Delivery and return circulation group for primary circuits of solar systems
The flow goes from the solar panel to the boiler
It includes:
Interception ball valves with thermometers,
Pump for solar plants, air vent group, 6 bar safety valve
Filling and drain taps to wash the system before filling
0-12 lt/min flowmeter to regulate the flow
Antigravity check valve, gauge, thermalproof shell
Function
The solar modules are
employed in the primary
circuits of solar systems to
manage the thermodynamic
cycle of the heat-transfer fluid
between the solar panels and
the hot water storage tank.
The S004 module is also
equipped with electronic
controller which, through a
sophisticated monitoring system and safety functions, ensures the total protection of the system during its operation.
