Description
The VULKAN Modula AM 45/300 K Effect is designed for central gas supply installations that have already outgrown compact changeover stations. The system uses 2 manifold fin regulators HR 20 Effect, 1 automatic changeover block, 1 main shut-off valve and optional contact gauges according to DIN EN 837-1, mounted on a stainless steel base plate. Catalog data specify 300 bar inlet pressure, 20 bar outlet pressure and up to 170 Nm³/h flow.
Unlike semi-automatic systems, which still leave part of the switching cycle dependent on operator action, the Modula automatic manifold platform is designed to switch from the depleted side to the full side automatically. That reduces intervention points, lowers the risk of timing errors during cylinder replacement and supports more stable process continuity in real production.
The real commercial value of AM 45/300 K is not just capacity. It is the combination of higher throughput and autonomous changeover for welding plants, metallurgical users, laser systems and larger process gas headers. If manual or semi-automatic systems belong to the era of routine operator intervention, this product belongs to the era of process continuity.
Key Advantages
- Up to 170 Nm³/h flow supports larger central gas supply duties.
- Automatic changeover reduces the operational weakness of semi-automatic reset logic.
- HR 20 Effect regulator architecture strengthens performance positioning.
- Modular platform can be expanded to site-specific requirements.
- Optional DIN EN 837-1 contact gauges improve visibility at the manifold.
Food-Gas / Compliance Positioning
This manifold can be positioned for food-gas projects when it is ordered with the appropriate wetted materials, elastomers, cleanliness level and documentation package. Regulation (EC) No 1935/2004 defines the basic requirement that materials in contact with food must not transfer substances in quantities that could endanger health or unacceptably change the composition or organoleptic properties of food. Regulation (EC) No 2023/2006 adds GMP requirements for controlled manufacturing processes. In Germany, LFGB is part of the legal framework used for control of food-contact materials and articles.
