WITT Gas to Showcase Advanced Gas Mixing, Safety Solutions at FABTECH 2025

WITT Gas, a global provider in gas safety, control and analysis solutions, will showcase its latest innovations at Booth B33023 during FABTECH 2025. The exhibition runs from September 8–11, 2025, at McCormick Place in Chicago, IL. Attendees can explore WITT Gas’s advanced technologies for precise gas mixing, safety and reliability.

Featured products include the MEM+ gas mixer series and ULTRA valves, specifically the ULTRA non-return valves and ULTRAVENT safety relief valves.

MEM+ Gas Mixer Series

At the show, the MEM+ gas mixer series will be on display, which is engineered to deliver precise mixing of two or three nonflammable gases such as nitrogen, carbon dioxide or oxygen, serving a wide range of industrial applications. Electronically operated, motorized proportional valves enable adjustments in 0.1 percent increments, achieving the desired gas mixture in less than three seconds with accuracy better than ±1% absolute.

The MEM + series offers advanced connectivity through seven interface options, including Analog 4-20 mA, Ethernet, CanBus, OPC UA, Profinet, RS232 and Analog 0-10V, ensuring seamless integration into existing systems, the company reported.

"Users benefit from both remote operation via PC, PLC or machine controller and intuitive on-device operation through a touchscreen interface," said a company spokesperson. "Pressure equalization compensates for supply pressure fluctuations, supporting long-term stability and reliability. Continuous monitoring of inlet pressures and alarms for low-pressure situations add an extra layer of safety, while an integrated buffer tank manages fluctuating flow rates. The MEM+ series supports maximum inlet pressures of 20 bar and maximum outlet pressures of 10 bar, all housed in a splash-proof, brushed stainless steel enclosure for durability in demanding environments. "

ULTRA Valves

The ULTRA valve portfolio will also be showcased at the show. "The ULTRA nonreturn valves are designed for safety and reliability, protecting gas systems by preventing dangerous backflow. These valves feature extremely low opening pressures and exceptional tightness, making them ideal for sensitive gas installations. With minimal flow resistance and robust construction, they ensure safe and efficient operation even in challenging industrial settings," said a company spokesperson.

The newly introduced ULTRAVENT safety relief valves set a new benchmark for precision and dependability in pressure control, the spokesperson added. "This series is engineered for the precise regulation of both positive and negative pressure, controlling even the smallest pressure increases from as low as 5 mbar and delivering maximum safety in systems, containers, and production environments."

The ULTRAVENT 6, compact and direct-acting with a spring-loaded design, opens automatically when the set pressure is exceeded and closes again after pressure equalization. "As a mechanical solution, it offers advantages over more complex assemblies involving electronic components, resulting in a highly reliable and cost-effective option. The ULTRAVENT series is based on DIN EN ISO 4126-1, and valves are suitable for a wide range of applications including high-temperature environments, providing reproducible and accurate opening and closing performance in the millibar range," the spokesperson stated.
