A dryer is an typre of equipment, that
consumes compressed air.
Reducing the amount of compressed air, used to adsorbent regeneration, is a challenge that must be addressed to reduce
the cost of air production.

The design of the adsorption dryer should ensure efficient
heating of the adsorbent and its subsequent cooling.
In the construction of the dryers uses:

directly.
The great value of the dielectric constant is explained by the peculiarities of the H2O molecule. The large value of the static permittivity of water (ε = 81) is due to the fact that water is a strongly polar liquid and therefore has a soft orientation degree of freedom (ie rotation
of molecular dipoles).
