The Brief

"In 2012 STIHL were having a new 200kW data centre designed for their Virginia Beach Headquarters. Following extensive consultation it was decided that a water cooled system was to be their preferred option."

"The design specification had to meet tough criteria, including low energy consumption from a renewable source in line with their environmental policy, N+1 redundancy and due to their geographical location for the building and cooling solution to withstand a hurricane without any downtime to their operations."

The Cooling Solution

The ColdLogik team designed the most energy efficient solution for STIHL and thanks to their access to a natural underground water supply, water was taken via a bore hole from the underground springs with a nearby lake used as a back up resource this solution was naturally hurricane proof as no water towers or external plant would be required.

Because the cooling source was below ground the water supply temperature was a constant 64.4°F allowing for all year round free cooling therefore benefiting hugely on cost savings as it took less than 7.5kW to cool 200kW IT heat load.

The back up water source at the nearby lake had large coil heat exchangers deployed and a reverse cycle heat pump, this meant during the winter months the supply could switch so waste heat from the data centre could be recycled to heat their building free of charge.

The data centre itself had 10 x CL20 C8 rear coolers retrofitted to their free issue OEM cabinets via ColdLogik compliant interface frames.

The installation also benefits from having the patented Leak Prevention System designed into the solution, which gives it water tight peace of mind, so there is no risk of any water escaping from the system pipework or rear coolers.

Due to the success, cost and energy savings of this project, STIHL plan to upgrade a second data centre in their organisation in the very near future.
