Oxygen Changeover Panel, PSA to Manifold: A Single Point of Failure the Ward Cannot Afford

A hospital that makes its own oxygen with a PSA plant still needs a backup, usually a manifold cylinder bank. It also needs a way to move between the two without a technician walking to a valve while patients wait. The Neometrix Oxygen Changeover Panel does that automatically: it transfers the pipeline between the PSA plant and the manifold bank, so the bed-side line does not go dry whichever source is active.

Two Sources, One Uninterrupted Line

The panel sits between the PSA plant, the manifold cylinder bank and the hospital pipeline, and it works in six steps:

1. The PSA plant is the primary source and feeds the bed line through a dedicated connection.
2. The manifold bank sits on standby through its own separate line.
3. The panel continuously senses the supply pressure.
4. If PSA output falls below the required threshold, the panel switches to the manifold supply pneumatically, with no electrical logic delay and no operator action.
5. A high-pressure regulator relief valve set at 15.5 bar protects downstream equipment during changeover.
6. Once the depleted cylinder bank is replenished, the panel resets itself for the next cycle.

Key Numbers

– Oxygen flow rate: 160 to 1500 LPM at 4.2 bar
– Inlet connection: 1 in BSP
– Relief valve: 15.5 bar
– Control supply: 220 VAC
– Transfer: automatic and pneumatic, under one second

Designed for the Pipeline It Serves

Separate outlets are provided for the hospital bed line and the manifold bank, which keeps ward connections simple and traceable. The range of flow rates suits community health centres up to larger district hospitals, and the standard 1 in BSP inlet makes it straightforward to integrate with existing medical gas pipeline infrastructure. The product page describes the panel as the interface component used across district hospitals, community health centres and PM CARES-funded PSA plant installations.

Frequently Asked Questions

Why does a PSA plant still need a manifold backup?
Because any on-site plant can fail, be taken out for maintenance or fall below the required pressure. A manifold cylinder bank gives the pipeline a second, independent source. The changeover panel is what makes that backup useful in practice, by switching to it automatically at the moment the PSA output drops instead of waiting for someone to notice.

Why is the switch-over pneumatic rather than electronic?
Because it removes a dependency. A pneumatic changeover does not rely on electrical control logic or operator response, and it completes in under one second. The panel does have a 220 VAC control supply, but the transfer itself is accomplished pneumatically and the panel resets itself once the depleted bank is refilled.
