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.
1977: Gas mixer for modified atmosphere in the food industry
Pioneer work: WITT markets the first production gas mixers for vacuum packaging machines.
1978: Protection against reverse gas flow
Non-return valves enhance the gas safety equipment portfolio.

WITT develops special gas mixing systems for the filling and dispensing of beer.
1992: Mobile gas analyser OXYBABY
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.
1993: Hose coupler save money and improve safety
WITT hose couplers allow lightning-fast connection and disconnection of equipment. Of course according to EN561/ISO7289.
1993: MFCs for the glass industry
MFC technology (MFC = Mass Flow Controller) enables the precise gas mixing and metering, for example for gas burner systems in the glass industry.
1994: Helium leak testing
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.
1998: Who offers more? Pressure regulator with unrivaled flow rate
The new version of the manifold pressure regulator ADR 150 offers a flow rate of up to 150 m³ acetylene per hour.
2000: Biogas – make the most of waste
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.
2002: Hydrogen application protected up to 17 bar
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.
2003: Bright yellow and wonderfully aromatic – WITT lets bananas ripen
Mixing and metering solutions by WITT allow the controlled ripening of bananas by using ethylene. For perfect product quality at the point of sale.
2003: First package leak detection
The new LEAK-MASTER series enables the non-destructive leak testing of packages. Highly sensitive CO2 sensors detect even the smallest of leaks.

2005: Inline leak testing of food packages
The LEAK-MASTER MAPMAX as inline solution allows a 100% leak testing with up to 15 cycles per minute - unrivalled speed, even today.
2007: Gas analysis with zirconium sensor
The gas analyser PA delivers faster and more precise results by using a zirconium sensor.
2007: Wherever the gas mixture is required - with mobile gas mixers
The very compact gas mixer BM-2M proves to be the ideal solution for mobile use, e.g supplying small welding equipment.
