RD Refrigerated Compressed Air Dryers

For air line protection, Van Air RD Series refrigerated compressed air dryers combine the newest technology in heat transfer with a proven refrigeration system to keep your pneumatic equipment running at peak efficiency. Providing a constant 35 - 38° F dew point and low initial cost, an RD Series refrigerated air dryer provides the best combination of performance and economy.

All the components of an RD Series refrigerated compressed air dry are housed in a powder coated cabinet to ensure a long useful life. All units include a refrigerant analyzer light, non-cycling refrigerant compressors, a compressor run light, and a built-in drain.

A capacity control valve allows the dryer to operate efficiently at low loads by preventing heat exchanger freeze-ups. The control valve also keeps the dew point steady when the air flow changes. For maximum performance, it is recommended that a pre-filter be installed.

All standard models have immediate availability. Contact us today at 1-800-840-9906 or Email Us to purchase an RD Series dryer or to discuss how Van Air compressed air dryers and equipment can help you with your compressed air drying needs.
