Regenerative Desiccant Air Dryers - HR-SERIES
Using Pressure Swing Adsorption (PSA) technology, the Twin Tower Engineering regenerative air dryers are designed to maximize the efficiency of the drying process. Ultra-Dry compressed air dew points of -40°F to better than -100°F can be achieved.
Features:
• Very dry outlet air to better than -100°F dew point
• Flow capacities of 3 SCFM to 50 SCFM
• 8 model sizes to match application requirements
• Max pressure 150 PSIG
• Compact and lightweight design requires less space
• Solid State timer with memory for energy savings
• Standard NEMA 4X Electrical Rating
• Fully repressurizing design for steady outlet pressure
• Fixed, self cleaning orifices for accurate purge control
• Standard non-plugging, non-corroding purge mufflers
Typical Dry Compressed Air Applications:
• Ozone Generators
• Environmental Chambers
• Dry Glove Boxes
• Pneumatic Automation Systems
• Dental Air Compressors
