Desiccant Required (in units)
|
|
The following desiccant requirement chart for unit size bags shows the amount
of Desi-Pak (clay desiccant) or Sorb-It (silica gel desiccant) that you need for any given product
or package.
To use, simply:
1) Determine how your item is packaged. Most sealed packages fall
within two categories. A) Plastic bags or other flexible barrier
materials. B) RIgid containers made of plastic or metal and drums
made of fibers.
2) Calculate the volume of your package in either square feet/inches, gallons
or cubic feet/inches.
3) Match the calculated volume of your package with the appropriate column
below.
4) The far right column indicates the amount of desiccant your package
requires.
