VF and 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 VF Compact 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 dryers (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 dryers (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.

High –Capacity Cycling Refrigerated Compressed Air Dryers
The Donaldson RTM high-capacity cycling refrigerated compressed air dryers use multiple compressors with defined loading/unloading capacities and a thermal mass storage medium for energy-efficient operation. These dryers are ideally suited when large air volumes need to be dried to a reliable and constant dewpoint.

RFC and DVF Cycling Refrigerated Compressed Air Dryers
Energy efficient operation is of paramount importance to any industrial machine and the process it supports. The RFC dryer line, with Ultrapulse control, and the DVF digital scroll series, offer the latest in energy-saving technology up to 2,000 cfm.
The Donaldson RFC Series dryers (200-650 cfm) operate a microprocessor-based controller to turn the refrigerant compressor on and off based on actual load conditions. The controller has been programmed to not only measure and respond to critical operating parameters, but to track (up to 8 times per second) and anticipate demand. This ability to proactively encounter load changes and adjust the operating cycle accordingly sets the RFC series dryers apart from the competition.
The Donaldson DVF Series Dryers (800-2,000 cfm) utilizes digital scroll compressors to modulate between 10% and 100% capacity. The microprocessor-controlled modulation provides a near linear power reduction when unloaded, which results in a highly consistent performance pattern during load variations. Using our patented Variable Flow aluminum block heat exchanger, the DVF dryers provide the high separation efficiency our customers have come to expect.
