SD, VF, AR Series Non-Cycling Refrigerated Compressed Air Dryers
Donaldson non-cycling refrigerated compressed air dryers are focused on reliable, constant dew point performance in all flow conditions. With its excellent heat transfer coefficients and extremely low pressure drop, these dryers will outperform the competition in protecting your compressed air systems, machinery, and tools.

The Donaldson SD Series dryers (10-40 cfm) combine energy efficient, reliable operation with a space-saving small footprint. The SD features an the integrated air-to-air exchanger, often only used in larger models, but standard feature in all Donaldson refrigerated air dryers.

The Donaldson VF Series (50-2,000 cfm) offers the highest efficiencies at varying flow conditions in a lightweight, compact design. No other dryer in the industry can offer the efficiency ratings achieved by the VF Series dryers in variable flow operations.

The Donaldson AR Series (2,500-10,000 cfm) stands for reliability and performance. Air-cooled and water-cooled designs are available, along with a number of customization options to exactly match the application requirements.

DHT Series High Inlet Temperature Refrigerated Compressed Air Dryers
The Donaldson DHT (20-125 cfm) high inlet temperature refrigerated compressed air dryers have been designed specifically for use with smaller air compressors that typically do not incorporate an aftercooler. The DHT dryers can accept compressed air up to a temperature of 250۫ F and provide clean dry air at the outlet.
