Principle of operation of a heat distributor-manifold with low loss header
Flow and pressure disturbances may occur in systems with a boiler circuit pump and, in addition, pumps for individual heating circuits. The manifold creates a low pressure drop zone in which the primary and secondary circuits are hydraulically separated. The flow in one of the circuits becomes independent of and no longer influences the flow in the other circuit. As a result, both circuits achieve the desired flow, which is generated by the pumps used, without excessive distortions.
The manifold consists of a separator - big steel low loss header (primary circuit) and a compact manifold (secondary circuit) directly connected to the separator. After the supply (primary circuit) has been installed, the supply for the secondary circuits must be connected to the same manifold chamber. Crossover between supply and return should be strictly avoided .
The installation position of low loss headers 2+2 is free, horizontal or vertical, but horizontal connection is recommended as the vertical position makes it impossible to use air vents.
The ½ ”connections (2 pcs. near the main exits) are intended only and exclusively for the vent and drain valves. The heating circuits should definitely not be connected there.
CORRECT INSTALATION CAN ONLY BE DONE BY A QUALIFIED INSTALLER
