WITT Pressure regulating station with full automatic changeover for central gas supplies.
Every pressure regulating station 100% tested.

Benefits:

• powerful manifold pressure regulating station 150NA to regulate high flows up to 150 m3/h
• extremely stable outlet pressure, independent of inlet pressure and flow rate
• fully automatic changeover between 2 gas sources (bundles or trailers)
• electronic WITT-SWITCH-TRONIC with graphical filling level indicator
• intelligent software and extremely low pressure drop (Δp) provide optimal draining of the manifold or bundles
• electronic pressure transmitter for filling level control
• warning if bundle/trailer is empty
• connections for external devices
• motor-controlled ball valves (230 V) for smooth changeover without pressure peaks
• emergency shutdown
• manual emergency mode possible
