Multiple-output process controller Blu-Sentinel™

programmablemulti-channelprobe

Short description
Chemical controller designed for commercial recreational water applications, providing precise measurement and automated dosing control for pools and spas.

Description
A unique collaboration between Neptune-Benson and Evoqua's Wallace & Tiernan® brands, the Blu-Sentinel™ chemical controller combines high-resolution measurement with process control for commercial pool water treatment. It integrates Strantrol® High Resolution Redox (HRR) and pH sensors for accurate and reliable monitoring. The system handles shock chlorination and economic mode operation and implements the CEDOX control algorithm to optimize disinfection and chemical use. It supports dosing pumps and relay-controlled feeders, chlorine gas feed control, on-site electrochlorination units, and provides control signals for UV systems, flocculation and activated carbon slurry feed systems.

Benefits

• Maintains clear, balanced pool and spa water 24/7 for commercial facilities
• Reduces chemical consumption up to 30% and helps extend the life of pool surfaces and equipment
• Fast return on investment through lower operating and maintenance costs
• Designed for hospitality, health clubs and municipal aquatic facilities
• Custom flow cell improves sensor sampling accuracy and prolongs sensor lifetime
