Donaldson Company announced the introduction of the Ultrapac™ HL Heatless Desiccant Dryer to the North American market.
The compressed air dryer, manufactured in the United States, is designed to deliver high‑purity compressed air with dew points as low as -40°F (-40°C) and down to -95°F (-71°C) on select configurations. With airflow capacities ranging from approximately 150 to 850 m³/h (90 to 500 scfm), the dryer can be configured to meet a wide range of system sizes and performance needs.
“The compressed air dryer is designed to support ISO 8753-1 air quality requirements,” said Marc Straub, Technical Product Specialist, Donaldson. “This launch reinforces our ability to support customers locally while leveraging Donaldson’s global engineering knowledge.”
The compressed air dryer’s heatless regeneration design eliminates the need for external heaters. Dewpoint is used as the trigger to initiate the regeneration process, delivering optimal drying performance while maximizing energy efficiency and cost savings. This technology helps manufacturers protect downstream equipment, maintain process integrity and improve overall system reliability.
