Seawater Air Conditioning for luxury hotels

The search of alternative energy sources has become a crucial aspect in the lives of all of us, and Resinex does not hold back when it comes to participating in projects related to environmental sustainability.

In 2018 it started indeed a cooperation with Rovotik, a Tahiti-based company that deals with inspections and operations upon submarine structures.

Rovotik asked to provide floats and chain-through buoys for 900 m depth filled with syntactic foam material, that guarantees high resistance and a zerowater absorption rate. The floats were utilized for a SWAC project, consisting in the installation of a private air-conditioning system using deep-sea water (“SWAC”- Seawater Air Conditioning) for a luxury hotel in Bora Bora, French Polynesia. It has been conceived and developed by Pacific Beachcomber, a company that owns and manages luxury hotels in French Polynesia.

With the support of Resinex floats, a pipeline was installed by Rovotik in seawater at a depth where the water is ice-cold all year. The water is then distributed through the air-conditioning system of the hotel through an exchanger.

The project has been a great success, as it shows that it is possible to air condition buildings without the use of highly polluting fuels and at a very competitive cost.
