Cycling Refrigerated Compressed Air Dryers Consistently Deliver Premium Air at Low Cost

Donaldson Company (NYSE:DCI), a leading, worldwide manufacturer of filtration systems and parts, offers manufacturers the industry's preferred line of cycling refrigerated compressed air dryers that reliably provide energy-efficient operations with patented technology, flexible design, and intelligent control. Intelligent control logic combined with high quality components and expertise in real-world operating conditions enable Donaldson cycling refrigerated compressed air dryers to provide consistent premium air at the lowest possible cost. Specific cycling dryer features include: – Microprocessor-based controllers programmed to measure and respond to critical operating parameters and anticipate demand, which allows the Donaldson RFC Series dryer (200 – 650 scfm) to proactively encounter load changes and adjust operating cycle to avoid dew point spikes. – The Ultrapulse controller offers modes of operation, depending on the needs of the process and changes in ambient conditions: Standard Mode (38ºF pressure dew point (pdp)), Summer Mode (45ºF pdp), and Flex Mode developed to address applications set at relative humidity levels versus a set dew point. All prevent liquid condensation from forming in the piping system and provide increased energy savings. – Utilizing digital scroll technology, Donaldson's DVF Series dryer (800 – 2,000 scfm) modulates between 10% and 100% capacity thereby increasing efficiency and reliability while reducing vibration during operation.  Donaldson uses only R-134a, an environment-friendly, 100% chlorine-free refrigerant as standard in all refrigerated compressed air dryers. The R-134a is a one-blend refrigerant, easy to service and consistent in performance. All Donaldson dryers are designed to provide the highest level of value available in the industry – reliable performance to CAGI ADF 100 specifications while consuming the lowest amount of energy possible. Donaldson has the engineering, manufacturing capability and experience to design dryer systems of any size – with pressure up to 10,000 psig and volumes up to 50,000 scfm. Their full line of products includes non-cycling and cycling refrigerated dryers, heated and heatless regenerative desiccant dryers, industrial filters and separators, and process water chillers.
