Hydrosorbent Silica Gel Item #SG900
- Our largest unit is ideal protection when winterizing boats, cars and RVs. It can improve air quality when used in enclosed spaces in the home. The XL Pack contains 900 grams of silica gel packaged in a heavy duty corrugated carton that measures 6" x 3" x 8 1/2". Protects 66 cubic feet of enclosed space.
- Be sure that the end containing the indicator card is on the bottom so that the active ingredients rest on the indicator card. Examine the indicator from time to time. When the indicator changes from blue to pink, follow the reactivation instructions below. (Reactivation instructions are also printed on each unit.)
What to do when the indicator shows that the silica gel is saturated:
Remove the bag of silica gel granules from the carton (never, ever, put the carton containing the bag of crystals in the oven!) and place the bag in a vented 240 degree F oven for at least 3 hours. Replace the bag in the unit. Please note that it may take several hours for the indicating circles to turn blue again.
After reactivation is complete and the unit is cool enough to handle, return the unit to the enclosed space you wish to protect immediately. If you leave the unit in the open it will rapidly absorb moisture from the surrounding air.
