Ultrapac™ HL-ALD / HL-MSD Heatless Desiccant Compressed Air Dryer

Ultrapac™ HL-ALD / HL-MSD heatless desiccant compressed air dryers benefit from decades of design and fabrication experience by Donaldson.

Our dryers are designed to consistently provide highly purified quality air with high energy efficiency in a flow range from 100 to 8,750 m³/h / 59 to 5,150 scfm at 7 bar g / 100 psig.

Operation is fully automatic with a guaranteed outlet dew point at one of two pre-selected settings: ALD, -40° C / -40° F pdp; MSD, -40°C to -70 °C / -40°F to -94° F pdp, depending on operating conditions and sizing.

All Ultrapac HL dryers are supplied with preinstalled pre-filters and after-filters using UltraPleat™ technology. The coalescing pre-filter is equipped with the Ultramat™ zero-loss condensate drain.

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

Features

• Purification package complete with pre-/afterfilter and condensate drain — Turnkey system, no additional installation required.

• Prefilter with electronic, level-controlled drain — No compressed air losses due to condensate removal means reduction in operating costs.

• Superplus models with Ultraconomy dewpoint control. Monitoring and control of dewpoint ensure full utilization of desiccant capacity and is the trigger to start regeneration process. High energy and cost saving opportunity as well as full drying performance control.

• All silicone free materials for silicone free compressed air.

• Easy access to all components due to open frame design.

• 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.

• Wide range of dryer flow capacities, connection sizes and dewpoint options matching to user requirements. Custom made solutions possible, matching exact customer requirements; no oversizing of compressors necessary.

• Comprehensive option package: Orifice by pressure, dewpoint signal 4…20 mA, tropical version, -70° dewpoint measuring system — Flexibility in application, well thought-out package for economical operation and safe system installation in the compressed air network.
