HV Distribution Headers

The distribution header is connected after the Hydraulic Header and is available with connections from single flow and return up to six individual flow and returns.  HV Distributor 60 range can be used for applications up to  2m3/h (50kW) and HV Distributor 70 range  up to 3m3/h (70kW).

Distribution header with insulation suitable for heat sources up to 70 kW (thermic rise ΔT=20°C in the primary circuit).

Maximum flow rate up to 3 m3/h – Max. 6 bar. Side connection 3/4”F for the expansion vessel and/or the drain valve.

Insulation box dimensions: 110 x 110mm.

Connections to the pump units: 1” Male, centre distance 125mm (pitch 250mm).

Connection to the hydraulic switcher cod. HW60/125-04 threaded end 1”1/4 Male (centre distance 125 mm), for the connection use n. 2 set cod. 04629SET (1”1/4).

Hydraulic Header HW 60/125

Hydraulic Header with insulation to be connected before the distribution header.  This device provides hydraulic separation of the primary circuit from the secondary circuit so giving a greater volumetric flow in the distribution header in comparison with the flow of the boiler. It is particularly suitable to be used in conjunction with condensing boilers.

In fact with a right setting of the boiler pump it ensures a low return water temperature (always lower than 57°C, that is the condensing temperature of the fluegas) so increasing the efficiency of the installation. Bottom connection 1/2”F for the boiler sensor.

Insulation box dimensions: 380mm x 110 x 110 mm.
