Product Specifications
Application Specific Designs How It Works
Phase 1 - Moist, filtered compressed air enters the pressurized on-line desiccant-filled drying Tower 1 through the AccuShift™ valve (A).Phase 2 - Up-flow drying enables the desiccant to strip the air stream of moisture. Clean, dry compressed air exits through AccuShift™ valve (B) to feed the air system.Phase 3 - When in regeneration mode, Tower 2 depressurizes to atmosphere through the muffler (C) when the valve (D) opens.Phase 4 - A portion of dry compressed air (purge air) is diverted before exiting (B) and passes through off-line Tower 2 and exits at valve (D) to desorb the moisture from the desiccant. Once desorbed, valve (D) closes and Tower 2 is repressurized.Phase 5 - At tower shift-over, valve (E) will open, causing AccuShift™ Valves (A & B) to shift.Phase 6 - Tower 2 will be placed on-line to dry the bed. Operations will switch and Tower 1 will be regenerated.

Dedicated To Excellence
Since 1948, compressed air users around the world have relied on Hankison® to provide innovative compressed air treatment solutions for critical applications.Hankison® maintains a long standing reputation for manufacturing products that deliver superior performance, time proven reliability and optimal energy savings.Hankison® today is the preferred choice for providing clean, dry compressed air for the most challenging industries.
Four Dew Point Options Per Iso 8573 1 Air Quality Standards
Specifying a pressure dew point is not simple work for an engineer. Hankison® Heatless dryer designs allow you to optimize performance and dew points in the field to adapt to your environment and meet the following ISO 8573-1 Classes of air quality.
Inlet Flow
Inlet flow capacities are established in accordance with CAGI (Compressed Air and Gas Institute) standard ADF-200: Inlet air pressure 100 psig (6.7 barg), inlet temperature saturated at 100 ºF (38 ºC). To determine inlet flow at pressures other than 100 psig (6.7 barg), multiply inlet flow at 100 psig (6.7 barg) from Product Specifications by the corresponding multiplier.

Selectable Purge Economizer Savings
HHL Series provides user selectable energy savings with tailored drying cycles designed to match your peak air demands.Reducing the amount of time the dryer spends purging in the regeneration cycle can save energy. Eight settings (0% to 70% in 10% increments) are furnished for users to lower the purge to match reduced air loads on the dryer. Each energy saving setting has an LED light which will illuminate when it is selected. Simply flip the switch to select the desired energy saving setting.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.
