Model note

What the Blumenberg Nachfüllautomatik is

The Nachfüllautomatik keeps a Blumenberg plunge pool topped up with fresh water. Each dip displaces about 10 litres over the overflow; the sensor sees the level drop and the valve refills, then keeps running for a set time so that a fixed amount of fresh water reaches the pool per bather.

It is standard-ready on the pools with a plastic inner tub; on solid tubs without an insert the NF Rohrset adds the double overflow and sensor riser it needs.

Close alternatives we also supply and install: the Blumenberg teilbare Ausführung (Tub made in two halves), the Blumenberg Innentrittstufe / Brettsitz (One step standard, more on request), the Blumenberg Oberflächen-Varianten (Decor wax, flamed, pool blue). The Blumenberg overview lists every range.
