Additional Information

Additional Information

 N/A Air treatment manufacturers are challenged to design equipment that consumes less energy while operating at reduced load. Hankison® HES Series Refrigerated Compressed Air Dryers are the ideal solution!

Sustainable energy saving solutions are the driving principle behind Hankison® product designs. The HES Series lowers power costs and improves productivity by matching power consumption to compressed air demand.

Load Matching Performance

Load Matching Performance

 N/A Non-cycling dryers operate with the refrigeration compressor running continuously, regardless of inlet load conditions. Minimal energy savings are realized from 100% down to 0% inlet air load.

HES Series dryers automatically cycle (on/off) the refrigeration compressor in response to inlet load conditions. As the inlet air load is reduced, the power requirement to dry the air is matched in proportion to the demand.

For example, at 60% inlet air load, a non-cycling dryer consumes 96% of the full load power consumption, a 4% energy savings. By comparison, at 60% inlet air load, an HES Series dryer consumes 62% of the full load power consumption, a 38% energy savings.

The load matching design reduces power costs and saves energy. The example below provides annual HES energy savings with respect to non-cycling designs.

Delivers ISO 8573-1 Quality Class Air

Delivers ISO 8573-1 Quality Class Air

 N/A The International Organization for Standardization (ISO) identified three forms of contamination as common in compressed air systems - solid particles, water and oil. ISO Standard 8573-1: 2010 categorizes each contaminant and assigns a quality class, ranging from Class 0, the highest purity level, to Class 9, the most relaxed.

The HES Series effectively removes all three contaminant forms in a single air treatment system.

Delivers Performance, Sustainability and Safety

Delivers Performance, Sustainability and Safety

 N/A The Drying Process-Compressed Air Circuit:
  1. Warm, saturated compressed air enters the dryer through the inlet pipe connection.
  2. Air travels through the air-to-air heat exchanger and the glycol-to-air heat exchanger. Propylene glycol surrounds the passages and cools the air to the desired pressure dew point.
  3. Moisture, solid particulates and oil aerosols are removed by the filter/separator. A no-air-loss condensate drain discharges contaminants from the system.
  4. Dry, filtered air exits the dryer for use.


    5. The Cooling Process-Glycol Circuit:
  5. Glycol exits the air-to-glycol heat exchanger and then enters the glycol storage tank.
  6. A circulation pump continuously moves the thermal medium throughout the circuit.
  7. A thermal sensor monitors the glycol temperature and turns the refrigeration compressor off whenever the glycol is cooled to its lowest temperature. The cooling medium continues to dry the air. After the medium warms up, the thermal sensor restarts the refrigeration compressor.
  8. The glycol-to-refrigerant heat exchanger chills the thermal media and travels back to the air-to-glycol heat exchanger.

Our Commitment to You

Third Party Performance Certification

 N/A Hankison® is a member of the Compressed Air and Gas Institute (CAGI), a non-profit organization that develops and publishes standards serving the compressed air industry.

CAGI members may participate in an independently controlled Performance Verification Program for refrigerated air dryers in the flow range of 90 scfm to 675 scfm. Certification through a third party laboratory provides end-users an industry accepted basis for comparison of refrigerated air dryer performance and selection.

Standardized performance data sheets are posted on the Hankison® website.
