Heatless Air Dryers Operating principleIn Heatless Dryers, two vessels 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 downward through the desiccant bed in the 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 air flow. At preset interval, the vessels changeover automatically, and Dry air is available continuously, without any surges.Simple Design / Easy operationThis is the simplest type of Air Dryer with Activated Alumina / Molecular sieves drying agent. This design is virtually maintenance free, fully automatic, and requires no attention for years. Heatless type dryers do not require any heating for re-generation and therefore are very simple in design and maintenance free.Low Investment / Low operating cost Due to its inherent simple design, investment in this type of dryer is the cheapest and the payback on this investment is very quick. Low temperature operation reduces corrosion in towers and desiccant lasts longer. Power requirement is single phase 220 /110 volts,50 Hz , 60 watts only for solenoid valves operation.

A heatless air dryer consist of two towers, which, alternately cycle on drying and regeneration. Each tower is filled with a bed of adsorbent desiccant. When one tower is on drying cycle, the desiccant adsorbs moisture from the incoming wet air stream and the other tower is on a regenerating cycle, which, a small portion of the super dried air passing through the desiccant to pick up and remove the adsorbed moisture, which is then vented to atmosphere. The towers are alternated in such a manner so that dry desiccant is always in contact with wet compressed air, resulting in a continuous supply of dry air downstream. The process is automatically reversed from one tower to another by a microprocessor based sequenced timer. Dryer must be protected against water and oil suspended in the form of drops or finely dispersed mist. If the risk for such condition exists, a high efficiency pre-filter must be installed before the dryer. In regular course a ceramic candle pre-filter is installed prior to the dryer to take care of incoming dust, dirt and foreign particles. By default a ceramic candle after-filter is installed after the dryer to take care of desiccant dust carry forward in the dry air. The “pearl” make heatless dryer is capable of providing a -400c or lower atmospheric dew point and features a non-lubricated 3-way pneumatic switching valve. The operation is fully automatic and continuous without attention. features : pressure equalization : ensures dry air supply is continuous and at constant pressure. electronic timer : highly precise and fail-safe with excellent repeatability low dew point : constant atmospheric dew point of - 40 c or below. instant dry air availability : easy to install & operate, requiring very few, low-cost spares. low power consumption : approximately 50 watts only. equipped with silencers : low noise level.

Atmospheric Air is sucked by air Compressor which basically contains water vapour & dust. Besides, in lubricated type Air Compressors, oil is present in the air compression chamber, traces of which are present, in compressed air in Liquid / Vapour form, which condenses into a heavy gummy oil varnish. Condensed moisture together with dust and oil in compressed air leads to emulsion formation causing following troubles: Formation of rust & scale, clogging orificies, resulting in malfunctioning of tools, controls & instruments.Freezing in air lines causes malfunctions & damages to process Equipments. Increased resistance to flow. By corrosion of air or gas the instruments can give false reading disrupting product quality. Rust & scale contaminates products when compressed air is used in mixing and processing. Bubbling effect in spray painted / Powder coated items. Sluggish operation of pneumatic equipments. If the temperature of the compressed air is more then 40o C then it is necessaroy to provide AFTER COOLER which should ensure the outlet temperature of 400C. During this cooling process, some moisture condenses which is removed our from prefilter. If the Air compressor is non-lubricated type then there is no need of Activated Carbon Filter, but if the Air Compressor is lubricated type them Activated Carbon Filter before Compressed Air Dryer / heatless air dryer is must. The characteristic of Activated Carbon is to remove the oil vapour totally from the compressed air. This ensure the full life of the desiccant in Compressed Air Dryer / Heatless air dryer . The HEATLESS type Air Dryer is the simplest & Economical Air Dryer with Activated Alumina Molecular Sieves as the desiccant. The twin Absorbers of Air Dryer is filled with these desiccant and is assembled with 3-way, 2-way, control valves and interconnected pipings. The Air Dryer / instrument air dryer follows the Drying sequence of 10 minutes. Here one absorber of dessicant air dryer is under drying cycle for 5 minutes and simultaneously the other absorber of air dryer under goes for regeneration and equalization process for (4 + 1) 5 minutes respectively. The changeover of the absorber takes place with the help of sequence timer. The moistured air and regenerative air is drained out through the individual silencer of the absorbers provided at the bottom hence super Dry Air comes from the top of the Absorber & is taken to your process for your applications. During this cooling process, some moisture condenses which is removed from prefilter. Salient Features : Super Dry Air by low investment. 100% Oil & Moisture free air with Dew Point of (-) 40oC (

C. or (-) 70 deg C as required Ideal purging as per desiccant manufacturers instruction for regeneration Lesser pressure drop in total unit Modified purge silencer causing less noise Designed for Indian atmospheric condition Easy for installation and commissioning Sequence of Drying Operation : It is as per following three stagesPrefiltration : The dust particles, condensed oil and moisture in liquid droplets and aerosol from is per-filtered by set of pre-fine filter combination, The Compressed air with only vapourised from of moisture is permitted to enter the desiccant bed tower.Drying : The Saturated Compressed air is dried in desiccant bed tower.Postfiltration : The dry compressed air is refiltered in after filter for removal of residual fine particles if any.Operation : The complete ADU operates in following three modes.Drying Mode : The wet saturated compressed air coming from set of pre filters is led through one of the inlet valve (Operated by electronic timer) to the desiccant bed tower. The highly hygroscopic desiccant bed with sufficient air resident time due to proper velocity results in absorbing the moisture vapour and dries the air to desired level of dew point.Regeneration Mode : The small amount of dried air at almost atmospheric pressure is led through purge line to the saturated desiccant bed tower. The absorbed moisture in desiccant bed at earlier drying mode is desorbed in purged dry air and regeneration takes place.Pressurisation Mode : To avoid the pressure fluctuations at outlet of dryer, the regeneration mode tower is put in for pressurisation before it switches to drying mode. The entire operation is electronic timer controlled and automatic at various modes shown above for proper sequence and timing. The total cycle time is 10 minutes or 4 minutes as per timer selection for required dew point.

Heatless type Dryer takes advantage of the natural phenomenon of desiccant to establish equilibrium with their surrondings. In this type, wet Air (fluid) is cycled automatically between two desiccant towers, one adsorbing the moisture from the wet fluid, while the other being regenerated. The wet fluid enters one tower, passes through the desiccant bed where the saturated moisture is absorbed. A small portion of the dried air at ambient temperature and pressure is passed through the desiccant bed in the second tower for regeneration. At present interval, the towers changeover automatically and the cycle continues giving out a regular supply of super dry air having dew points up to (-) 70oC(Atm.)Other Type of Absorption Dryers available are: Embedded Internal Heat Adsorption Dryer. Blower Heat Regenerated No Loss Adsorption Dryer. Split Flow No Loss Adsorption Type Dryer. Heat of Compression No Loss Absorption Dryer.
