The SpiroVent Superior S250 is designed for small to medium-sized commercial and residential installations - or in other words, smaller volume installations. This model expands the range of deaerators we offer. This allows us to meet the growing demand for new plants that operate at lower temperatures.

Word is spreading that our vacuum degassing technology is quieter than ever before. The key to this lies in our patented Venturi loop, a variable-speed centrifugal pump combined with a Venturi nozzle.

A sensor continuously monitors the boiler pressure during the degassing process. The pump is adjusted accordingly. This ensures smooth operating pressure stages and precise pressure control.

In practice, this means very low resonance and barely perceptible operating noise, with a sound level of just 41dB(A)!

Since all the air is removed from the system, it can no longer cause any disturbing noise.
