AstralPool RolaChem RC9 100/GPO ORP & pH Controller for Automatic Monitoring and Dosing with GPO Acid Output

Managing water chemistry across larger pools can become increasingly demanding as bather loads, weather conditions and sanitiser demand fluctuate throughout the day. The AstralPool RolaChem RC9 100/GPO is designed to automate this process by continuously monitoring and controlling both sanitiser and pH levels, helping maintain clean, balanced water while reducing the need for ongoing manual chemical adjustment. Suitable for pools up to 250,000 litres, the controller assists in maintaining a healthy and safe swimming environment with less day-to-day intervention.

Chemical treatment capacity is provided through an integrated 100 RPM chlorine pump, while a dedicated GPO output is available for acid dosing control. By managing sanitiser and pH together, the controller helps maintain the conditions required for effective sanitiser performance. Maintaining correct pH balance allows sanitiser to work more efficiently, which can contribute to lower sanitiser consumption and more consistent water quality.

Continuous monitoring is achieved through sanitiser and pH sensors equipped with inbuilt amplifiers that detect and process low-level water chemistry signals. Information from both sensors is interpreted by the controller, allowing dosing requirements to be adjusted automatically as pool conditions change. This ongoing feedback helps maintain target water conditions without relying solely on manual testing and correction.

Automated control not only simplifies routine pool care but also helps reduce the common effects of poorly balanced water. By keeping sanitiser activity and pH levels under closer control, the RC9 can help minimise red eyes and skin irritation while reducing maintenance requirements. The result is a more consistent approach to pool water management with fewer manual adjustments required throughout the season.
