A renewable desiccant dehumidifier operates working with silica gel beads that adsorb humidity from the air. Much like the disposable type, it's little in dimensions, capacity, and price tag. It also doesn’t require electric power to start working, rendering it perfect for wardrobes, kitchen pantries, and gun safes without energy https://dstdehumidifiers.co.uk/case-studies/desiccant-dehumidifiers-in-cold-stores/
