Alpha WA Chlorine Dioxide Generator
From healthcare estates to food processing, industrial plants and commercial buildings, the Alpha WA Chlorine Dioxide Generator is engineered for performance and uptime. Proportional control from a pulsed water meter tracks real-time flow maintains consistent chlorine dioxide (ClO2) residuals – no guesswork, no overdosing. An in-line reaction chamber generates ClO2 on demand, avoiding bulk storage and reducing risks to operators and the environment. Its small footprint and straightforward installation minimise downtime and keep sites compliant and operational. The Alpha WA integrates with industry-standard onsite BMS for centralised automation and alarm handling. Paired with 5G Scotmas Insite, users gain live dashboards, trend plotting, comprehensive data logging, and actionable notification to support compliance. With multiple safety interlocks, the Alpha WA provides tighter dosing control, clearer performance data, and dependable ClO2 delivery directly to the main line or storage tank.
