A refrigerated air dryer is the most commonly used. type of compressed air dryer for most plant applications for the drying of plant air and other utility gases like hydrogen gas, nitrogen drying etc. where a dew point of (+2) Deg. C. at line pressure i.e. (-22 )Deg. C. at atmospheric pressure) is an acceptable norm.
As much as 2300 gallons of moisture can be removed from a100 cfm pneumatic system operating at 100 psi in 12 months of 3 shift operation, moisture which without a refrigerant air dryer, would have passed through the delicate pneumatic equipments & instruments

FEATURES OF REFRIGERATED AIR DRYER
A full range of aircooled as well as water cooled refrigerant air dryers are available for moisture removal & to provide dry clean air to any size and type of compressed air & pneumatic systems
ENERGY EFFICIENT HEAT EXCHANGER
Power consumption reduced by upto 10% over conventional refrigerated dryer system.
ADVANCED DESIGN
Moisture Dirt and oil contamination is removed by either impaction or integral filtration-ensures maximum protection for pneumatic compressed air equipment at all times
CONTAMINANT REMOVAL DOWN TO 1 MICRON
Minimal additional filtration is required after the refrigerated dryer for most applications.
TRIED AND TESTED CONTROL SYSTEM
Ensures maximum reliability of the refrigerated air dryer at all times.
LOW NOISE LEVELS- 60 DB (A)
Suitable for location in indoor working environment
Operation
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 Mellcon Refrigerated Air Dryer is the most economical and reliable process of compressed air treatment. The incoming saturated, moist air is precooled in the Air - to - Air Heat Exchanger (6) by the outgoing dry chilled air. In the process, a greater part of Water Vapour 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 freeoperation 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 Ecofriendly Refrigerant like R-134 A, R-404 A, R-407C are also offered. Air Cooled (AC) models are available up to 2300 SCFM and higher models are available with water cooled condenser. |
