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. What is the Dossi Automatic Tablet Feeder? The 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. Detailed Information: Key Benefits Automated sanitation: Reliable chemical dosing for chlorine or bromine tablets Energy-free operation: Works using water pressure or bypass flow—no electricity required Versatile installation: Choose between in-line (Venturi) or off-line (bypass) setups Extended autonomy: Larger models require fewer refills, perfect for busy owners or staff Safe and sealed: Locking lids, anti-return valves, and purge systems built in Compatible with controllers: Integrates with AstralPool Poolwatch and Easywatch systems Main Functions Dossi 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.
