Astralpool Halo Pro 18 Salt Chlorinator & Pool Automation Controller 20375 - Coming Soon

Astralpool Halo Pro 18 Salt Chlorinator & Pool Automation Controller 20375

Part Number: 20375

• Genuine Authorised Fluidra Dealer & Warranty Agent
• Coming Soon

Expected release: 2027. Halo Pro is a forthcoming new-generation platform and is not the same product as the current Astralpool Halo Chlor system. The information below is based on Fluidra's pre-launch material and will be updated when final documentation is released.

Astralpool Halo Pro sits at the top of Fluidra's new chlorination and automation range, above the Solo and Echo controllers. It combines 18 gram per hour salt chlorination with full pool automation, and is intended for installations where Echo's single-pool equipment control is not enough - combined pool and spa systems, additional pumps, water features and automated valves.

Automation and Equipment Control

• Built for combined pool and spa installations, coordinating equipment across multiple operating modes
• Valve actuator control for automated changeover between configurations such as pool and spa
• Additional pumps and pool features
• Bluetooth-connected peripheral modules that link back to the controller, so automation is not limited to equipment wired directly into the chlorinator
• Compatible with Fluidra's Bluetooth filter-pressure sensor, which sets a clean-filter baseline and flags when pressure has risen enough to warrant a clean or backwash

Water Chemistry Control

Halo Pro is built for closed-loop chemical control using pH and ORP (redox) sensing, so dosing responds to measured water chemistry. This is the main chemical difference from the Astralpool Echo, which doses acid to a programmed schedule without measuring actual pH. Where the controller needs to react to real readings rather than dose a set amount, Halo Pro is the correct system.

Specifications

• Chlorine output: 18 grams per hour
• Designed around a recommended salinity of approximately 4,000 ppm
• Self-cleaning cell with WWDG technology
• Connected-device security support: to 31 December 2030

Pool volume ratings, dimensions, electrical ratings, pump and lighting compatibility, cell specifications, warranty terms and pricing have not yet been published by Fluidra.

Halo Pro or Halo Chlor?

Halo Pro (20375, 20376, 20377, 20378) is a new platform with its own product numbers, controller architecture and Bluetooth peripherals. It is separate from the current Halo Chlor range (20385, 20386, 20387, 20388), which remains available now. Parts, compatibility and installation requirements are not interchangeable between the two.
