Van Air Systems: refrigerated air drier
New RD Series refrigerated compressed air driers remove moisture from indoor air lines to reduce maintenance costs and keep pneumatic equipment running efficiently, the company says. The units provide a 35° to 38°F dewpoint and feature a non-cycling refrigerant compressor, R-22 refrigerant, and a hot-gas bypass valve to prevent heat exchanger freeze-ups at low loads and maintain a steady dewpoint when flows fluctuate. Models are available to handle flows of 10 through 150 scfm at 100 psig.
