White silica gel in amorphous crystal form, in granule format, is a desiccant material without color indicators. It is available in two particle sizes: standard (2 to 5 mm diameter) and fine (0.5 to 2 mm diameter). Visually similar to coarse kitchen salt, it does not change color as it becomes saturated. Therefore, its moisture level must be monitored through periodic weighing or indirect control methods. This product is particularly suitable for use in industrial gas and air treatment systems, in fixed or dynamic bed filters, and in dehumidification setups where visual monitoring of the desiccant's condition is not required.
