The Hankison 750 scfm HHS Series Heatless Desiccant Air Dryer is a premium-grade industrial solution designed for applications with low dew point requirements such as pharmaceutical manufacturing, laboratories, hospitals, microelectronics, and more. With automatic energy savings controls, ISO 8573.1 quality classes compliance, and specialized SensaTherm® technology, this dryer offers consistent outlet pressure dew points, large desiccant beds for optimal contact time, and a range of integrated filtration options for enhanced performance and efficiency. Its advanced design, precision performance features, and industry-specific certifications make it a reliable choice for critical compressed air applications.
Product Specifications
Advantages
Temperature transducers (thermistors) are used as sensing devices. They are simpler, more reliable and rugged than those others use.Sensors require no calibration.The system is based on saving the heat of adsorption, towers switch before heat's lost maximizing purge air efficiency and minimizing the amount of purge air required.
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.
Application Specific Designs Match Performance By Demand
Three user selectable designs engineered to balance economy and performance.Ideal for applications that operate with a large swing in air demands due to variations in production scheduling or shifts of operation. Some applications operate at a fraction of the flow of the compressor due to air system efficiency improvements. Some applications operate continuously at-or-near full capacity.

Automatic Sensatherm Energy Savings
Hankison®'s HHS Series with patented SensaTherm® automatically matches purge air to plant air demand. This ensures maximum performance as the saved energy goes right to your bottom line.When operating at reduced capacity, the on-line drying tower remains active longer, until its full drying capacity is utilized. Desiccant bed temperature changes are constantly monitored within each tower to precisely manage drying times and reduce purge air consumption.SensaTherm® also measures the increase in desiccant bed temperature (heat of adsorption) during the drying stage and the decrease in desiccant bed temperature (heat of desorption) during the regeneration stage. These temperature changes are accurate indicators of the moisture load on the dryer. This data is interpreted by microprocessor based controls to determine how long a tower stays on-line during the drying stage.

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.
