Contact SupplierHOC Air Dryer is a fully automatic mass quantity instrument designed for process air in chemical industries & other engineering applications where mass volume air may be required. HOC Air Dryer ensures continuous duty with long efficient service life. The maintenance of HOC Air Dryer is easy to as there are no Blower no Heaters, and no moving parts. HOC Air Dryer has low-pressure drop across the dryer less than 0.3 kg/cm2.
Working
HOC Air Dryer has NIL operating cost in this design hot air coming out from Air compressor discharge is used for regeneration of desiccant and so no external electric regeneration heating is required. This design easily produces dry air of (-) 40o C Dew Point.
Technical Specifications
Operating principle
The Heat of compression dryers (HOC) are the latest generation chemical dryers based on adsorption principle. It does not have complex valuing & is eliminated with purge loss drawback as in heatless type dryer.
The hot air from the compressor at 120o C and higher temperature is used directly for regeneration of the desiccant. After regeneration, this air is cooled down to 40oC and then it is dried in second tower. Thus, the use of heaters is eliminated. For e.g. in the 6+6 Hrs. Cycle the hot air is fed for regeneration for 4 Hrs. and for balance 2 Hr. a changeover takes place where the air is first cooled in cooler, then dried and before going to the outlet, cools the regenerated desiccant bed, thus bringing it down to ambient temperature. This cycle is reversed for the next 4hrs, where the absorber drying the air in the previous cycle goes for regeneration and vice versa.
