The ARC-PCO cell in the DXB 100 is key to keeping your cannabis facility protected 24/7 from harmful airborne contaminants like mold spores and mildew. It uses UV light to activate a special catalyst that produces hydrogen peroxide vapor (H2O2), breaking down these pollutants to ensure ongoing protection. However, for the DXB 100 to maintain its effectiveness, the PCO cell must be replaced annually. Over time, the cell wears out and can’t neutralize contaminants as efficiently. By replacing the cell every year, you ensure that your system continues to provide full protection, helping you stay compliant with microbial testing standards and keep your facility protected.
