What is a Solar Pumping Station?
A solar Pumping station is a module containing Heat transfer fluid circulation pump, solar differential controller, check valve, safety valve, filling valve, Tank temperature sensors and collector temperature sensor.
This solar pump station is a pre-installed and leak-tested for transferring heat from the collector to the storage tank. It contains important fittings and safety devices for the operation of the solar thermal system:
- Ball valves in flow and return in combination with check valves to prevent gravity circulation.
- Flow meter for displaying the flow rate
- Manometer for displaying the system pressure
- Safety valve to prevent inadmissible over pressure
- Flushing and filling unit (optional) for flushing, filling and emptying the solar thermal system.
