Deltech ZP750, 750 SCFM, Desiccant Air Dryer

The Deltech ZP750 blower purge regenerative desiccant air dryer is an economical and reliable way to dry compressed air to dew points below the freezing point of water. The Deltech ZP series lowers the dew point of compressed air by absorbing the water vapor present in the compressed air onto the surface of the desiccant. Absorption continues until equilibrium is reached between the partial pressure of the water vapor in the air and that on the surface of the desiccant. The dryer continuously processes compressed air by using two identical towers, each containing a desiccant bed. While one tower is on-stream drying, the other tower is off-stream being regenerated (reactivated, i.e. dried out). The towers are alternated on and off-stream so that dry desiccant is always in contact with the wet compressed air. In this way a continuous supply of dry air downstream of the dryer is possible.

The Deltech ZP series produces the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig. The ZP series features quiet, energy efficient high-capacity blowers and towers filled with high-grade activated alumina. The soft-seated check valves ensure tight shut-off and the low-watt density heater saves energy and prevents premature desiccant aging.
