisture from the air rapidly and can be used as a multi-purpose desiccant in the industrial field, such as for drying nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, and other similar compounds. It can be used as a dehydrating agent in the production of alcohols, esters, ethers, and acrylic resins.

Calcium montmorillonite is a natural mineral with interlayer cations of calcium ions. Its appearance is mainly a 1-4mm white or light-yellow particles, and it also has gray, purple, and other colors due to different iron content. Montmorillonite adopts physical adsorption and can absorb more than 17% of its weight of water vapor at 25°C and RH40%. Montmorillonite particles can be reused after being reactivated. It is a natural, environmentally friendly, economical, and affordable adsorbent material.

High-quality silica gel uses physical adsorption. It has a strong moisture absorption capacity and both chemical and physical stability. It is also non-corrosive, non-toxic, and harmless. The silica gel can be reused after being reactivated. Normally, the silica gel particle size is 2-4mm. And silica gel has transparent white gel (white gel type A, white gel type B) and indicating silica gel. Indicating silica gel has an indicating function. The state of moisture absorption can be judged by the change of colors. At 25°C, Rh20%, the silica gel will start to change color after absorbing moisture and completely changes color after absorbing moisture under the condition of RH50%-60%. Based on different types of indicating silica gel, the color can be changed from blue to red, orange to light green, orange to dark green, or orange to white. The reusable silica gel beads desiccant dehumidifier can be reactivated by placing into the oven for 0.5h-3 hours at 200°F-250°F (do not over 250°F). Depending on silica gel beads condition, they may take shorter than the recommended time. Please check the silica gel beads color.
