| The problem: |
Compressed Air produced by any compressor always contains water vapor. This vapor can cause a variety of problems which can seriously affect the efficiency of the system causing:
- Corrosion of components
- Down time necessary to repair damaged tooling/machinery
- High maintenance cost
- Ruined paint jobs

| Solution: |
For these reasons, a drying system must be installed after the pumping section of any compressed air system. Within the refrigerated air dryer, the temperature of the air is lower causing the water to condense out of the air. The air is then passed through a cyclone type separator which separates the air and water. The water is then ejected as waste and the dry air may be used to perform it's desired function.
Wet Compressed air undermines efficiency of smallest to the largest pneumatic system. Therefore, moisture removal in compressed air system installation is a must. The drying of Compressed air by DUEX Refrigerated Air Dryer is the most economical and reliable process of compressed air treatment. The incoming saturated, moist air is pre-cooled in the Air - to - Air Heat Exchanger (6) by the outgoing dry chilled air. In the process, a greater part of Water Vapor gets condensed into liquid moisture. Further moisture separation takes place in the Freon -to- Air Heat Exchanger (7) where air is chilled to a temperature of +2 Deg. C. and moisture condenses. This temperature is termed as pressure 'Dew Point'. The Moisture Separator (8) removes the
condensate by an Automatic Condensate Trap (12) i e. auto drain. |

| The compressed dry air is reheated in Air -to- Air Heat Exchanger and fed to the point of application. As long as compressed air temperature remains above the +2 Deg. C., no further condensation will occur. The Dew Point of +2 Deg. C. is sufficient enough for the smooth and trouble free operation of most of industrial pneumatic / process applications. The refrigeration circuit is the conventional circuit comprising refrigerant Compressor (1), air or water cooled Condenser (2), Expansion Valve (5) etc. using Freon R-22 as refrigerant gas. Use of R-22 as a refrigerant is permissible up to the year 2030 AD. as per Montreal Protocol. System with Eco-friendly Refrigerant like R-134 A, R-404 A, R-407C are also offered. Air Cooled (AC) models are available up to 2750 CFM and higher models are available with water cooled condenser |
