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.
