Pool chlorine and bromine compact dispenser

Detailed Description

Dossi tablet feeders represent the trusted standard in automated pool sanitation. Built in Italy with precision and high-quality materials, each feeder is engineered to deliver consistent, measured dosing of chlorine or bromine tablets directly into your pool circulation system. From small backyard pools to large-scale wellness centers, Dossi feeders offer models and capacities to suit every need.

The feeders operate through a non-electric system that uses either the Venturi effect or bypass connection, ensuring compatibility with most existing filtration systems. This automatic dosing method keeps the sanitizer level optimal, reduces the need for frequent manual dosing, and enhances user safety by limiting direct contact with chemicals.

Detailed Features

• Durability: Made with ABS plastic resistant to chlorine and bromine corrosion.
• Operation: Fully non-electric, using water flow dynamics to dose chemicals.
• Tablet compatibility: Only for trichlor or bromine tablets, ensuring consistent performance.
• Installation: Models available for both in-line and off-line setups.
• Safety: Anti-return valves and pressure relief features, especially in larger models like the Dossi Gigant.
• Sizes: From 3.5 kg to over 20 kg tablet capacity, suitable for different pool volumes.
• Maintenance: Minimal – weekly checks are generally sufficient for peak performance.

Comprehensive Description

With over a decade of engineering evolution, Dossi feeders combine modern pool care science with practical, easy-to-install designs. They fit seamlessly into new or existing plumbing lines and support both residential and professional environments. The dosing is uniform and can be finely adjusted using the integrated regulator, giving you full control over sanitization intensity without fluctuation.
