If the stations lose pressure when many handles are open, or the mains delivers under 2 bar, a pre-pressure Booster solves it. We can measure your supply.
Pre-pressure
Boosters.
Raises the inlet pressure when the mains cannot supply the stations. 120 to 1080 L/min at 3 to 5 bar.
Five sizes. Before everything else.
Sized by how much water the stations behind it draw. All models are F.

Where it sits
Before the stations. Not instead of them.
The pre-pressure Booster sits between the mains and your Main Stations or 27 bar Booster.
A weak supply
When the mains cannot keep up, stations lose pressure as more handles open.
A steady inlet
It raises the inlet to 3 to 5 bar, so the system behind it never runs short.
Full pressure at every handle
The Booster or Main Station delivers its full pressure, even with every handle open.
Match the flow of the system behind it. A B 400-27 needs at least 400 L/min, so a B 630-3 F covers it with room to grow.
It raises pressure from the mains. If the local rules require a break tank, the pre-pressure Booster draws from it.
It is built for smaller systems where Main Stations run straight off the supply and need a higher inlet.
