Calculate the load first
Load is calculated from outlet count per department, expected usage rates and a simultaneous-use factor. Intensive care, theatres and emergency drive the highest demand; wards are less continuous.
Plan for peak rather than average demand, and add headroom for expansion if the facility intends to add beds.
System components
| Component | Role |
|---|---|
| Generation plant | On-site oxygen production |
| Manifolds | Cylinder-based back-up source |
| Compressors and vacuum | Medical air and central suction |
| Pipeline | Delivery to points of use |
| Outlets | Connection point at the bed |
| Alarms and monitoring | Warning on low pressure or fault |
Back-up is not optional
Any system needs a second source that takes over when the primary source stops, whether for maintenance or a fault. This is usually a cylinder bank with an automatic changeover manifold, sized for a reasonable run time until the primary source is restored.
Testing and maintenance
- Pressure and tightness testing before commissioning
- Gas purity verification at the outlets
- Testing alarms and changeover points
- Scheduled service of plant, filters and dryers
ALQASER's oxygen project experience
ALQASER's scope covers PSA generation plants, manifolds, compressors and vacuum systems, copper pipelines and outlets, alarm and monitoring and purity testing, with capacity study, installation and pressure testing. Company records also include historical medical oxygen project experience, among them work associated with Ajdabiya and Ibn Sina — cited as historical experience, not current contracts.
