Regenerative Desiccant Dryers
Donaldson Compressed Air & Gas designs and manufacturers heatless desiccant dryer using innovative technologies – focused on energy efficient operation and reliable performance.

Ultrapac 2000® Regenerative Heatless Desiccant Dryers The Donaldson Ultrapac 2000 (3-60 scfm) heatless adsorption dryers is a complete purification system including pre-filter, dryer, after-filter, control system and automatic condensate drain and silencer. All components are factory sealed requiring minimum installation and almost instant start-up. This modular design of mechanical and electronic components reduces downtime with modular repair/replacement capability, and the compact footprint saves valuable space on the plant floor.

Membrane Dryers
Donaldson Compressed Air & Gas manufactures a complete line of membrane dryers to meet your specific air quality requirements and system solutions. The modular design offers individual customer solutions, and therefore guarantees highest flexibility and efficiency.

VarioDry Membrane Air Dryer Donaldson VarioDry membrane dryers are ideally suited for point-of-use applications that require compressed air at a higher purity level than that provided by the plant air system. When operating at full capacity, VarioDry membrane dryers reduce, or suppress, the dew point of inlet air by 36ºF. Dew point suppression will go up as flow is reduced. Our membrane dryers have no moving parts, do not require electrical power and are constructed with materials highly resistant to corrosion.

FRL Modular Membrane Air Dryer Donaldson FRL modular dryers utilize VarioDry membrane modules and include integrated prefiltration and pressure regulation. Where required, an integrated activated carbon filter can be added for hydrocarbon vapor removal.
