Twin Tower Heatless Air Dryer

Other variations exist for varied dewpoints.

Twin tower heatless air dryer.

Pressure swing dryers are often called heaterless or heatless dryers because no outside heat is added for the regeneration of the desiccant. Parker zander kta series heatless twin tower desiccant air dryers effectively remove contaminants in compressed air systems using pressure swing adsorption psa technology. Although operating costs run higher than the heated desiccant dryers the hl series requires the lowest capital investment. 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. How this happens depends on the type of desiccant dryer. 10 6000 scfm standard dewpoint of 40 f. 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.

To do this the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off. One tower the initial tower dries the air while the other tower is re generated. The standard cycle time for a heaterless air dryer is 10 minutes for a 40 f dewpoint. Hl heatless desiccant dryers use twin desiccant towers with strategically positioned valves to dry compressed air.

Complete range of twin tower desiccant air dryers regenerative air dryer and other products for al industrial applications. Pressure dewpoint of 40 f 40 c and flowrate of 10 6000 scfm depending on model. Heatless desiccant air dryers hhs series hhl series and hhe series 40 to 5400 scfm 68 to 9175 nm 3 h hankison s heatless desiccant dryers the hhs hhl hhe series utilizing twin towers filled with premium grade activated alumina hankison heatless dryers are available with three application specific control systems. Parker airtek tw series heatless twin tower desiccant air dryers remove contaminants in compressed air systems using pressure swing adsorption psa technology.

The dry air then flows through and regenerates desiccant. The purge air stream then carries the desorbed water out of the 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. A typical heatless dryer includes two towers filled with desiccant activated alumina or molecular sieve.

Generon heatless desiccant dryers consist of two towers containing a specialized material that absorbs the water vapor in the saturated compressed air stream.
