Sinus HydroFixx, the manifold with an integrated hydraulic separator, has a compact design Sinus MultiFlow Domestic perfectly adapted for the restricted space available in modern central heating units. This manifold performs hydraulic decoupling and ensures optimum hydraulic conditions in the entire heating system. In addition, efficient utilisation of the individual temperatures can be achieved by arranging various heat sources and heat consumers accordingly. The Sinus HydroFixx technology ensures that the entire system functions properly up to a flow rate of 90 m³/h. Sinus HydroFixx
