Compressed Air Dehydration Desiccant Dryers

Desiccant Dryers


Featured Product

HHL,HHS and HHE Series’ Heatless dryers utilizes twin towers filled with premium grade activated alumina and are available with 3 application specific control systems to meet the needs of industry with economy and performance.

HBP Series dryers improve air system efficiency by the use of a dedicated axial blower, instead of a percentage of dehydrated purge air, to regenerate the off-line desiccant tower.

Technology

Desiccant Drying

Desiccant dryers lower the dew point of compressed air by adsorbing the water vapor present in the compressed air onto the surface of the desiccant. Adsorption continues until equilibrium is reached between the partial pressure of the water vapor in the air and that on the surface of the desiccant. These dryers continuously process 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 down stream of the dryer is possible. The switching from one tower to the other is controlled by a solid-state controller on either a fixed time basis (standard) or a demand basis (optional).

HHS Series Automatic SensaTherm® Energy Savings

HHS Series with SensaTherm® automatically matches purge air use to the demand on the system. This ensures maximum performance as the energy saved goes right to your bottom line. Controller features vacuum fluorescent text display that communicates energy savings, operating mode and service reminders. Select from one of the four pressure dew point settings to optimize your savings for each season.

HHL Series Selectable Purge Economizer Savings

HHL Series provides user selectable energy savings. Tailor the drying cycles, to match your peak air demand, in 10 percent increments. In addition, this state-of-the-art controller offers four pressure dew point settings to further tune your savings and adapt the system to your environment.

HHE Series-40°F Dew Point Performance – Pure and Simple

HHE Series presents traditional heatless drying technology. Using a simple timer based controller, these are designed to deliver maximum value to applications that operate at or near full capacity. Automatic time controlled bed regeneration cycles offer consistent performance and economy of purchase.

HBP Series Blower Purge

HBP Series dryers improve air system efficiency by the use of a dedicated axial blower, instead of a percentage of dehydrated purge air, to regenerate the off-line desiccant tower. ISO 8573.1 Class 2 (-40°F/-40°C) dew point performance is guaranteed. HBP Series compressed air dryers will produce 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.
