When the air is compressed, the
volume decreases proportionally but all the exhausted water vapor
still remains in air. When the temperature decreases and reaches
a value at which the air becomes saturated, the humidity kept before
by the air begins to condensate, this is called DewPoint.
With an appropriate aftercooler
unit, which reduces the temperature of the air produced by the compressor
considerably, approx. 60°l-70% of the water is condensed. It
is possible to eliminate the remaining 40%-30°l with the installation
of a FRIULAIR dryer.
Damage caused by condensate
Condensate corrodes piping, solenoid valve, pneumatic tooling and
the user is then obliged to stand expensive repair inteventions
especially the expensi~e "down times" which means cannot
be controlled very easily.
In the case where the compressed
air is used as "process air" such as for painting equipment,
chemical industry, food-processing industry, glass factories, flour
and raw materials conveying and handling plants, the installations
of a FRIULAIR dryer is essential to eliminate the condensate polluting
the production cycle.
