HES Series ColdWave™

ColdWave™ Energy Savings Refrigerated Dryers. HV Series & HES Series. High-Volume Refrigerated Dryers

Rapid Return-On-Investment (ROI)
The HES Series is designed to provide a rapid return on investment by:

  • Reducing the dryer’s energy consumption down to 9% (91% savings) at 0% load
  • Precise matching of average air flow (heat load) with the required input kW power…No More…No Less
  • Qualifying for energy rebates offered by utility companies
  • Maintaining a stable 38°F (3°C) dew point with no dew point spikes

The HES Series Refrigeration System
Digital Evaporator Technology controls the actions of the three core components in the refrigeration system (Digital Evaporator, Digital Control board, Digital Scroll refrigeration compressor) to provide true load-matching energy savings while maintaining a very stable 38°F (3°C) dew point.

Air Treatment Station Features:

  • HF Series Grade 9 Coalescing Separator/Filter
  • Integrated HF Series Grade 5 Cold Coalescing Oil Removal Filter (optional)
  • Dedicated Electronic demand drain(s) for the integrated separator/filter and for the optional oil removal filter
  • RS-232 Communication Port Space savings with dryer (no pre-filter required) and after-filters all in one cabin

H Series

Consistent dewpoint of 38°F to 50°F, 3°C to 10°C
H Series high capacity refrigerated air dryer’s automatic temperature control maintains consistent dewpoint temperature across a wide range of operating conditions.


HIT Series

High Inlet Temperature Refrigerated Dryers

  • Cools, accepts high temperature air to 180°F, 82°C directly from your air compressor, no separate aftercooler and separator required
  • Dries, removes moisture, eliminates troublesome water from downstream air lines and equipment
  • Cleans…an integral 3 micron filter removes solid contaminants and 60% of oil aerosols. (For virtually oil free air, Hankison high efficiency oil removal filters are available.)

HPET Series

Hankison high pressure compressed air dryers and filters form an important part of PET blow molding …
