Oxygen for hospitals
Novamed Vietnam’s hospital oxygen solution is the C-System PSA oxygen generation system installed inside provincial and central hospitals, producing medical oxygen at 93 ± 3 % from ambient air to TCVN 7742:2007, in place of liquid oxygen and cylinders.
Updated
Static view: tower A is adsorbing, tower B is venting. The towers alternate.
- The compressor feeds clean air (about 21 % oxygen) into the system.
- Tower A holds molecular sieve that traps nitrogen and lets oxygen pass.
- Meanwhile tower B depressurises to vent the trapped nitrogen and regenerate.
- The towers swap on a fixed cycle; oxygen at 93 ± 3 % is collected and supplied to the medical gas line.
What does a hospital need from its oxygen supply?
Medical oxygen must be continuous, at the concentration the standard requires, and expandable when demand grows. Three supply options exist today: liquid oxygen, cylinders and an on-site PSA oxygen generation system; each suits a different scale and set of conditions.
How C-System solves it
Novamed Vietnam’s C-System separates oxygen from ambient air by PSA with molecular sieves. The CS50 configuration produces 3 m³/h of oxygen, equivalent to about 12 40-litre cylinders a day. The modular design lets several modules be combined and switch on and off with demand; IoT monitoring reports output, concentration and alarms remotely.
Standards and regulatory documents
Outlet oxygen is 93 ± 3 % to TCVN 7742:2007 (ISO 10083:2006) and meets the European Pharmacopoeia and United States Pharmacopeia requirements. Registration numbers and medical device classification appear on the product pages as Novamed provides them.
Launch and reference projects
The CS50 and CS20 configurations were introduced on 6 January 2023 at Hospital E, Hanoi, at the conference marking the 20th anniversary of the Vietnam Medical Equipment Association. See delivered projects.
Problems hospitals bring to us
- 01.
Dependence on suppliers
Liquid oxygen and cylinders both depend on delivery schedules and market prices; when demand spikes, the hospital cannot control its own supply.
- 02.
Infrastructure and safety
A liquid oxygen tank needs a safety zone, a dedicated corridor and periodic inspection; a cylinder store takes floor space and needs in-hospital transport procedures.
- 03.
Visibility of operation
Hospital management and the equipment department need to see output, concentration and alarms in real time instead of paper reports.

Frequently asked questions
What technology does C-System use to produce oxygen?
C-System uses pressure swing adsorption (PSA) with molecular sieves: two towers alternately retain nitrogen from compressed air and let oxygen through, so the hospital produces oxygen on site instead of exchanging cylinders.
What is the oxygen concentration at the outlet?
Outlet oxygen is 93 ± 3 %, as required by TCVN 7742:2007 (ISO 10083:2006) for oxygen produced by concentrators in medical gas pipeline systems.
How do CS20 and CS50 differ?
Capacity. CS50 produces 3 m³ of oxygen per hour, about twelve 40-litre cylinders a day; CS20 produces 1.2 m³ per hour, about five cylinders. Both share the same PSA technology, 93 ± 3 % concentration and IoT monitoring.
Which standards does C-System follow?
C-System follows TCVN 7742:2007 (ISO 10083:2006) for medical gas supply systems with oxygen concentrators, together with the European Pharmacopoeia and United States Pharmacopeia requirements for oxygen 93 %.
Can the system be monitored remotely?
Yes. C-System has remote IoT monitoring and modules that switch on and off with demand, suited to facilities without round-the-clock technical staff.
