en.Wedoany.com Reported - Hydroniq Coolers, a supplier of ship cooling systems headquartered in Ålesund, is extending its marine seawater cooling technology to onshore data centers. The company typically integrates coolers into ship hulls and now sees opportunities to apply this technology to data center cooling.

Inge Bøen, CEO of Hydroniq Coolers, stated that from an environmental perspective, recovering waste heat from data centers for district heating is the optimal solution. However, many data centers currently use large industrial cooling fans to cool server clusters, consuming significantly more energy than using water as a natural cooling medium.
Water-based cooling solutions are suitable for data centers located near water sources such as oceans, lakes, or rivers.
Marine cooling systems typically use seawater to lower the temperature of ship engines and auxiliary equipment. The principle of using heat exchangers to cool or heat water is identical on land and at sea. The company has previously supplied coolers to the Hydro Sunndal aluminum plant, the Tonstad hydroelectric power station in Agder, and the Wärtsilä research, development, and manufacturing center in Vaasa, Finland.
In data center applications, Hydroniq Coolers' heat exchangers will be connected to existing data cabinets and placed outside the data center. The cooler receives water heated by the data center, reduces its temperature through the heat exchanger, and then returns the cooled water to the data center, creating a continuous circulation loop.
Inge Bøen added that this is an energy-efficient and proven cooling method that, unlike industrial cooling fans, does not generate noise for the surrounding environment. Hydroniq Coolers specializes in seawater cooling and heating—a challenging medium—but its products are equally suitable for freshwater.
Hydroniq Coolers designs, manufactures, and assembles rack-mounted seawater coolers at its headquarters in Ellingsøy, just outside Ålesund. Inge Bøen concluded that data centers are becoming an important industry in Norway and expressed hope that the sector will consider Norwegian solutions to meet cooling needs, noting significant opportunities for cross-industry collaboration in building a domestic data center ecosystem.
