HED / ALD / MSD Heatless Desiccant Compressed Air Dryers

Our dryers are designed to consistently provide quality air with high energy efficiency in a flow range from 5 to 8,750 m³/h / 3 to 5,150 scfm at 7 bar g / 100 psig. 

Operation is fully automatic with a guaranteed outlet dew point at one of three pre-selected settings: HED, -20° C / -4° F pdp; ALD, -40° C / -40° F pdp; MSD, -70 °C / -94° F pdp. Each dryer in the 5 - 1000 m³/h / 3 - 588 scfm flow range is enclosed in a protective cabinet with easy-to-remove panels.

All Ultrapac Classic dryers are supplied with preinstalled pre-filters and after-filters. The coalescing pre-filter is equipped with the Ultramat® zero-losscondensate drain.

The compact design of Ultrapac dryers takes up a minimum of floor space.

Features

• Purification package complete with pre-afterfilter and condensate drain — Turnkey system, no additional installation required, all components technically perfectly matched to each other. 
  
  
• Prefilter with electronic, level-controlled drain — No compressor air losses due to condensate removal means reduction in operating costs.
  
  
• All dryers in cabinet construction — Optimal protection against dirt and mechanical damage.
  
  
• Generous dimensioned filters — Large filtration surface means lower pressure drop and lower operating costs. 
  
  
• Display of operating status by LED — High operating safety, since all operating status can be detected easily at any time. 
  
  
• Intermittent operation standard — Link between dryer and compressor possible on central applications resulting in compressed air savings.
  
  
• All sizes available, matched to the compressor flows, with 3 pressure dewpoints each, for choice — Custom made solutions possible, matching exact customer requirements; no oversizing of compressors neccessary.
  
  
• Comprehensive option package: Dewpoint depending control, startup device, bypass, pneumatics control, change-over control etc. — Flexibility in application, well thought-out package for economical operation and safe system installation in the compressed air network.
