Pelican 1500-500-000 Desiccant Moisture Absorber

The Pelican 1500-500-000 Desiccant Moisture Absorber addresses the need to maintain low-humidity internal environments inside Pelican protective cases during storage and transport of moisture-sensitive equipment. It is a passive desiccant unit — no power, electronics, or external connections required — intended to adsorb ambient moisture that enters the case through seal imperfections, pressure equalization valve cycling, or case opening events. The product is rated compatible with all Pelican cases, making it a single-SKU solution for facilities that operate a mixed fleet of Pelican case sizes.

The unit is constructed from a silica gel blend in a solid gray brick form factor, which eliminates the granule spillage risk associated with loose-fill or bagged desiccant formats. It is rechargeable via oven heating, though Pelican does not publish a specific regeneration temperature, duration, or maximum cycle count — maintenance intervals must be established by the end user. No humidity indicator is integrated into the unit; facilities requiring quantified internal RH monitoring will need to supplement with a separate indicator card or datalogger. Certification documentation (ISO, NIST, UL) is not referenced in Pelican's standard product materials for this SKU, and procurement teams with formal humidity-control compliance requirements should engage Pelican directly to confirm available documentation before specifying this unit.
