AC 2650-4200 Series Refrigerated Air Dryer
2,649-4,238 SCFM
Cycling, Air or Water-Cooled

The AC 2650-4200 Cycling Series is Pneumatech’s premium refrigeration dryer range for higher flows with the lowest operational costs. All AC dryers are equipped with their proprietary energy saving algorithm, which reduces the energy consumption to the real load by real-time monitoring the ambient temperature and the pressure dewpoint. When there is less cooling required, the refrigerant compressor shuts off and power consumption is significantly reduced, with savings up to 50%.

The Purelogic™ is installed as standard on all dryers: it ensures maximum reliability by monitoring the most important parameters of the dryer and offers impressive control and monitoring capabilities, like internet-based visualization. The AC 650-2100 Series is available in both air-cooled and water-cooled versions.

Benefits & Features:
  • Premium energy efficiency
  • Strong performance & reliability
  • Air-cooled as well as water-cooled versions available
  • Optimal control and monitoring thanks to the Purelogic™ controller
  • Easy maintenance at low cost
