The PDM Indoor Space Sterilization & Deodorization System utilizes ozone for effective indoor air purification. It eliminates odors via oxidation and sterilizes by destroying bacteria and viruses, reducing infection risks. The system integrates a UV ozone lamp generator, an ozone concentration monitoring sensor, and an automatic control system. This ensures safety by continuously monitoring ozone levels and automatically stopping generation if concentrations exceed strict safety standards (e.g., Japan's 0.05 ppm indoor environmental standard), resuming when safe. PSE mark compliant, units are flexibly installed, processing 3-4 cubic meters of air per minute with 45W power consumption per unit. This offers a safe and efficient solution for clean, odor-free indoor environments.
