HR Series “Mini-Flow” Heatless Regenerative Dryers
Extremely dry air for point of use and OEM applications.
Compressed air dryers HR- through HR-7 are compact, simple to install, and easy to maintain. These dryers deliver a -40°F pressure dew point to protect pneumatic equipment and processes from the harmful and costly effects of compressed air moisture. In critical applications, HR Series dryers can deliver a -100°F pressure dew point.
Each HR Series dryer has advanced purge savings capability to minimize the waste of valuable compressed air. When the dryer is wired directly to an air compressor pressure switch or to auxiliary contacts, the dryer purge valves will open/close in parallel with the loading/unloading of the air compressor or point-of use process. Stored memory in the dryer controller resumes the dryer cycling at the point where it left off.
Models HR-1 through HR-7 are ideal for:
• Laboratories
• Gas generators
• OEM applications
• Critical points of use
• Protecting outdoor air lines
