UK company Crestchic has provided two of its 1 MW loadbanks to the world’s first underground data centre.

The Lefdal Mine data centre is a 120,000 square metre facility in Norway based in a former mine shaft. It opened last year and is powered by four hydropower stations and two windfarms, providing a capacity of more than 300 MW.

Crestchic was asked to provide two resistive-only loadbanks. Paul Brickman from Crestchic explianed: “The underground location uses cold seawater from a neighbouring fjord as a cooling source. The seawater is passed through a heat exchanger and cooled from 30 C to 18 C to create a closed fresh water circuit, which is a very effective way of keeping the computers and servers cool.”

Crestchic loadbanks feature forklift pockets in the base and lifting eyes at high level, which Brickman said makes the loadbanks easier to transport and lift into place.

The mine consists of six levels divided into 75 chambers. The 17 metre-high chambers are wide enough to allow data containers to be stacked three-high on both sides with a transportation route in the middle.
