WITT-GASETECHNIK GMBH & CO KG

Non-Return Valves WITT non-return valves protect plants, pipelines and outlet points against reverse gas flow and meet all relevant standards and regulations. The product range of non-return valves includes a large choice of nominal sizes (up to DN200) and flow rates (0.35 – 106 SCFH). The sophisticated valve technology of WITT non-return valves provides small pressure drops making them also suitable for applications with smallest opening pressures. A high-quality sealing system with elastomeres prevents leakages, and dirt filters at the inlet point assure long service life of the non-return valves. Some non-return valve models can also be used as flashback arrestors. All non-return valves can be mounted in any orientation, are available with all connections, in brass and stainless steel and are suitable for almost all technical gases.

Powerful and service reduced Dome Pressure Regulator applicable for mounting in pipeworks.

Cordless handheld oxygen or combined oxygen and carbon dioxide analyser for checking modified atmospheres in food packs. The ideal instrument for portable, faster and accurate sample tests at the packaging machine, in stores or in laboratories. OXYBABY® is a cost effective mobile alternative to tabletop / fixed analysers for welding and food technology. It offers all benefits of modern technology quickly and easily by option. For example: Bluetooth for wireless communication and an integrated barcode reader. Ensure that the quality of packaged product is maintained (HACCP), and thus guarantee continued customer satisfaction. The ideal instrument for sample tests with a minimum sample gas requirement, allowing the smallest of modified atmosphere packages (MAP) to be tested. Information of internal pressure in the package via pressure indication.

Package Leak Detection system using a water-based bubble test. LEAK-MASTER® EASY allows the detection even of the smallest of leaks. After the package is placed into the chamber filled with water, the head space above the water level is evacuated using a venturi vacuum (compressed-air) system. This causes the package immersed in the water to inflate, allowing any leaks and their location to be identified by a stream of bubbles. Benefits: economical and uncomplicated visual inspection allows localisation of the leak for all flexible and rigid kinds of packaging (food-, pharmaceutical-, industrial- and other packaging) short testing period (< 30 sec.) easy-to-use intuitive operation – no special skills required easy installation and start-up no trace gas required in package can also be used for altitude simulation optionally also for vacuum packaging, set order-No. 956992700 no calibration required various chamber sizes avail

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.

Flashback Arrestors / Flame Arrestors WITT flashback arrestors / flame arrestors are used to protect single cylinders, outlet points or pipelines and can be used for almost all technical gases. Through the combination of established safety elements, flashback arrestors provide protection against flashbacks and backfire. Flashback arrestors also prevent the formation of dangerous gas mixtures within the pipeline. WITT flashback arrestors / flame arrestors meet all relevant standards (EN730-1/ISO5175), with the according tests from licensing offices such as the BAM (Federal Institute for Materials Research and Testing). A 100% product control assures highest quality. The flashback arrestors / flame arrestors are mountable in any orientation and are available with all connections and in brass or stainless steel. High-quality materials and filters in the gas inlet provide long service life of WITT flashback arrestors.

Non-Return Valves WITT non-return valves protect plants, pipelines and outlet points against reverse gas flow and meet all relevant standards and regulations. The product range of non-return valves includes a large choice of nominal sizes (up to DN200) and flow rates (0.35 – 106 SCFH). The sophisticated valve technology of WITT non-return valves provides small pressure drops making them also suitable for applications with smallest opening pressures. A high-quality sealing system with elastomeres prevents leakages, and dirt filters at the inlet point assure long service life of the non-return valves. Some non-return valve models can also be used as flashback arrestors. All non-return valves can be mounted in any orientation, are available with all connections, in brass and stainless steel and are suitable for almost all technical gases.

Safety Relief Valves / Blow-Off Valves WITT safety relief valves (blow-off valves) protect against overpressure by venting excess gases from pipelines, gas receivers and other equipment. The spring-loaded, direct-acting safety relief valves (blow-off valves) are suitable for individual opening pressures from 5 mbar to 45 bar (approx. 0.07 to 1 435 psi). The compact size allows easy installation in any orientation. A dust cap protects the safety relief valves (blow-off valves) against dirt. WITT safety relief valves (blow-off valves) are available in brass or stainless steel, as a ventable version, and with or without condensation outlet.

Gas Filters WITT gas filters allow the reliable filtration of the finest dirt particles in gases. Depending on the respective version, the gas filters can filter out particles from 3 to 40 micron and extend the service life of downstream equipment. The WITT gas filters provide high flow rates and multiple connections. WITT gas filters can be used for many technical gases. The gas filters – with or without condensation outlet – are designed for installation in pipelines or at outlet points. Gas filters can be changed while installed.

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.
