Medical Gas Manifold

Designed for automatic switching between two gas sources.
Automatic switching can be achieved without operator debugging.
Can continue normal work when the electrical system is powered off.
Complies with NFPA 99 of the United States, HTM 02-01 and 7396 of the UK.
Separation of strong and weak electricity, with 220V inside the power supply box and 24V weak electricity for the manifold.
Pilot-controlled switching of gas circuits helps ensure stable pressure.
Two-stage pressure-stabilizing regulators provide one regulator in use and one backup.
Temperature monitoring helps prevent frosting, overheating and gas leakage.
PLC control provides precise pressure and stable control, 485 remote monitoring output and audible/visual alarm testing.
Optional automatic switching and linkage between the main liquid oxygen gas circuit and the manifold.
