Oxygen Changeover Panel, PSA to Manifold, switches over in under one second.

Why automatic PSA-to-manifold changeover matters

An on-site PSA oxygen plant reduces a hospital's dependency on cylinder logistics, but it is not a substitute for a backup supply. Compressors fail, adsorption beds need maintenance, and power interruptions happen. Where a bed-side oxygen line cannot tolerate downtime, the manifold cylinder bank remains the fallback — and the Oxygen Changeover Panel is what makes that fallback automatic rather than a matter of a technician reaching a valve in time.

The Neometrix Oxygen Changeover Panel, PSA to Manifold, for Gas Distribution is built around a simple operating principle: under normal conditions, oxygen from the PSA plant supplies the hospital bed line through a dedicated connection, while a manifold cylinder bank stays connected through its own separate line, on standby. If PSA supply pressure falls, the panel switches to the manifold bank automatically and pneumatically — without needing power, network connectivity, or an operator, resetting itself once the bank is refilled.

Working principle — automatic pneumatic switch-over

• Separate connection for the hospital bed line: The panel provides a dedicated outlet feeding the hospital bed-side pipeline, kept isolated from the manifold connection for clean fault isolation.
• Separate connection for the manifold: A second dedicated outlet connects the manifold cylinder bank, ready to take over the moment PSA supply is interrupted.
• Automatic change with manifold supply if PSA fails: The panel continuously senses PSA output. If it drops below the required pressure, the pipeline is transferred to the manifold bank automatically.
• Pneumatic switch-over: The changeover is accomplished pneumatically rather than through electrically-actuated logic alone, which keeps the transfer fast and independent of control-power availability.
• Automatic reset: The panel automatically resets itself for the next cycle once the depleted bank is replenished. No manual resetting is required, reducing dependency on staff availability at the moment of failure.

Technical specifications

Outstanding features & advantages, in detail

1. Continuous bed-side supply

Because switch-over is automatic and pneumatic, the hospital bed line does not depend on a technician noticing a pressure drop in time. The transfer happens as part of the panel's own mechanical operation.

2. Simple, isolated connections

Separate outlets for the hospital bed line and the manifold bank keep the piping arrangement easy to inspect, trace, and maintain — a factor biomedical engineering teams value during commissioning and periodic MGPS audits.

3. No manual resetting

Once the manifold cylinder bank is refilled, the panel resets itself automatically for the next changeover cycle, removing a step that would otherwise depend on ward or engineering staff remembering to reset the system.

4. Standard fittings, easy retrofit

A standard 1-inch BSP inlet connection allows the panel to be integrated into existing hospital pipeline infrastructure without custom fittings, simplifying retrofits at older facilities.

5. Overpressure protection

The integrated high-pressure regulator relief valve, set at 15.5 bar, protects downstream pipework and bed-side equipment during the changeover event and under normal operation.

6. Compliance-ready documentation

The panel is designed to comply with applicable national and international standards including MIL-STD, ISO, IS, and customer-specified requirements, supporting hospital procurement and MGPS compliance documentation.

System interface & connections

The Oxygen Changeover Panel interfaces with the following elements of a hospital or industrial gas distribution system:

• PSA oxygen plant (primary source): Feeds the panel under normal operating conditions, typically a NAMO series PSA plant with twin adsorption towers and PLC control panel.
• Manifold cylinder bank (backup source): Connected through a separate line, held in standby and automatically brought online if PSA supply fails.
• Hospital bed line: The dedicated downstream outlet supplying ward and ICU beds, isolated from the manifold connection.
• Pressure gauges & regulators: Monitor and regulate line pressure on both the PSA and manifold sides of the panel.
• High-pressure relief valve: Protects the pipeline from overpressure at 15.5 bar.
• 220 VAC control supply: Powers the panel's control and indication circuitry.

Applications across facility types

The Oxygen Changeover Panel, PSA to Manifold, for Gas Distribution is deployed across a range of healthcare and industrial gas distribution settings:

• Community health centres (CHC): Provides automatic backup for oxygen lines at sites where a manifold bank supplements a smaller PSA plant.
• District & general hospitals: Supports higher flow-rate requirements across multiple wards while maintaining a single automated changeover point.
• PM CARES-funded PSA plant sites: Interfaces with government-funded PSA oxygen plant installations to guarantee continuity of bed-side supply.
• Sub-district hospitals: Delivers a compact, low-maintenance changeover solution suited to smaller technical teams.
• Industrial & defence gas distribution: Applies the same automatic PSA-to-manifold changeover principle to industrial oxygen or process gas pipelines requiring uninterrupted supply.

Conclusion

The Neometrix Oxygen Changeover Panel, PSA to Manifold, for Gas Distribution closes the reliability gap between an on-site PSA oxygen plant and a manifold cylinder bank. With fully automatic pneumatic switch-over, self-resetting operation, and separate dedicated connections for the bed line and the manifold, it keeps hospital and industrial oxygen pipelines running without depending on manual intervention at the moment it matters most.
