GAS MIXER KM 10-2 FLEX Gas mixing systems for 2 defined gases, designed for variable processes with a mixing range from 5-92%. See other ranges on overleaf. Specially designed for applications with only low gas consumption. Ideally suitable as a portable desktop unit, e.g. for laboratory applications. Using a new mixing technology, no receiver is required. Capacity range up to approx. 28 Nl/min. For the exact pressure and flow capacity ratios, please see the technical data. Benefits ●● high mixing accuracy ●● avoids the need to stock multiple pre-mixes (cost saving) ●● does not require receiver (cost and space saving) ●● inlet gas filters protect the device against impurities ●● pneumatic operating principle, no electrical connections required ●● mixed gas production from 1 l/min to the max. flow ●● robust, compact design ●● minimal maintenance required Easy operation ●● a mixing valve with a control knob and %-scale provides infinitely variable mixture settings High process reliability ●● independent of pressure fluctuations in the gas supply ●● independent of withdrawal fluctuations (in permitted range) ●● fail safe design (unit shuts down on failure of either gas supply) ●● lockable to prevent tampering Options ●● alarm module NXT+: integrated inlet pressure monitoring with digital display for pressure (with analog pressure transmitters) plus optical alarm, adjustable alarm limits, obligation of acknowledgement, protection of alarms, interfaces for controlling external alarms etc. Other models, options and accessories available upon request. Please identify the individual gases at the time of enquiring!
