What is District Cooling/SWAC

The main idea of District Cooling/SWAC (Sea Water Air Conditioning) is to use local sources for cooling that otherwise would be wasted or not used, in order to offer the local market a competitive and high-efficient alternative to the traditional cooling solutions.

With 5–10 times higher energy efficiency the CO2 impact can be reduced with 80-90% compared with conventional cooling. Also the effluents of hazardous Freon can be reduced to the same extent. District cooling has a high degree of operational reliability (up to 99,9%) as well as accessibility that makes it suitable for demanding facilities such as hospitals, data centers, industries and airports.


SWAC is a renewable energy system that uses cold seawater from the ocean depths as a coolant for air-conditioning systems of buildings

SWAC is a well-established and proven technology with systems in operation around the world for more than 20 years.
