Replacement Desiccant. As the desiccant absorbs moisture, a dramatic and high visible color change from dark blue to light pink is evident. The color change works it's way through the desiccant as the absorptive qualities of the desiccant are diminished. Once the color change is visible through the exclusive sight dome, the full desiccant bed has reached its maximum drying capacity and should be either changed or regenerated.
