Some with condensation outlet• For particles from 0.3–40 micron• Diverse applications – useful for many technical gases• High flow rates• Extend the service life of downstream equipment – by reliable filtration performance• Change of filter possible while installed • Large choice of connectionsGAS MIXERSHigh quality mixing systems for 2 or 3 gases particularly for allareas with sharply fluctuating mixed gas flows:• Easy operation• A proportional mixing valve or three single mixing valves provide infinitely variable mixture settings• Gas mixture withdrawal possible from zero to the maximumflow capacity• High process reliability• Independent of pressure fluctuations in the gas supply• Intermittent gas mixture withdrawal possible• Splash-proof and robust stainless steel housing• For flammable gases available as EEx-version with separate control cabinet • Integrated gas analysis for the control and documentation of the gas mixture production• Monitoring of the gas supply with alarmTEST EQUIPMENTFor the testing of all safety elements including flashback arres-tors and non-return valves. • Cost effective• Only one test rig for all tests– Leak tightness to atmosphere– Test of non-return valve against low and high back pressure– Function of pressure sensitive gas cut off valve– Measurement of flow capacity of safety device• Clear readings• Robust design• Maintenance free5
