Silica Gel

A pile of silica gel beads

Product Overview

Sorbead® Air adsorbents (formerly known as KC-Trockenperlen) are comprised of alumino-silicate gel beads used in the drying of compressed air, technical gases and in power transformer breathers.

Three grades are available: Sorbead® Air R, Sorbead® Air WS and Sorbead® Orange CHAMELEON®. WS is a water stable grade often used as a guard layer in combination with other desiccants. CHAMELEON® is an indicating silica gel used for moisture sensitive applications, such as transformer air breathers.
