PPE supplies both types 13X and 4A molecular sieve desiccant
in two bead sizes. Due to the various designs of desiccant plastic
material dryers, you must replace your bed material with the
same type and size that was supplied with your dryer.
Molecular sieve desiccant type 13X has a 12% higher moisture
absorption capacity and a larger pore size than type 4A. The
larger pores allow it to absorb moisture faster and also absorb
larger molecules of moisture as well. Depending on the quantity
and type of molecules present, these could react on the surface
of the 13X during regeneration and not come off, thus reducing
its capacity to function over time. Type 13X is more subject to
contamination which in time renders it ineffective.
Because of type 4A’s smaller pore size, it is less subject to 4A 1/8” 4A 1/16” 13X 1/8” 13X 1/16”
contamination. However, because of its lower absorbtion capacity
and smaller pore openings, the rate at which it absorbs moisture ALWAYS KEEP YOUR AIR INLET FILTERS CLEAN!
will be lower than with type 13X.
Another factor to consider is the bead size. Small beads (8x12 mesh) have a faster rate of water absorption, but they are
more dense and cause a higher pressure drop than the larger (4x8 mesh) beads. Always specify the correct type and size
molecular sieve desiccant. If you don’t know which type of sieve your dryer was designed to use, contact your dryer manufacturer
for their recommendation and then call PPE to place your order.
