Always Enough Breath - Gas Mixers for State of the Art Diving Technology
For example when welding pipes on the seabed, frequent dives are necessary. With a WITT gas mixer you can be sure you will never be out of air.
Gas mixtures of oxygen and helium (heliox) are used for the breathing gas supply. The diving gas heliox consists of 79% helium and 21% oxygen. The mixture is variable and depends on the necessary diving depth.
