Description
🛠️ Tsunami Pure-20P Regenerative Dryer System (PN 21999-1020)
80 CFM of Ultra-Dry, Cold-Weather-Ready Air at –40°F Dew Point
The Tsunami Pure-20P Regenerative Dryer System (21999-1020) is engineered for industrial operations that demand reliable moisture removal in both standard and freezing environments. Purpose-built for 20 HP air compressor systems and rated for 80 CFM, this dryer delivers clean, ultra-dry compressed air with a consistent –40°F pressure dew point, making it ideal for applications where moisture simply cannot be tolerated.
Refrigerated dryers lose efficiency and begin to pass moisture once temperatures drop. The Pure-20P thrives where refrigerated dryers fail. Using a dual-tower regenerative design, the system automatically cycles every two minutes to maintain a stable dew point, even when ambient conditions fluctuate or fall below freezing. For powder coating, CNC machining, automotive finishing, laboratory equipment, and precision industrial processes, the Pure-20P provides dependable moisture protection.
At Compressed Air Advisors Online, America’s choice for compressed air solutions, we proudly recommend the Pure-20P for customers who need reliable, cold-weather-capable drying without compromise. Each system typically ships in 7 days or less from Minneapolis, ensuring fast turnaround for your operation.
