Central Gas System High-Pressure Manifold with Regulator

Information

In enterprises where the central system is installed and available, the pressure of the gas coming from the source (fixed or mobile, tube pallets, cylinders or special containers) is reduced to the pressure level required by the central system with the high-pressure manifold with a regulator.

Features:

• It offers high compressed gas (Inert Gases) up to 600 Nm³ / h and up to 230 bar inlet pressure.
• A maximum inlet pressure of 230 bar is reduced to outlet levels of 10 bar, 20 bar, or 40 bar.
• Equipped with 2 cylinder connections with valves, suitable for use with individual cylinders or cylinder bundles.
• Extension connections on both inlet sides allow additional cylinders or bundles to be connected to the system by purchasing extra cylinder valve connections.
• These are central systems equipped with two pressure regulators, two solenoid valves, pressure transmitters, and a control unit with alarm functions.
• The pressure values supplied to the left and right manifolds can be digitally monitored via the control unit.
• Thanks to the colored cylinder indicators on the control unit, the cylinder fill levels and which side is active can be monitored remotely.
• The system continuously monitors the cylinder pressure level; when the pressure drops to a critical point, the alarm alerts the user and automatically activates the other line, ensuring uninterrupted and safe gas flow.
• All components of the system are mounted on a high-strength stainless steel sheet.
• In oxygen systems, a flashback arrestor is installed before the ball valve on the outlet line.
• Check valves located at both cylinder connection valves prevent gas backflow, thereby enhancing system safety.
• Thanks to its compact design, it occupies minimal space.
• The safety relief devices located in the pressure regulators ensure safe venting of excess pressure in case of malfunction.
