Split Flow Air Dryers

We are well qualified manufacturer, supplier and exporter of Split Flow Air Dryers in Ahmedabad, Gujarat, India. The split flow dryers are used in order to avoid the purge loss as in the case of other dryers. The inlet air is split in a suitable ratio and the split air is used for regeneration. After regeneration the split air combines at a stage before adsorption so that there is no purge loss. The inlet air is split into two in a suitable ratio. One portion of that air is passed through a heater and then through the tower to be regenerated. The hot air carries the moisture adsorbed by the desiccant during drying. It then passes through an after cooler and a oisture separator by means of a 4/2 way valve. This air is then mixed with the inlet air at a stage and is passed through the tower in which the drying process is carried out. The dry air is finally let out after adosrption. The adsorption of moisture by activated alumina will not be effective at elevated temperatures. So the heated bed should be cooled before the drying starts in that particular tower. But if heated bed is cooled using inlet wet air, Dew point spike will occur. So heated bed should be cooled using Dry Air. For this purpose, at cooling cycle first 100% inlet air is dried through another tower. After that heated bed is cooled effectively using 100% ongoing dry air. It then passes through the another after cooler before it is let out.
