Refrigerated Dryers

The Importance of Clean, Dry Compressed Air
Water jeopardizes everything you want your compressed air system to do. It ruins product and fouls processes. Removing it is vital in order to protect both your equipment and your operations.

Sullair Refrigerated Air Dryers reliably remove harmful moisture and contaminants from compressed air, helping protect your compressed air system, machinery and downstream tools.

Refrigerated Dryer Types

  • Non-Cycling: Non-cycling dryers are ideal for running at full load because they maintain a constant energy consumption no matter the flow and air demand. Using a hot gas bypass, they maintain a consistent dew point and control the amount of refrigerant circulating through the dryer. 
  • Digital Scroll: Advanced digital scroll technology saves the highest amount of energy possible in a refrigerated air dryer — up to 91% while in operation. Communication with the system evaporator — via temperature probe — adjusts refrigeration capacity to the temperature exiting the dryer while maintaining a consistent dewpoint.

The next generation of Sullair Refrigerated Air Dryers focuses on high quality manufacturing standards, durable packaging and consistent, reliable dew point performance in all flow conditions.

Models vary by region. Please contact your Sullair sales representative for more details.
