Gas mixing - Import export

The RCV Plus™ Gas Mixing System is a combination of flow meters specifically designed to monitor and control the ratio of two gases. It consists of an RCV Plus™ and a FLO-TRONIC Plus™. The RCV Plus™ utilizes a micro-processor that continuously compares a preset ratio to the real-time ratio of the two gas flows, as measured by the FLO-TRONIC Plus™, and the ratio control valve itself. Using a stepper motor, the RCV Plus™ continuously adjusts the flow metering needle-valve to precisely maintain the preset gas ratio. The real-time ratio is continuously displayed on the LCD screen of the RCV Plus™. Included in the RCV Plus™ is an optional input for the addition of a trim gas, which is frequently used for process control. Trim gas addition is additive to the ratio. When trim gas is used, the continuously displayed real-time ratio then includes the trim gas addition.

Despite the increasing level of digitalization, an ever-increasing demand for paper and pulp products can be observed. However, a shift is taking place from print paper qualities to packaging paper and cardboard. The wide range of paper products requires a variety of production processes. These include mechanical and chemical processes which, depending on the form and variant, produce different pulp qualities. Stirring and mixing are essential unit processes in all types of paper and pulp production. Mixing tasks range from liquid/liquid or gas/solid/liquid mixtures, through mixing of complex liquids, and include mixing of chemically reactive components. Improving and optimizing mixing processes in the paper and pulp industry can lead to end product improvements; such as increased strength, improved luster, or significant energy or chemical savings.

The EGR Cooler, developed in close collaboration with our customers for medium and low speed engines, ensures that the recirculation exhaust-gas is mixed at the lowest possible temperature with the air for the combustion process. EGR Coolers are an essential element of EGR systems for the next engine generation which already now fulfills future emission guidelines according to IMO (International Maritime Organization), EPA (US Emission Protection Agency), EURO, etc. We have developed various cooler designs with regard to the different requirements of EGR Coolers at 2-stroke and 4-stroke engines. The patented design for 4-stroke engines high pressure EGR system enables cooling of exhaust gas, some of which are over 700 °C, down to 50 °C.

The Mixor™ is a precision compressor-carburetor device which accurately mixes gas and air in any selected ratio, and compresses it for use with endothermic cracking, or exothermic cracking generators, or as a source of pre-mixed gas and air for torch brazing, flame heat treating, or sort metal melting.

The EndoInjector™ is a precise gas mixing / control system for endothermic gas generators. It incorporates a patented fuel injection design that utilizes electronic flow measurement and precise ratio control to consistently provide the ideal gas mixture for high quality endo gas generation. The fuel injection design automatically delivers gas mixture on demand, providing only as much endothermic gas as furnaces require to reduce operating costs and eliminate gas waste. EndoInjector™ typically pays for itself in less than 1 year. The ExoInjector™ is designed specifically for exothermic gas generators. While similar in concept, the ExoInjector™ differs from the EndoInjector™ in that it comes in modified mechanical versions to accommodate pre-mix or nozzle-mix burners with a custom HMI software that allows for predefined ratio set points for burner ignition, rich exo, and lean exothermic gas. The system can be modified to provide hydrogen content control and water vapor monitoring.

This compact micro torch is ideally suited for melting the ends of sample tubes precisely and safely. As a very small flame can be adjusted, it is possible to melt the capillary precisely at a defined point without excessively heating the remaining capillary, as is the case with standard torches. The torch is operated with a hydrogen/oxygen or a propane/oxygen mixture, both of which provide a very hot flame that even permits quartz glass to be processed. This torch is an extremely versatile tool with which practically all types of glass can be processed – from simple flaming to highly complex tasks. Features of the micro torch Fine, concentrated needle-point flame High heating capacity Mixed-gas operation Two separate needle valves Complete with fine nozzles Torch length >130 mm (without nozzle) Operating principle The torch consists of a gas mixing chamber and two gas inlets, which are also suitable for aggressive media such as hydrogen and oxygen. Two needle valves at the...

The NDIR bundle N2O is made up of optimally matched thin film infrared emitters and a corresponding IR thermopile detector to measure nitrous oxide in gas mixes. The kit has a short delivery time and therefore achieves measurement results in a short time. This is especially an advantage for developers in research projects with a limited time span. The two-channel detector's optical filter has been optimized for the absorption spectrum of N2O (CWL: 4525 ± 20 nm / HBW: 83 ± 6 nm) and can provide important data, especially in the analysis of exhaust gases in the automotive, railway and marine sectors, the monitoring of industrial exhaust emissions and environmental monitoring.

The surface of the perforated metal plank, type BN-GA is a mix of closed punched nobs facing upwards and conical drain holes facing downwards. This means that the grating does not have any sharp edges on top and can be walked on easily even without footwear. At the same time, however, any liquids can be quickly drained through the conical drain holes so that no hydroplaning can occur.
