Air Dryers Pioneer ( R& ADR Series)

Since Pioneer founding in 1980, nearly half of their business has been building custom equipment to meet the strictest specifications. The engineering staff and well-equipped factory are prepared to meet and exceed your expectations. From vacuum to 10,000 PSIG; 10 to 15,000 SCFM; air or corrosive and flammable gases. If your application has to do with drying and cleaning compressed air or gas, chances are Pioneer is your best choice.



  1. Removable insulation

  2. Electric automatic drain

  3. Lower dew points

  4. Efficient centrifugle separator; chilled separator standard in R75/ADR40 and up

  5. Easy access cabinets - standard up to R600A/W, ADR300A/W; optional in larger sizes

  6. NEMA1 control panel standard; NEMA 4, 7, or 12 and custom control panels available

  7. Lower pressure drops - in a 100 PSIG/6.89 bargpressure drop saves 1% in energy costs. Lowe pressure drops are inherent in Pioneer heat exchangers

  8. Compact design - Triple-tube heat exchanger design reduces floor space requirements and shipping costs. The air-air requirements exchanger also reduces refrigeration horsepower and dryer size

  9. Environmentally safer refrigerant R-134a and R-22 standard

  10. Dew point adjustment


Protect Your Equipment and Save Money

A typical Pioneer dryer pays for itself in less than a year by reducing or eliminating maintenance costs and down time. In Pioneer refrigerated dryer models P30A/W(ADR15 A/W) and larger, the warm, moist air (or gas) enters the air-air heat exchange where it is precooled by the outgoing cool air. Precooling allows the use of a smaller refrigeration system and lowers the cost of drying. Further cooling of the air to a 350°F(20°C) range is accomplished by the refrigeration. Cooling the air causes the moisture vapor to condense. The condensation is separated by highly efficient separation techniques and drained by automatic drains.




For compressors with after coolers, designed for inlet temperature up to 250°F/121°C

  • Rust-free copper and brass heat exchanger provide maximum heat transfer

  • Patented Triple-Tube Heat Exchangers provide lower, more consistent dew points with lower pressure drops (R75A/W and up)

  • Standard Micromonitor R75A/W and up

  • Automatic drain system with cleanable y-strainer and isolation valve



For compressors without after coolers, designed for inlet temperature up to 250°F/121°C

  • 10 - 20% increase in actual volume by reheating the out going air with the incoming warm air

  • Lower pressure drop - 2 PSIG/0.14 barg compared to 8 PSIG/0.55 barg in a typical after cooler, separator, and dryer installation

  • Air cooled models eliminate water usage

  • Higher temperatures and lower relative humidity reduce likelihood of freeze-up in downstream air lines

  • Simplified installation
