Precision Performance

Industry-Leading Design
  • Consistent outlet pressure dew points
  • Premium grade desiccant beads enhance surface area and have high crush strength
  • Large desiccant beds ensure 4.8 seconds of contact time
  • Large flow diffusers ensure even flow distribution through the bed and eliminate channeling
  • Towers are designed to prevent fluidization of the desiccant
  • Up-flow drying allows water and heavy contaminants to drop out of the air stream
  • Simple discharge of contaminants
  • Cleanable stainless steel flow diffusers/support screens
  • Separate fill and drain ports for ease of desiccant replacement

Integrated Filtration
  • Optional pre-filter and after-filter packages, featuring Hankison® NGF Series filters, can be pre-installed at the
    • Grade SF and Grade HF pre-filters are recommended for -40 ºF to 38 ºF (-40 ºC to 3 ºC) dew points
    • Grade PF and Grade UF pre-filters are recommended for -100 ºF (-73 ºC) dew points
    • Grade PF and Grade CF are the recommended after-filters

Precision AccuShift™ Switching Valves
  • Automatically shift to the low pressure side of the circuit to control process flow
  • Position memory ensures drying continues even without power
  • 5 year AccuShift™ valve replacement warranty
  • Three-way pilot operated solenoid valves manage the pilot air flow to direct the purge/repressurization valves
  • Purge pressure adjustment valve
    • 1 Dryer must be protected by properly sized Hankison® prefilter. Parts and labor covered through first year of warranty, parts only in second through fifth years.

Engineered-to-Order Options
  • High dew point alarm which includes light and voltage free contacts for remote alarm
  • Dew point monitor, includes digital display, voltage-free contacts and recorder output
  • Low ambient packages, epoxy paint, severe environment protection
  • Oil-free packages with integrated activated carbon towers

Safety Built to Code
  • Pressure vessels are CRN and ASME Certified
  • Heavy-duty mufflers for quiet operation
  • NEMA 4 electrical construction is standard
  • Pressure relief valves are standard


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.

-40 ºF Dew Point Performance
Hankison®'s HHE Series is engineered to address the need for raw performance and value. This traditional design uses a simple timer to alternate the flow between the two towers filled with premium grade desiccant. 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. While the on-line tower is drying the air stream, the off-line tower purges a fixed amount of compressed air to dry the bed and prepares it for the next drying cycle.


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.


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.
