Witt’s gas mixer uses actuated valves

Witt Gas Controls has launched its state-of-the-art mixing system, the KM100-MEM+, which can mix up to three gasses.
This latest device uses electronically actuated valves, a further leap forward in the technology. It’s not only the gas mixture setting that is extremely precise in comparison to manual setting. The target values can also be reproduced exactly, even after changes in use.
The latest Witt development provides the option of remote control via processor technology and electronic motor-operated mixing valves. It can be driven via PC, PLC or a machine control system. All parameters can be conveniently called up, set, queried and documented.
The gas mixture can generally be set in increments of 0.1 percent and maintained with maximum accuracy. At its maximum 20 bar inlet pressure and 10 bar outlet pressure, the system generates a gas mixture output of up to 544 Nl/min (air equivalent). All technical gases (apart from toxic and corrosive gases) and combinations of combustion gas with air, O2 or N2O can be blended – including mixtures of up to three gases.
Witt has enclosed its product in a splash-proof stainless steel housing with compact dimensions of only 330 x 485 x 445 mm (HxWxD) and weighing a mere 22kg. The new mixer is available now.
