Rely on WITT for gas safety technology. HOW IMPORTANT IS SAFE GAS SUPPLY? ANDREAS HEYER: SENIOR PRODUCT MANAGER – WITT-GASETECHNIK

CENTRAL GAS SUPPLY SYSTEMS INCREASE SAFETY AND PRODUCTIVITY! Continuous gas supply, improved safety by less transportation of gas cylinders, more space at the point of use, flexibility and expandability – central gas supply systems offer numerous benefits. Field-proven solutions by WITT ensure the optimal realisation from gas inlet to outlet point, from conception to implementation. As market leader with longtime experience WITT offers all components for central gas supply systems – gas mixers, pressure regulator stations, flashback arrestors, outlet points, electronic control and special...

PRODUCT PORTFOLIO FLASHBACK ARRESTORS Protection of single cylinders, outlet points or pipelines against reverse gas flow and flashbacks: • Combination of all safety elements for optimal protection • Extinguish dangerous flashbacks or backfire • Avoid explosive mixtures in the gas supply • Wide product range for all kinds of applications • For all technical gases • Installation independent of the orientation • Long service life due to protection against dirt – via filter at gas inlet • All connections available • Available in brass or stainless steel PRESSURE REGULATORS Constant gas flow...

QUICK COUPLINGS Safe and quick connection of equipment: • Lightning fast connection and disconnection of equipment • Gas-tightness when disconnected • No build-up of explosive gas-mixtures in the pipe line – because of non-return valve • No confusion between connections – because of different probes for Oxygen, Fuel and Inert Gases • Simplest selection of the right body and probe – because of new colour coded probe • All connections available • Dirt-filter protects hose coupling and equipment Reliable filtration of the finest dirt particles in gases: • For pipelines and gas outlet points....
