About this product
The station is a premounted group of valves and fittings checked for leakage and used to
transfer the heat from the primary (solar circuit) to the secondary circuit (heating circuit or
domestic hot water circuit).
It contains a preset controller as well as important fittings for the operation of the system:
Ball valves in the primary circuit (flow and return)
Piston valves in the secondary circuit (flow and return)
Check valves to avoid involuntary gravity circulation in the flow and return of the solar
circuit, non return valve in the return of the secondary circuit
Pressure relief valves to prevent inadmissible overpressures in the station
Pressure gauge for displaying the installation pressure in the primary circuit
Vent valves to easily vent the primary circuit and the secondary circuit
Fill and drain valves with caps to flush, fill and drain the primary circuit
A flow meter (FlowRotor) and temperature sensors for heat quantity balancing (primary)
In the heating circuit, the installation must be equipped with a safety group, that can be ordered
separately.
The expansion tank required for operation must be adapted to the size and the requirements of
the installation and must be ordered separately.
The cap-type valve (DN 20: item no. 5302, DN 25: item no. 5301), which is also separately
available, allows the expansion tank to be easily mounted and separated from the solar thermal
system.
The wrapping materials are made of recyclable materials and can be disposed of with
recyclable materials.
