Reliable, decarbonised cooling for your hospitals.

A healthcare facility demands continuous, reliable, controlled cooling. Our reference: CHU Sud Réunion hospital, cooled with deep sea water.

Hospital cooling

Cooling that can never stop.

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.

Challenges

What is at stake in your sector

Critical 24/7 cooling

Operating theatres, imaging, server rooms, pharmacy: no interruption is acceptable.

Continuous energy bill

Air conditioning is a permanent and growing cost.

Decarbonisation targets

Public facilities must sharply reduce their footprint.

The Value Park answer

Sustainable cooling, tailored to your infrastructure.

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.

Our reference

What we did at CHU Sud Réunion.

Design and project management of a very high efficiency cooling system for the hospital complex in Saint-Pierre, Réunion Island.

The context

A hospital running continuously, in a tropical climate, on an island territory where electricity is expensive and largely carbon-intensive.

The principle

Applying SWAC principles to the local context: tapping a natural cold source rather than manufacturing cooling with a chiller.

The non-negotiable

No degradation of service quality or reliability. Sized conventional backup takes over in all circumstances.

The outcome

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.

Our approach

How a project unfolds

01

Resource study

Bathymetry, thermal profile, currents. Identification of the optimal route for the intake pipe.

02

Techno-economic feasibility

Sizing against your critical needs and load curve, economic model and risk analysis.

03

Detailed design

Pipes, pumping stations, titanium exchangers, connection to the existing loop and to conventional backup.

04

Project management

Works supervision, department-by-department phasing with no interruption, commissioning and initial operation.

FAQ

Frequently asked questions

Is continuity of service really guaranteed?

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.

Can SWAC be installed on a working hospital?

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.

Which areas of the facility are covered?

Every area served by your chilled-water loop: operating theatres, imaging, server rooms, pharmacy, laboratories and wards. Existing terminals do not need replacing.

How does a public facility finance such a project?

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.

Our facility is not near the sea. What do you offer?

Energy audits and chiller refurbishment apply to any facility: regime optimisation, upgraded controls, replacement of high-GWP refrigerants, and the full regulatory dossier.
