Watchdog Oil Dryers
Watchdog Oil Dryers are a passive-drying system designed for bearing housings and other applications where moisture condensation must be minimized. Relative humidity is substantially reduced in most applications. The compact design and standard thread sizes are designed to simplify installation. Standby equipment can be protected from internal moisture damage when the Watchdog Oil Dryer is installed.
Feature
Visual Indication
When maximum adsorption is reached the silica gel turns from orange to dark green, indicating replacement is needed. The silica gel used is chemically inert, non-corrosive, and does not contain cobalt chloride, a heavy metal. The color changing dye used is environmentally safe and meets all health and safety requirements.
