Where and how is bulk silica gel used?

For protection against damage due to moisture and dampness, such as corrosion and mold, bulk silica gel can be used in a variety of ways during processing, storage and transport of products. It is primarily used in industrial drying systems, laboratory supplies, compressed air drying and pressure equalization containers. It is excellently suited for static drying of air and gases. Silica gel consists of hard, glass-like beads of silicon dioxide. Their large internal surface area can absorb a large amount of water. The silica gel adsorbs water molecules. The water does not change its structure, remains in its form and can be released again during regeneration.
Handling is simple and flexible. The desired amount of bulk silica gel is placed in the enclosed area to be dried. It can be distributed either loose or in additional containers. Silica gel is regenerable due to its properties, which makes its use sustainable. Regeneration is carried out by heating in an oven at 100-150 °C.

Special feature Silica Gel Orange

From a water content of approx. 6%, the orange beads turn green. With further saturation of the desiccant, the green coloring becomes more intense until it is completely saturated. A green-blue coloring signals complete saturation. Weighing to check the degree of saturation is therefore unnecessary.
