Critical 24/7 cooling
Operating theatres, imaging, server rooms, pharmacy: no interruption is acceptable.
A healthcare facility demands continuous, reliable, controlled cooling. Our reference: CHU Sud Réunion hospital, cooled with deep sea water.

continuity of service, with sized conventional backup
In a healthcare facility, cooling is not a comfort. Operating theatres, imaging, server rooms, pharmacy and laboratories require permanently controlled temperature and humidity, with a tolerance for failure close to zero.
That continuity requirement comes with budget and regulatory pressure. Air conditioning is a permanent and growing cost, while public facilities are required to cut their energy consumption sharply.
The two objectives look contradictory. CHU Sud Réunion shows that they are not.

Air conditioning is a permanent and growing cost.
Public facilities must sharply reduce their footprint.
At CHU Sud Réunion, we apply SWAC to target up to 90% less cooling electricity, with no compromise on reliability. Design, project management, integration with the existing plant and conventional backup: we secure every step.

Up to 90% less cooling electricity
Reliability and redundancy
No fluorinated gases
Design and project management of a very high efficiency cooling system for the hospital complex in Saint-Pierre, Réunion Island.
A hospital running continuously, in a tropical climate, on an island territory where electricity is expensive and largely carbon-intensive.
Applying SWAC principles to the local context: tapping a natural cold source rather than manufacturing cooling with a chiller.
No degradation of service quality or reliability. Sized conventional backup takes over in all circumstances.
A 90% cut in cooling-related electricity, on a site where interruption was not an option.
A hospital is often seen as the riskiest place for a new technology. It is in fact where it proves itself best: if continuity holds in a 24/7 hospital environment, it holds anywhere else.
01
Bathymetry, thermal profile, currents. Identification of the optimal route for the intake pipe.
02
Sizing against your critical needs and load curve, economic model and risk analysis.
03
Pipes, pumping stations, titanium exchangers, connection to the existing loop and to conventional backup.
04
Works supervision, department-by-department phasing with no interruption, commissioning and initial operation.
Yes, it is a design prerequisite. Conventional backup is sized to take the full load, and critical components, pumps and exchangers, are redundant. SWAC acts as the primary cold source, not the only one.
Yes. The loop is built alongside the existing plant, which stays in service. Connection is phased department by department, within windows agreed with technical and medical teams.
Every area served by your chilled-water loop: operating theatres, imaging, server rooms, pharmacy, laboratories and wards. Existing terminals do not need replacing.
Structures vary with the status of the facility and the schemes available at the time. The techno-economic feasibility phase always covers financing scenarios alongside technical sizing.
Energy audits and chiller refurbishment apply to any facility: regime optimisation, upgraded controls, replacement of high-GWP refrigerants, and the full regulatory dossier.
