Twin Tower Heatless Air Dryer

Although operating costs run higher than the heated desiccant dryers the hl series requires the lowest capital investment.

Twin tower heatless air dryer.

As the air flows through the initial tower the desiccant absorbs moisture its pores capture and hold moisture and the dried air flows out of that tower. The dry air then flows through and regenerates desiccant. Generon heatless desiccant dryers consist of two towers containing a specialized material that absorbs the water vapor in the saturated compressed air stream. The purge air stream then carries the desorbed water out of the dryer.

Pressure dewpoint of 40 f 40 c and flowrate of 10 6000 scfm depending on model. Blower purge dryers use a combination of air from an external blower heat and minimal compressed air. How this happens depends on the type of desiccant dryer. The simple technology of heatless dryers divert a portion of dried compressed air to an off line tower.

Complete range of twin tower desiccant air dryers regenerative air dryer and other products for al industrial applications. One tower the initial tower dries the air while the other tower is re generated. Pressure swing dryers are often called heaterless or heatless dryers because no outside heat is added for the regeneration of the desiccant. The standard cycle time for a heaterless air dryer is 10 minutes for a 40 f dewpoint.

10 6000 scfm standard dewpoint of 40 f. Other variations exist for varied dewpoints. Hl heatless desiccant dryers use twin desiccant towers with strategically positioned valves to dry compressed air. Parker airtek tw series heatless twin tower desiccant air dryers remove contaminants in compressed air systems using pressure swing adsorption psa technology.

Heatless dryers use only compressed air as a purge. Pressure dewpoint of 40 f 40 c and flowrate of 10 6000 scfm depending on model. The amount of time that the saturated air remains in contact with the adsorption material dictates the output air dew point dryness of the product. A typical heatless dryer includes two towers filled with desiccant activated alumina or molecular sieve.

To do this the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off. We are leading supplier for heatless air dryer compressed air dryer.
