With the model 36 WITT enhances the flashback arrestor for the first time with a pressure sensitive cut-off valve. This immediately cuts off the gas supply in case of a flashback and prevents dangerous further work.
The flashback arrestor Super 66 is born and offers a pressure relief valve, protecting the arrestor and hose. This WITT classic is available until today.
Brilliant add-on to the flashback arrestor: The integrated plastic body melts and the spring-loaded valve triggers and interrupts the gas supply before the device can heat dangerously. A dangerous backburning is stopped at its source.
Pioneer work: WITT markets the first production gas mixers for vacuum packaging machines.
Non-return valves enhance the gas safety equipment portfolio.
Pressure regulators using a gas cushion offer highest stability of the gas pressure even in the case of severe withdrawal or inlet pressure fluctuations.

The Super 78 combines all existing features of a flashback arrestor: flame arrestor, non-return valve, pressure and temperature sensitive cut-off valves and pressure relief valve.
In close cooperation with leading CO2 laser producers, the company develops special gas mixing components.
The 85-30 is up to now the biggest single WITT flashback arrestor. Approx. 20 cm long, 4.5 kg heavy and with up to 850 m3/h flow rate.
Safety relief valves to reliably protect tanks, pipelines and plants against overpressure.
WITT designs dedicated gas mixers for the filling of cylinders on a diving boat. Special mixtures of Oxygen and Helium are made depending upon the intended diving depth.
"Synthetic air" is a mixture of pure oxygen and nitrogen for medical applications. WITT synthetic air mixers offer easy operation via touchscreen, low investment and maintenance costs, easy integration into existing systems, and low energy usage.
Operating with thermal conductivity the MFA can analyse several gas mixtures – perfect for mobile service use.
WITT develops special gas mixing systems for the filling and dispensing of beer.
An era begins: the mobile one-hand-analyser by WITT is launched and makes the quality control of modified atmosphere packages easier. To this day the OXYBABY is the top-selling WITT analyser.
WITT hose couplers allow lightning-fast connection and disconnection of equipment. Of course according to EN561/ISO7289.
MFC technology (MFC = Mass Flow Controller) enables the precise gas mixing and metering, for example for gas burner systems in the glass industry.
WITT builds the technological heart of helium leak-testing devices, e.g. for testing of the integrity of fuel tanks in aircraft wings. For this ambitious challenge WITT combines gas mixers, gas metering, and analyser systems.
The new version of the manifold pressure regulator ADR 150 offers a flow rate of up to 150 m³ acetylene per hour.
Special WITT stainless steel non-return valves approved by the DVGW (German Technical and Scientific Association for Gas and Water) prevent the build-up of hazardous gas mixtures.
The stainless steel flashback arrestor F100N-ES offers protection against dangerous flashbacks for hydrogen applications and is suitable for working pressures up to 17 bar.
Mixing and metering solutions by WITT allow the controlled ripening of bananas by using ethylene. For perfect product quality at the point of sale.
The new LEAK-MASTER series enables the non-destructive leak testing of packages. Highly sensitive CO2 sensors detect even the smallest of leaks.

The LEAK-MASTER MAPMAX as inline solution allows a 100% leak testing with up to 15 cycles per minute - unrivalled speed, even today.
The gas analyser PA delivers faster and more precise results by using a zirconium sensor.
The very compact gas mixer BM-2M proves to be the ideal solution for mobile use, e.g supplying small welding equipment.
Electric mixing valves and electronic control units make the complete integration of gas mixers in complex processes possible, even with remote control.
The MAPY 4.0 WITT shows that design, ergonomics and functionality can be combined in a perfect way. The result: a Red Dot Award for outstanding product design.
WITT provides mixing and analyser systems for the precise dosing and supply of carbon dioxide in algae production processes.
The safety relief valve SV811 valve is approved for installation in passenger cars and buses. It protects the vehicles’ hydrogen system from dangerous overpressure in a broad spectrum of pressures from 2 to 45 bar.
More stable, more compact – after a re-design the WITT dome-loaded pressure regulators work with an integrated pilot pressure regulator.
The pressure regulating station 150NA for acetylene with automatic switch between connected gas sources and its intelligent process control ensures consistent gas supply and helps to reduce costs.
OXYSPOT determines the oxygen percentage in packages by using a light impulse. Fast and reliable.
