Dryers & Filters
Refrigerant drying: Refrigerant drying cools the
compressed air, whereby a large amount of the water
condenses and can be separated. The compressed air is then
heated so that condensation does not form on the outside of
the pipe work system.
The compressed air cooling takes place, via a closed
coolant system, where a refrigerant cooling agent is
employed. CompAir uses environmentally friendly gasses for
this. By cooling the compressed incoming air with the cooled
outgoing air in the heat exchanger, the energy of the
refrigerant dryer is reduced.

Desiccant
Drying: Desiccant drying works on the principle of
absorption of water vapor through a bed of desiccant
material, in a pair of chambers. Two types are used,
heatless regenerative and heat regenerative. The heatless
type uses a percentage of the dried air (purge), for
re-generation of the desiccant material, while the heat
regenerative type uses an electric heat disk, which reduces
the amount of purge air needed for regeneration.

Filters
& Water Separators: Water Separators have been designed
for the efficient removal of bulk liquid contamination from
compressed air. Filters are used both prior to, and after
compression. Filtering the intake air reduces the intake
wear on the compressor by removing larger particles. During
the compression air can be contaminated with oil (in oil
lubricated machines) which is removed by filters. The filter
efficiency is dependant on compressor type, age, design and
condition. Filters are often setup in multistage. Fiber
filters can only trap oil as droplets, while more efficient
active carbon can trap oil as a vapor. We can help you
select the right filters for your needs.

Aftercoolers: Aftercoolers are a good first step
in removing moisture and air contaminates. They lower the
temperature to safe, usable levels, thus reducing the air's
ability to hold water vapor, removing 70%. However the air
is still saturated. A further drop in temperature will cause
additional condensation to occur in downstream airlines.
