Gas mixing systems - 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.

The ExoFlex™ line of exothermic gas generators is designed to generate lean or rich exothermic gas. The generator includes automatic output turndown to 20% of the generator capacity with little loss of efficiency using the patented, maintenance-free ExoInjector™ gas mixing system. Thanks to a patented fuel injection technology that utilizes electronic flow measurement and precise ratio control, ExoFlex™ consistently provides the ideal mixture for high quality gas production. Another innovative design feature is the trim control input with programmable control range for precise generator control, which also eliminates the need for extra meters or valves. The ExoInjector™ easily replaces existing carburetor/pump designs for a significant reduction in process costs.

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.

WITT offers high-quality gas mixers / gas blenders and gas metering systems for two or more gases, for high flow rates and highly fluctuating gas withdrawals. You can choose between various options: According to your requirements, WITT gas mixers / gas blenders are available for nearly all technical gases and flow rates: for the optimal gas mixture for welding applications, the required gas concentration for food packages (modified atmosphere packaging = MAP) or the production of synthetic air for medical applications. State-of the art mechanical or electronic gas mixing systems provide accuracy and process safety. You can also control your gas mixing systems conveniently via Intranet, Internet or mobile devices. Combinations of WITT gas mixers / gas blenders with other WITT quality products such as gas analysers are also possible. They can be manufactured as complete system solutions.

The use of protective gases is an essential element of precise quality control (HACCP) in food packages (Modified Atmosphere Packaging = MAP). MAP gas mixers by WITT provide controlled gas quality and safety in your packaging process – for germfree and preserving food. WITT offers gas mixing and metering systems for all packaging machines used in the food industry, no matter if vacuum packaging, thermo forming, flow pack or chamber packaging machine. The gas mixing systems are adjusted to your specific product type and processing and require only basic installation requirements. WITT system solutions are developed in close collaboration with national food and research institutes. WITT is approved and certified according to ISO 22000 for food safety.
