Twin Tower Heatless Air Dryer

Heatless dryers use only compressed air as a purge.

Twin tower heatless air dryer.

The standard cycle time for a heaterless air dryer is 10 minutes for a 40 f dewpoint. Generon heatless desiccant dryers consist of two towers containing a specialized material that absorbs the water vapor in the saturated compressed air stream. 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. To do this the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off.

Pressure dewpoint of 40 f 40 c and flowrate of 10 6000 scfm depending on model. Complete range of twin tower desiccant air dryers regenerative air dryer and other products for al industrial applications. Parker airtek tw series heatless twin tower desiccant air dryers remove contaminants in compressed air systems using pressure swing adsorption psa technology. 10 6000 scfm standard dewpoint of 40 f.

Parker airtek tw series heatless twin tower desiccant air dryers remove contaminants in compressed air systems using pressure swing adsorption psa technology. 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. Pressure swing dryers are often called heaterless or heatless dryers because no outside heat is added for the regeneration of the desiccant. Although operating costs run higher than the heated desiccant dryers the hl series requires the lowest capital investment.

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. A typical heatless dryer includes two towers filled with desiccant activated alumina or molecular sieve. Hl heatless desiccant dryers use twin desiccant towers with strategically positioned valves to dry compressed air. Blower purge dryers use a combination of air from an external blower heat and minimal compressed air.

One tower the initial tower dries the air while the other tower is re generated. Other variations exist for varied dewpoints. Parker zander kta series heatless twin tower desiccant air dryers effectively remove contaminants in compressed air systems using pressure swing adsorption psa technology. The purge air stream then carries the desorbed water out of the dryer.

The simple technology of heatless dryers divert a portion of dried compressed air to an off line tower. The dry air then flows through and regenerates desiccant.
