Medical Gas Pipeline Systems (MGPS) for Hospitals | ACCO
The Medical Gas Pipeline System (MGPS) delivers life-critical gases — oxygen, nitrous oxide, medical air, medical vacuum — from central sources to every OT, ICU, ward, and outlet in the hospital. A well-designed medical gas pipeline system is invisible when it works and catastrophic when it fails. This guide covers MGPS design, standards, installation, testing, and commissioning for hospitals in Pakistan.
Ahmed Construction Company (ACCO) designs and installs MGPS per HTM 02-01, ISO 7396, and NFPA 99 standards across all our hospital projects.

🧪 What Gases Does MGPS Deliver?
- Medical Oxygen (O2): All patient beds, OT, ICU, resuscitation.
- Nitrous Oxide (N2O): OT, dental, labour.
- Medical Air: NICU, ICU, ventilators.
- Medical Vacuum: OT, ICU, ward suction.
- Anaesthetic Gas Scavenging (AGSS): OT.
- Carbon Dioxide (CO2): Laparoscopic OT, IVF.
- Nitrogen (N2): Orthopaedic OT (power tools).
- Instrument Air / 7-bar Air: Surgical tools.

🏭 MGPS Source Options
- Cylinder Manifolds: Small hospitals; primary/secondary/reserve bank.
- Liquid Oxygen (VIE): Mid to large hospitals; tank + vaporiser.
- Oxygen Concentrator (PSA): Large hospitals; on-site generation.
- Medical Air Compressor Plant: Duplex or triplex oil-free compressors + dryer + filter.
- Medical Vacuum Plant: Duplex/triplex vacuum pumps with receiver tank + bacterial filter.

⚖️ Cylinder Manifold vs Liquid Oxygen (VIE) — Comparison
| Parameter | Cylinder Manifold | Liquid Oxygen (VIE) |
|---|---|---|
| Best For | < 100 beds | > 100 beds |
| Storage Capacity | Limited | Very high (3–10 tonnes) |
| Refill Frequency | Weekly to daily | Weekly to monthly |
| Operating Cost | Higher per m³ | Lower per m³ |
| Installation Complexity | Low | High (concrete pad, safety zone) |
| Backup | Reserve cylinder bank | Cylinder bank required |
