High Performance. Maximum Reliability. Low Profile Design 500 – 14,900 m3/h

The HRS model of heat regenerated adsorption dryers is the most energy efficient option, providing low operating costs as well as easy maintenance. With HRS dryers, the desorption and cooling in the system variation is accomplished with the ambient air drawn in by the blower.

HED / ALD / MSD heatless desiccant compressed air dryers benefit from decades of design and fabrication experience by Donaldson. 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.

The Ultrapac™ Smart is a compressed air treatment system that combines multiple steps to achieve pure compressed air. It includes pre-filtration, heatless regenerated adsorption drying, fine filtration, and condensate removal. The compact stand-alone is a plug & play solution.

The CD-Series refrigerant dryers are carefully selected depending on working conditions with continuous dew point monitoring enabling reliable operation with the lowest possible pressure losses and running costs. Offering a wide range of kW of airflows.

Engineered for maximum reliability, long life, and easy service access.

ATVT dryers provide a constant outlet dewpoint in accordance with ISO8573 1
