Pool chlorine and bromine dispenser - In-line and off-line

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

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.
