Refrigerated Type Dryer
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 +2-30C approx i.e. the dew point of dried fluid at operating pressure 7 kgf/Cm2g is (+) 20C and its corresponding atmospheric dew point would be (-) 220C (approx). These dryers are suitable for the applications where the maximum dew point of (-) 20 to (-) 220C (Atm.) is normally acceptable.
Compressed Air Dryers
Moisture Use Air / Gas Dryer
Water or Moisture in the compressed air system causes air leakages, damages tools systems and ultimately increases cost.
Problems due to unwanted moisture in the compressed air system
This results in loss of efficiency & material and increases downtime. Moisture is usually the single major cause of unnecessary costs to compressed air system. The cost of drying air is much lower than the damage. Thus clean, dry compressed air produced using air Dryer is essential for effective pneumatic system.
