DB manifolds provide energy saving rates up to 25% compared to systems with flow-rate dynamic balancing.
These are the results achieved through the research carried out by the Department of Energy of the Politecnico of Turin (science director professor Stefano Corgnati): 12% of energy saving in a single residential unit / 14%÷25% of energy saving in a condominial boiler room with 8 residential units, based on the number of apartments with specific occupational profiles (system running 24/7, 7 hours of deactivation, 5 hours of deactivation).
DB manifolds keep the flow rate constant inside the single hydraulic circuits within a min-max differential pressure range, independently from the working conditions of the other circuits.
It features the following functions:
The bonnet is the key element of dynamic control.
When the pressure varies upon opening or closing some circuits, the controlled-deformation membrane of the bonnet cartridge is engaged and changes its port section according to the setting flow rate, also in case of high differential pressures.
DB manifolds are made with the main materials used in hydronic installations: brass, technopolymer and stainless steel.
Plus, they are available in the Low Flow or High Flow version based on the application need:
