Cooling is the simplest and most positive way of removing moisture from compressed Air. A Refrigerated Dryer has closed-loop Freon circuit, which cools compressed air to a controlled temperature and so condensed moisture is separated out. To prevent freezing of condensed moisture in the heat exchanger, Air/Gas, can be cooled to a minimum temperature of +2-3°C  approx i.e. the dew point of dried fluid at operating pressure 7 kgf/Cm2g is (+) 2°C  and its corresponding atmospheric dew point would be (-) 22°C  (approx). These dryers are suitable for the applications where the maximum dew point of (-) 20 to (-) 22°C  (Atm.) is normally acceptable.

Water or Moisture in the compressed air system causes air leakages, damages tools systems and ultimately increases cost.
