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.

Controller Features

Choice of four fixed cycle operating modes corresponding to ISO 8573.1 Air Quality Classes
Choice of eight Purge Economizer Energy Savings settings
Switches for On/Off, Alarm and Service reminder reset
Operational LED lights for power-on, tower status, valve status, and tower pressure
Alarm LED for valve switching failure
RS-232 communications port is standard
Service reminder LED lights for filters and drains, valves and desiccant

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.

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.
