WITT-Gasetechnik has created a complete pressure regulating station for acetylene with a 150m³/h (approx. 5295 SCFH) flow rate in the form of the new 150NA.
“The 150NA offers a high degree of safety with operating convenience and is especially suitable for applications with large acetylene consumption and high requirements regarding a fail-safe gas supply”, Product Manager Andreas Heyer sums up the advantages of the new WITT pressure regulating station. The highlight of the system is a switchover device that changes fully automatically between two connected gas sources, as required. “Pressure transmitters monitor the filling level of the connected cylinder batteries or trailers”, declares Andreas Heyer. “If a gas cylinder empties, the system switches to the full one without interruption.”
The automatic opening and closure during the switchover occurs smoothly via motor-powered stopcock instead of simple solenoid valves. This ensures a constant working pressure and spares the downstream pressure controller. The system shuts down automatically in the event of a fault. On request, the pressure control station can continue to be used in manual operation, thereby maintaining the gas supply. The 150NA keeps the outlet pressure “extremely stable” for the working process, even during intense fluctuations in the inlet pressure and flow rate.
