ColdWave™ Energy Savings Refrigerated Dryers

The HES Series features groundbreaking technologies for the refrigerated compressed air dryer industry.
Digital Evaporator Technology continues the Hankison tradition of stable 38°F (3°C) dew points. Unlike anything in the industry, the HES Series, with patented Digital Evaporator Technology, offers energy saving advantages over traditional non-cycling, cycling and variable speed designs. Hankison technology platforms of heat exchangers, filtration and refrigeration are CSA and UL certified, represent the best value solution available for heavy-duty air demand profiles.

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
Patented 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
Hankison crafts quality refrigerated dryers engineered to match the specific air demands of your compressed air system.
