A compact, modular semiautomatic changeover panel engineered to deliver uninterrupted highpurity gas supply by switching from a Primary to a Reserve cylinder/bundle when the primary source falls below a userset threshold. The operator selects the priority bank (left/right) manually; the panel performs pneumatic changeover automatically via differential pressure logic. Designed for tracelevel cleanliness, ultralow leak rates, and repeatable outlet pressure across a broad flow range.

Key Benefits

• Zerodowntime changeover with clear bank status indication

• Crossindustry compliance ready components and build options

• Scalable: singleline, dualline, and multigas manifolds; highflow variants

• Serviceable with modular valve/regulator cassettes

• Safetyfirst: integral relief, slamshut (option), line isolation, and purge

•  Typical Applications

• Automotive / Engine Emissions: zero/span calibration gases, burner air, lowppm NO/CO/HC blends, oxidizer/fuel switchover

• Pharmaceutical: process N, sterile air, CO for incubators/bioreactors, O for culture; cleanroom purges

• CVD/PVD & Diamond: UHP H, N, Ar, He, CH, BCl*, Cl

• Semiconductor (UHP):SiH* (with external safety), inert/oxidizer panels, analytical carrier gases, purge panels

• Aviation/MRO: O/N service carts, leakcheck benches, inerting

• Welding/Cutting: O, Acetylene*, LPG*, Ar/CO mixes; industrial series only

• Medical: O/NO/Air/CO distribution headers (regional standards options)

• Automotive Emissions: offer dualstage regulation for ultrastable span gases; add 0.5µm filter at outlet; incorporate bankempty contact to LIMS.

• Pharma: choose HPI with electropolished tubing and 316L wetted path; cradletopanel purge for bioreactor CO.

• CVD/PVD/Nano/Diamond: UHPS with VCR ends; specify compatible alloys (e.g., Hastelloy) for halides; N purge block and interlocked vent.

• Semiconductor UHP: UHPS with diaphragm valves, EP 10µin, 1×10 leak spec, particle & moisture certs.

• Aviation: oxygenservice brass or SS; shockmounted panel; MILstyle connectors for transmitters.

• Welding/Cutting: HFX with highflow regulators, slamshut, arrestors; oxygencleaning mandatory for O.

• Medical: dual header with automatic changeover; colorcoded bank ID; alarm contacts compatible with area alarm panels; use medical gas specific outlets and labels
