The DEFRO distributor is used to evenly divide the water flow in the central heating system. between two or three pump groups. Quick and easy connection of pump groups to the distributor set facilitates the installation of the boiler room installation and allows you to eliminate unnecessary substitutes. DEFRO’s offer includes manifolds supporting 2, 3 or 4 sections of the heating circuit.

The distributor connections have threaded connections, prepared for quick connection of the distributor to the boiler circuit and pump group. The offer of distributors is divided into models, in which we distinguish a typical DR distributor and DSR distributors with a built-in hydraulic clutch used to balance the free flow and pressure of the liquid. The whole thing is encased in EPP insulating foam to prevent the liquid from cooling down, and the included wall brackets make installation easier. In addition, the manifolds have connectors for mounting a drain valve or an immersion sleeve to the temperature sensor. The guarantee of quality is the fact that all manifolds are subjected to factory leakage tests.

The manufacturer provides a 36-month warranty from the date of purchase when installed in accordance with the installation and use instructions.
