The hospital is a 650-bed capacity facility Located at Northern Bypass near Kahawa West. The facility has at least 650 oxygen outlets at every bed available. This requires keen oxygen management practices that will help in 24hour supply to the hospital. The hospital’s medical gases unit, has three constant supply sources of oxygen to the whole hospital. These include oxygen plantsPSA (4 identical & independent), liquid Oxygen tank of 20,000 liters and compressed oxygen cylinders – 850 cylinders.
Oxygen plants – PSA
At our facility we have four oxygen plants that are identical, each plant produces 613 liters of gaseous oxygen per minute therefore this will be a total of 2,452 liters of gaseous oxygen produced from our plants per a single minute. Surprisingly during covid time this was not enough, we had to boost our PSA Plant with compressed Oxygen gas cylinders via manifold due to high population of patients at that time. Currently there is minimal consumption of Oxygen by the patient in the hospital. Therefore, we are supporting many other facilities – hospitals & public with approximately refill of 20 (8.5M3) oxygen cylinders per day.
Liquid tank
A 20,000-liter liquid oxygen tank was donated by world bank – MOH and delivered & commissioned to our facility 0n 28/09/2021. It has been in use since then as a secondary supply system to the whole hospital. Liquid oxygen (LOX) has a purity of 99.5% unlike PSA plant that has a purity of >93%.
One liter of liquid oxygen produces 861 liters of gaseous oxygen. This will translate to 20,000 *861 = 17,220,000 liters of gaseous oxygen stored in our liquid tank at full capacity. This has given us firm confidence and solved almost all the challenges we faced during covid-19 period. Liquid Oxygen tank (20,000 Litres)- Installation Commissioned 28.

Oxygen cylinders
An oxygen cylinder is a device that is used to store gaseous oxygen at high pressure. This will assist to store more volume of gas to a small container.
We own 850 oxygen cylinders with a capacity of 8.5M3 to 150 bars of pressure. This translates to 8,500 liters of gaseous oxygen per cylinder. Therefore 8,500*850= 7,225,000 liters of gaseous oxygen stored in oxygen cylinders. NB; Only for our hospital’s emergency backup.
VACUUM PLANT
The unit comprises of; Three (3) pumps, two (2) reservoir tanks Each tank has a capacity of 374kg.
OXYGEN REFILING STATION
The unit is used to refill oxygen cylinders. Capacity to refill at least 40 (8.5m3) oxygen cylinders in 24Hrs.
