AstralPool RolaChem RC9 5/5 ORP & pH Controller for Pool Chemistry Control with Programmable Control

Pool water chemistry is constantly changing as weather conditions shift and swimmer activity increases. The AstralPool RolaChem RC9 5/5 is designed to automatically manage both sanitiser activity and pH balance, helping maintain clear, comfortable water without the continual adjustments often associated with manual chemical treatment. Suitable for pools up to 45,000 litres, it delivers ongoing water quality management through a fully integrated monitoring and dosing platform.

Unlike systems that control only a single parameter, the RC9 5/5 simultaneously monitors ORP and pH values to maintain the relationship between sanitiser effectiveness and water balance. Built-in 5 RPM chlorine and acid dosing pumps work together with proportional control software, allowing chemical additions to increase or decrease according to actual pool demand rather than relying on fixed dosing schedules.

Accurate water analysis is achieved through dedicated ORP and pH sensors featuring integral amplifiers and high-level shielding to minimise signal interference. As operating conditions change throughout the day, the controller continuously interprets incoming readings and adjusts dosing accordingly. This responsive approach helps reduce unnecessary chemical usage while supporting a healthier swimming environment.

Beyond water chemistry management, the controller also provides programmable filter pump control and a dedicated spa mode that automatically modifies dosing rates when a spa is isolated from the main pool. Compatibility with Viron Connect enables integration with broader pool automation systems, creating a more streamlined and connected approach to pool ownership.

• Combined ORP and pH management platform within a single controller.
• Integrated peristaltic chlorine and acid dosing pumps eliminate the need for separate dosing equipment.
• Proportional dosing operation adjusts chemical feed duration according to measured demand.
• ORP and pH sensors incorporate integral amplifiers for enhanced signal processing.
• High-level sensor shielding assists in minimising electrical interference.
• Programmable filter pump control supports coordinated pool operation.
• Automatic spa mode modifies dosing behaviour when operating an isolated spa.
• Viron Connect compatibility allows expanded automation and control integration.

The controller is backed by a 3 year warranty, with pH and chlorine sensors, dosing motor/gearbox assemblies, and associated tubes and fittings covered for 1 year.
