The Pro range consists of 2 permanently installed refill products for commercial systems of different sizes. They can be used to fill the system and to refill water losses from the system (top up/refill). They have an LED conductivity indicator and a Fill Combi (backflow preventer, pressure reducer and pressure gauge) as standard. There are two sizes (9.5 and 23.0 liter bottle) for the SpiroPure Pro (fixed filling).
