Indicating Silica Gel

Indicating Silica gel is extremely efficient at temperatures below 77°F (25°C)

Typical Applications include: Dry food products such as jerky, medicine, vitamins, shoe boxes, electronics. Silica Gel is also widely used in compressed air systems. It is possible to prevent system failures due to the accumulation of moisture by filtering the compressed air through a packet of silica gel. Compressed air systems with moisture adsorbers are also needed to prevent the degradation signals transmitted by high-capacity radio and satellite transmitters. Indicating Silica Gel changes color when it has reached its moisture adsorption capacity.

What makes molecular sieve the best desiccant?

Molecular sieves retain their ability to adsorb water molecules over a much wider spectrum of temperatures than other desiccant materials. Molecular sieves also have a much higher equilibrium capacity for water vapor under very low humidity conditions.

Molecular sieves contain a uniform network of crystalline pores and empty adsorption cavities, which give it an internal adsorptive surface area of 700 to 800 gm2 (1/2 the total volume of the crystals). Because of its uniform structure, molecular sieves will not desorb moisture into the package as readily as silica gel or clay as temperatures rise. Being synthetic rather than naturally occurring, molecular sieve is higher in cost per unit, but due to its extremely large range of adsorptive capabilities, it is often the best value.
