Process: Wet incoming compressed air after passing through pre filter passes through the slide piston valve assembly and is directed towards absorber chamber i where the compressed air passes upward through the desiccant ( activated alumina / molecular sieves ). Compressed air drying takes place by adsorption. Dry compressed air from absorber chamber i then passes through the check valve assembly and then through the after- filter to the application or work area. while compressed air is being drying in chamber the desiccant in chamber where the desiccant has been wetted in the previous cycle is being simultaneously regenerated. The chamber is depressurized to atmosphere through the purge valve in the downward direction. A portion of the dry compressed air passes through the needle valve / orifice plate through the desiccant and flushes out the desorbed moisture. when the regeneration is complete, the purge valve is closed and the tower is slowly repressurise to line pressure for a smooth changeover. A drying period of 5 minutes provides an efficient dew point of -40o C or better (at atmospheric pressure ). In regeneration process approximately 30 seconds are required for repressurization.

Heat Reactivated Type Air Dryers are used when one needs compressed air of very low Dew point of (-) 60°C or (-) 80°C. In this design, the desiccant is regenerated at higher temperature, along with small quantity of Dry air purge. Due to purging with Dry air and thermal regeneration, residual moisture loading on desiccant becomes low and this gives very low Dew point. The Drying unit has 2-vessels filled with Activated Alumina or Molecular sieves desiccant. One vessel remains in drying cycle for 4 hours, while other vessel is simultaneously regenerated at atmospheric pressure. Around 3% flow of dryer capacity is used as purge for regeneration. Electrical heaters are provided in a central finned Stainless steel pipe in both drying vessels. Heating cycle is for 2 hours and in this time hot purge air increases desiccant temperature to around 100°C. At this temperature regeneration is complete (due to dry air purge). Dew point achieved is around (-) 40°C. If still lower Dew point is required, air purging rate is slightly increased to 5% for (-) 60°C and to 7.5% for (-) 80°C Dew point. SAM Gas Filters A Pre-filter with automatic drain valve is provided to remove any physical moisture from compressed air before entering Air dryer. A micronic filter is also provided in the Dryer outlet to arrest any desiccant dust particles, up to 1 micron size.

In Regenerative desiccant air dryers, directly from Air compressor discharge is taken to Air dryer inlet through insulated pipelines, at 120o C (minimum) temperature. This hot air is passed through one drying vessel where saturated desiccant is regenerated by this hot air. After picking up moisture from desiccant bed, the air is cooled in an intermediate cooler. Here moisture is condensed and removed by auto drain valve. Cooled to 40o C, this air passes through the second drying vessel where balance moisture gets adsorbed and Dry air comes out. Cycle time is 4 hours regeneration & 4 hours drying. After 4 hours the changeover of vessels takes place automatically. In regeneration cycle heating of the bed is only 2 hours, and thereafter the bed is cooled by Dry air. After bed cooling, Dry air is again cooled to 40o C in another cooler, and delivered out of unit as Dry air at 40o C temp. The Dryer is fully automatic with pneumatically actuated Ball/ plug valves. A sequence timer controls operation of these valves. Desiccant used is Activated Alumina and it dries the air up to (-) 40o C Dew point.
Regenerative desiccant air dryers are specialised filter systems created with the goal of removing the water that is present in compressed air. When air is compressed, its temperature is increased and atmospheric pollutants, primarily water vapour, are concentrated. As a result, the compressed air is typically hot and humid, with a 100% relative humidity. Water vapour condenses into the tank(s), pipes, hoses, and equipment that are downstream from the compressor as the compressed air cools. To avoid condensation and keep moisture from interfering with delicate industrial processes, water vapour is removed from compressed air.
