A refrigerated air dryer is the most commonly used. type of
compressed air dryer for most plant application for the drying
of plant air and other utility gases like hydrogen gas, nitrogen
drying etc. where a dew point (+2) Deg. C at line pressure i.e.
(-22) Deg. C at atmospheric pressure) is an acceptable norm.
In small Air capacities upto 400
NM3/hr MGS-L model is offered. It has simple and very
compact design consisting of a cylindrical heat exchanger with
Freon tubes. Air flows outside the tubes and gets cooled to 3°C
temperature. Moisture condenses out and is drained out continuously.
The out going air is at 3°C temperature with (+) 3°C Pressure
Dew Point which is equivalent to approx (-) 23°C dew point at
atmospheric pressure.
For larger air capacities, above 400 NM3/hr, we recommend MGS-H model. It is a skid mounted unit consisting of
Air-Freon chiller, Air to Air pre-Cooler and a moisture
separator. First air is precooled with outgoing chilled air to
around 25°C and then it is cooled in a Freon cooler upto {+) 3°C
temperature. This reduces refrigeration load of the Unit.
Outgoing dry air has (+) 3°C Pressure Dew Point and comes out at
around 25°C temperature. (+) 3°C Dew Point in Refrigerated Air
Dryers corresponds to around (-) 23°C Atmospheric Pressure Dew
Point. Still lower Dew Point is not possible from Refrigerated
Dryer as moisture condensed would start freezing on Freon tubes
if lower dew points are tried.
(-) 23°C is the best possible Dew Point achievable from
Refrigerated Air Dryers.
