Özen Heatless Desiccant Air Dryers provide constant -40 °C pressure dewpoint.These dryers are designed to supply clean and very dry compressed air for critical applications.Pre-filters and after filters are supplied together with Özen Heatless Desiccant Air Dryers to keep the air stream clean and maintain the integrity of the desiccant medium. The so special valves and desiccant provide lowest pressure drop.
Thet win towers at OCD Desiccant dryers with high-strength structure and absorbent desiccant provides continuous cooling.
While compressed air drying by leaving moisture at first desiccant bed, the second desiccant bed simultaneously regenerated with service air to be ready for drying process.
Regeneration of desiccant at OCD Desiccant Dryers accomplished without use of heat. The wet desiccant bed dried by diverting a small amount of the dry air from the out which is close to atmospheric pressure. The purge flow rate is adjustable to match required dew-point as per outside conditions. The super dry air flows in a counter direction through the wet bed, sweeps all water vapour which absorbed by the desiccant.
OCD series Desiccant Dryers ensures pressure equalization in the twin towers prior to switching by this way prevent line surge and minimizes desiccant attrition. After regeneration the towers reduce pressure gradually for pressure equalization before switch off. Purge flow and de-pressurization move in downward direction, counter flow to drying flow.
The reliable PLC control panel with touch screen at OCD Desiccant Dryers, operates dryer perfectly during whole service life. Control panel shows on real time the valves which are operating and cycles. Displaying dew point is possible as optional. Multi language option provides so easy use.
Ozen use a mixture of adsorption media for heatless dryer range to achieve constant dew point. Activated alumina, Molecular Sieve and Silica Gel are used in varying ratios depending as per application.
The pre filters and after filters which supply together with OCD Series Desiccant Dryers, keep the air stream clean and maintain integrity of the desiccant medium. A very reliable electronic controller controls well the dryer during operation life and follow all maintenance times. Thanks to using so special valves and chemicals provide so low pressure drop against all competitors. Beside of energy save help the environment for keeping “Green”.
