WebHow is silica gel regenerated ? Self-indicating silica gels when they have become saturated can be regenerated by heating at 100 - 120°C until they return to their original colours. The heating literally drives off the adsorbed moisture. Regeneration can be carried out repeatedly, although eventually the crystals will lose their colour. WebA well-designed, properly used molecular sieve adsorption device, its life should be between 24,000-40,000 hours, which is about 3-5 years.
