Dong Energy, Denmark

New Build Data Center

The Client

DONG Energy was established in 2006 by the merger of six Danish energy companies: DONG, Elsam, Energi E2, Nesa, øbenhavns Energi and Frederiksberg Forsyning.

It was created as a vehicle to develop Danish energy activities. The company has expanded significantly through organic growth and acquisitions both in Denmark and across Europe.

The merger brought together a wide range of experience, resources and activities, including oil and natural gas exploration and production, electricity generation at power stations and renewable energy facilities and natural gas and electricity distribution.

DONG Energy is one of the leading energy groups in Northern Europe. Their business is based on procuring, producing, distributing and trading in energy and related products in Northern Europe. DONG Energy has around 6,500 employees and is headquartered in Denmark. The Group generated DKK 73 billion (EUR 9.8 billion) in revenue in 2013.


The Brief

"In 2009 Dong Energy required an energy efficient cutting edge design for the cooling of their state of the art new build data centre in Denmark."

"The site had to retain a small footprint whilst maximising the density and be highly efficient 340kW - for this they requested 15kW - 30kW capacity for each cabinet of the 23 cabinets including 6 IBM SAN cabinets."

"The water supply temperature of 15°C was required for the chillers and dry air cooler they opted for in their external space."

The Cooling Solution

We installed 23 x USpace ColdLogik compliant 42U cabinets with CL20 C8 rear coolers within the white space of the data centre build.

This enabled them the packaging densities required with capacity to increase heat loads in the future within the same footprint.

Each rack had the cooling capacity of 7-30kW giving them a total of 340kW.The IBM SAN racks had to retain their EMC so we gave them our unique solution of overhead runners to enable this to happen.

The external plant comprised of 2 chillers and a dry air cooler which ran at 15°C water temperature were brought together and controlled the entire solution via a small RMS.

As the ColdLogik solution offered a 90% saving on the CRAC based design Dong Energy had previously been quoted for, they have subsequently replaced an existing CRAC based system with ColdLogik CL20’s and are planning further upgrades in the future.


Environmental Award

In 2013 Dong Energy received the Energy Globe environmental award demonstrating their commitment to sustainability and efficiency throughout their company ethos.

The energy efficiency and environmental savings associated with the ColdLogik solution was a major factor in their selection of ColdLogik throughout their many data centre projects.

Client Comments

"Since having the system installed we have now replaced other CRAC based systems with ColdLogik and are planning further upgrades to ColdLogik in other Dong Data Center projects."
