Heatless Dryer simplest type of air dryer with Activated Alumina/Molecular Sieves drying agent. Heatless Dryer is virtually maintenance free, fully automatic, and requires no attention for year. Heatless Dryer does not require any heating for re-generation and therefore are very simple in design and maintenance free.
Operating PrincipalIn Heatless Dryers, two vessel filled with desiccant are provided which cycle automatically, producing dry air continuously. In these units, wet air enters the bottom of one Vessel and passes upwards through the desiccant bed where the moisture is adsorbed. The dry air comes out from the top. A small portion of dry air is passed downwards through the desiccant bed in second vessel, which is under re-generation. Moisture laden purge air is then vented out to atmosphere. The purge loss is around 7.5% of the total airflow. At preset interval, the vessel changeover automatically, and Dry air is available continuously, without any surge.
Low Operating CostDue to its inherent simple design, investment in this type of dryer is the cheapest and the payback on this investment is very quickly. Low Temperature operation reduces corrosion in tower and desiccant lasts longer. Power requirement is 60 watt only for Solenoids Valves Operation
Capacity
HOC 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.
WorkingHOC 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 principleThe 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.
Heat Reactivated Air Dryer is used when one needs compressed air of very low dew point of (-) 60o C or 80oC. In Heat Reactivated Air Dryer, 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 points.
Operating PrincipleThe 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 regenerates 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 degree c. At this temperature, regeneration is complete (due to dry air purge). Dew point achieved is around 40 degree c. If still lower dew point is required, air-purging rate is slightly increased to 5% for 60 degree C and to 7.5% for 80 degree C DEW point requirements.
FiltersA pre-filter with automatics drain valve is provided to remove any physical moisture from Compressed air before entering air Dryer. A Micron filter is also provided in dryer outlet to arrest any desiccant dust particles, up to 1 micron size. Thus you get absolutely “Clean & dry compressed air.

CO2 Gas Dryer are used to removing of Moisture in Co2 gas mostly used in food and Braveries Industry. After Installed Co2 dryer dew point of (-) 60oC . In this design, the desiccant is regenerated at higher temperature, along with small quantity of dry Co2 Purge. Due to purging with dry Co2 and thermal regeneration, residual moisture loading on desiccant becomes low and this gives very low dew points.

Operating Principle :The Co2 drying unit has 2 vessels filled with Molecular sieves desiccant. One vessel remains in drying cycle for 4 hours, while other vessel is simultaneously regenerates at atmospheric pressure. Around 2 to 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 150 degree c. At this temperature regeneration is complete (due to dry Co2 purge). Dew point achieved is around (-60 C) If still lower dew point is required, Co2 purging rate is slightly increased to 5% for (-60 C) and to 7.5% for (-80 C) Dew point requirements.
Filters : A pre-filter provided to remove any physical moisture from Co2 Plant / Co2 tanker before entering Co2 Dryer. A Micron filter is also provided in dryer outlet to arrest any desiccant dust particles, up to 1 micron size. Thus you get absolutely “Clean & dry compressed air.
