AstralPool - UV-C Radiation Sensor for Heliox UV MP Systems - 4408070025

AstralPool – UV-C Radiation Sensor for Heliox UV MP Systems

This is a genuine AstralPool replacement UV-C radiation sensor designed for the Heliox UV MP range of medium-pressure UV disinfection systems used in commercial and public swimming pools. The sensor continuously measures UV-C intensity (mW/cm²) inside the reactor, providing the control unit with real-time data to maintain precise disinfection dosing. Replacing a faulty sensor restores accurate lamp power regulation and ensures the system continues to deliver the required UV-C dose.

How it works

The Heliox UV MP control system uses two key inputs to manage lamp power: the radiation level measured by this sensor and the current water flow rate. If UV-C output drops due to lamp ageing, water turbidity, or scaling, the controller reads the sensor signal and automatically adjusts lamp power to maintain the target dose of 60 mJ/cm². A failed or degraded sensor can prevent this closed-loop control from functioning correctly, potentially triggering radiation alarms and reducing disinfection efficiency.

Compatibility

This radiation sensor is a listed spare part for the full Heliox UV MP product range, covering models from 50 m³/h up to the largest high-wattage variants. It fits the following Fluidra/AstralPool exploded views: 52200 (Heliox UV MP 50), 52201 (UV MP 80), 52202 (UV MP 140), 52203 (UV MP 300), 52204 (UV MP 450), 52205 (UV MP 675), 58698, 58699, 58808, 58809, 58810, and 58811. Always verify your specific model and exploded view number before ordering.

Why genuine matters

AstralPool specifies the use of genuine OEM spare parts in all Heliox UV MP service documentation. A calibrated replacement sensor ensures the control unit receives accurate mW/cm² readings, preventing under- or over-dosing.
