Description
Barberi Trolli and Trollino thermal solar groups are products which integrate all hydraulic components necessary for a forced circulation thermal solar installation: components for the installation, regulation and for the safety. The groups can be composed of the return line from panel and of the supply line to tank (Trolli) or only of the return line to the panel (Trollino). The same versions can have the controller for the thermal solar installation control (Trolli Plus).

The return line is composed of the pump, the mechanical flowmeter to read and regulate the flow, fill-in and flush of the system, ball valve with temperature gauge and integrated check valve, check disconnection device, safety group with pressure gauge, safety valve and expansion vessel connection. The supply line is composed of the ball valve with temperature gauge and integrated check valve, manual de-aerator.
