Gas mixers with electrical mixing valves from the MEM+ Gas Mixers Series are suitable for practically all popular gases and a large number of applications. Proportional or individual mixing valves – depending on whether 2 or 3 are mixed – form the core of this mixing process, similar to the mechanical mixing process. The functioning of the mixing valves is ingeniously simple: a moving piston in conjunction with different orifices controls the flow rate of the gases, thereby producing the desired mixture in less than 3 seconds. The technical genius lies in the high-quality materials and precise production of the individual components, coupled with correct calculation of the relevant piston-orifice combination.
In contrast to mixers with mechanical mixing valve, the electrical mixing valves are not operated manually via a rotary knob but instead via small electric motors. The electric motors are operated via an electronic controller. Benefits: First and foremost, the mixers can be regulated more finely electrically than by hand, thus resulting in a more exact gas mixture. The electronic control also allows easy reproducibility of gas mixtures. With remote operation, the mixing systems can be integrated in a network, where they can be controlled and monitored conveniently from a central point. And not to be overlooked is the constant pressure regulation by dome-loaded pressure regulators integrated into gas mixers with electrical mixing valves. The gas mixers are suitable for continuous extraction or also discontinuous extraction (using a gas tank), depending on the application.
