Ingersoll Rand heatless and heated blower desiccant dryers—are engineered for easy access, maximum efficiency and long life. Ingersoll Rand desiccant dryers are designed to virtually eliminate costly production interruptions due to moisture. All of our dryers use twin desiccant towers and strategically positioned valves for drying compressed air. Switching valves are normally open, while purge valves are normally closed to allow air flow through the dryer in case of power loss. Strategically-placed filters that remove oil and contaminants ensure only clean, dried air exits the dryer. Every dryer features an IP54 package, providing increased protection of electrical components, controls and displays. Both heatless and heated blower dryers have several standard features to ensure high quality operation as well as options to customise dryers to fit the needs of your air system.
