About WITT-Gasetechnik
WITT-Gasetechnik is a manufacturer of gas safety and gas control technology with over 80 years of experience. The company began with the introduction of the dry check valve (flashback arrestor) for the safe handling of flammable gases in cutting and welding. Today's product portfolio includes gas mixers (mechanical, electronic and with mass flow controllers) for all common technical gases such as argon, nitrogen, carbon dioxide, helium, hydrogen and oxygen, stationary and portable gas analysers, leak testing devices for packaging, flashback arrestors, gas check valves, safety valves, gas pressure regulators, gas filters as well as hose and quick couplings. Components made of brass, stainless steel and aluminium are used, among others, in food & beverage, the steel industry, automotive engineering, aerospace and engine manufacturing, and in thermal processing. WITT supports customers beyond product selection and planning through commissioning, maintenance and repair, offering worldwide service from a single source. Production is certified according to ISO 9001, ATEX, PED, ISO 13485 and ISO 22000.
