The Dossi Automatic Tablet Feeders deliver consistent chlorine or bromine dosing without the hassle of daily checks or complex equipment. Ideal for private and public pools, they offer energy-free operation and are available in multiple capacities to suit all needs.\nWhat is the Dossi Automatic Tablet Feeder?\nThe Dossi Automatic Tablet Feeder is a chemical dosing device that uses slow-dissolving Trichlor or Bromine tablets to disinfect pool water. With models ranging from 3.5 kg to 30 kg in capacity, and installation options for in-line or off-line plumbing, Dossi feeders provide a reliable, autonomous solution for maintaining safe water quality. Designed for both residential and commercial use, they integrate easily with AstralPool’s control systems for full automation.", "description": "Key Benefits\n\nAutomated sanitation: Reliable chemical dosing for chlorine or bromine tablets\nEnergy-free operation: Works using water pressure or bypass flow—no electricity required\nVersatile installation: Choose between in-line (Venturi) or off-line (bypass) setups\nExtended autonomy: Larger models require fewer refills, perfect for busy owners or staff\nSafe and sealed: Locking lids, anti-return valves, and purge systems built in\nCompatible with controllers: Integrates with AstralPool Poolwatch and Easywatch systems\n\nMain Functions\nDossi feeders work by gradually dissolving Trichlor or Bromine tablets into the pool’s circulation line. In in-line models, water flows through the feeder (Venturi effect), while off-line models divert flow via a bypass with integrated valves. The dosing rate can be adjusted via control knobs, and tablets are stored safely inside until consumed. The system ensures continuous, hands-free disinfection day after day.\nTechnical Features\nConstruction & Design\n\nManufactured from chlorine- and bromine-resistant ABS plastic\nTop-loading design with double safety lock mechanism\nIntegrated water purge valve for safe maintenance\n\nPerformance & Compatibility\n\nOperation: Non-electric (Venturi effect or bypass)\nTablet compatibility: Trichlor and Bromine tablets only\nPressure safety valves included on Gigant models\nInstallation: Rigid PVC pipe required for optimal performance\n\nHow to Use It\n\nRead and follow the user manual before installation\nFill the feeder with slow-dissolving Trichlor or Bromine tablets\nUse control valves to regulate flow and tablet dissolution rate\nPerform weekly checks to refill tablets and ensure uninterrupted operation\nNever mix chlorine and bromine tablets in the same unit\nDuring winter, empty the feeder and store dry\n\nWhy Choose This Product?\nDossi feeders are built on decades of engineering experience and are trusted by over 25,000 installations worldwide.
