For many healthcare facilities, oxygen demand does not increase all at once. It grows gradually as new departments are added, patient numbers rise, and clinical services expand. This is why hospital oxygen infrastructure is rarely built only for today’s needs. It must also be capable of supporting tomorrow’s growth.
Two recent projects completed by ZOY Technology illustrate how hospitals in different regions approach this challenge. One is a new 50 Nm³/h PSA oxygen generation installation at Luton Hospital in Kenya. The other is a long-term oxygen capacity expansion project at a rehabilitation hospital in Changsha, China, where the customer has expanded its oxygen generation capacity several times over the years as demand continued to increase.
Although the projects differ in scale and application, both reflect a common trend in healthcare: hospitals are looking for oxygen generation systems that are reliable today and scalable for the future.
One rehabilitation hospital in Changsha provides a practical example of how oxygen demand evolves over time. Today, the hospital operates around 400 inpatient beds and has continued expanding its rehabilitation and respiratory care services, making a reliable medical oxygen generation system an increasingly important part of its daily operation.
Several years ago, the hospital purchased its first PSA oxygen generation system from ZOY Technology—a 5 Nm³/h unit designed to meet its oxygen requirements at that stage of development. As the hospital expanded, increasing patient admissions and the growing demand for oxygen therapy soon exceeded the capacity of the original system.
Rather than redesigning its oxygen infrastructure from the beginning, the hospital chose to build upon its existing investment. Last year, the original 5 Nm³/h installation was upgraded to a 20 Nm³/h fully integrated containerized PSA oxygen generation system, significantly improving oxygen production capacity while simplifying system management and operational efficiency.
Earlier this year, the hospital further expanded its respiratory care capabilities by adding more than ten High Dependency Unit (HDU) high-flow respiratory devices. The increased oxygen consumption created by these new clinical services made additional production capacity essential. To meet this demand, the hospital installed a second 20 Nm³/h PSA oxygen generation system, positioned directly above the existing unit in a stacked configuration that maximized the available equipment space while doubling the total oxygen generation capacity.
Today, the hospital operates two 20 Nm³/h PSA oxygen generation systems, providing a combined production capacity of 40 Nm³/h to support its approximately 300-bed rehabilitation facility
More importantly, this project highlights a reality that is often overlooked in hospital oxygen planning: oxygen demand is rarely static. As hospitals introduce new clinical departments, high-flow respiratory therapies, or additional inpatient capacity, oxygen consumption can increase much faster than expected. By adopting a phased expansion strategy, the hospital was able to increase oxygen production capacity step by step without disrupting daily operations or abandoning previous investments.
For ZOY Technology, the project also reflects the value of long-term partnerships. The hospital's journey from a 5 Nm³/h system to a 40 Nm³/h on-site oxygen generation solution was not the result of a single installation, but of multiple stages of expansion supported by years of operational experience, evolving clinical needs, and continued trust.
While the Changsha project focused on expansion, the project in Kenya addressed a different requirement: establishing a new source of on-site medical oxygen generation.
Located in Nairobi, the healthcare facility serves a growing urban population and provides inpatient care, maternity services, diagnostic imaging, emergency treatment, rehabilitation services, and specialist consultations. With multiple clinical departments operating around the clock, continuous oxygen availability is essential for supporting patient care and daily medical operations.
To strengthen its oxygen infrastructure, the hospital installed a new 50 Nm³/h PSA oxygen generation system supplied by ZOY Technology.
The system is designed to produce medical oxygen at a purity level of approximately 93% ±3%, providing a continuous source of oxygen directly at the point of use. By generating oxygen on-site, the hospital gains greater control over supply availability while reducing reliance on external oxygen deliveries.
For healthcare facilities, oxygen availability is not simply an operational issue. It directly affects the continuity of patient care. Establishing dedicated on-site oxygen generation capacity allows hospitals to improve supply reliability and better respond to changing clinical demands.
The installation of the 50 Nm³/h system provides Luton Hospital with a stable oxygen production platform capable of supporting both current requirements and future growth.
A PSA oxygen generation system is an on-site oxygen production solution that separates oxygen from compressed air using Pressure Swing Adsorption technology.
Over the past decade, healthcare facilities around the world have increasingly adopted PSA oxygen generation systems because they provide hospitals with greater control over oxygen supply, reduce dependence on external logistics, and offer a scalable approach to long-term oxygen management.
The two projects featured here demonstrate two different but equally important approaches to hospital oxygen planning. In Kenya, a new installation established dedicated oxygen production capacity for a growing healthcare facility. In Changsha, an existing customer expanded oxygen production from 5 Nm³/h to 40 Nm³/h through multiple stages of development.
Both projects highlight the same principle: effective oxygen infrastructure should not only meet today’s requirements but also adapt to future demand.
As hospitals continue to expand services and improve patient care capabilities, scalable oxygen generation systems are becoming an increasingly important part of healthcare infrastructure planning.
A PSA oxygen generation system produces oxygen on-site by separating oxygen from compressed air through Pressure Swing Adsorption technology.
Most medical PSA oxygen generation systems produce oxygen with a purity level of approximately 93% ±3%, making them suitable for a wide range of healthcare applications.
Hospitals often increase oxygen generation capacity as patient volumes grow, new departments are added, or oxygen consumption rises beyond the capacity of the original system.
Yes. Many hospitals choose phased expansion strategies that allow additional oxygen generation modules to be integrated as demand increases.
On-site oxygen generation improves oxygen availability, reduces dependence on delivered oxygen supplies, and provides hospitals with greater operational flexibility.
