Description
Integrated gas-air system with high power density based on DUNGS zero pressure multiple actuator MBC to EN 161 for modulating or multi-stage mode:
- Pneumatic integrated system comprising zero pressure mode and integrated signal gain possible
- Inlet pressure
- MBC-WND 65: pmax 6.5 kPa (65 mbar) (6.5 kPa)
- Modulation range up to 1:10
- Breaks up flow pattern and reduces resonances
- Offset correction of gas/air ratio at servo regulator
- Limits maximum flow by a low hysteresis flow restrictor, injector requires
- no replacement for different gas families
- Implemented by adapting system components and optimising to specific application and design requirements.
