CERN laboratories sit across the Franco-Swiss border near Geneva and were founded in 1954. CERN hosts nearly 13,000 visiting scientists and engineers representing 399 universities and research facilities per year, across 23 member states, and provides a hub for CERN community nearly 16.500 members. Together, scientists, engineers and technicians build and run accelerators, detectors and computing infrastructure, to probe the fundamental structure of the universe.

CERN is also home to the Large Hadron Collider (LHC), the most powerful particle accelerator ever built. The accelerator sits in a tunnel 100 meters underground at CERN, the European Organization for Nuclear Research, on the Franco-Swiss border near Geneva, Switzerland. The 27 km long accelerator is used to boost beams of particles to high energies before they are made to collide with each other. The process gives the physicists clues about how the particles interact and provides insights into the fundamental laws of nature.

Daikin chillers are used to meet CERN’s facilities needs in terms of process cooling. They provide cooling for data centres, for various experiments currently conducted at CERN and for the air conditioning systems of the underground tunnel where the Large Hadron Collider sits.


Total cooling capacity: 31MW

Units installed: most of the product portfolio


All facilities at CERN, and particularly the Large Hadron Collider, require cooling on an unusually high scale, plus absolute precision in terms of temperature control.

Besides great reliability, CERN also looks for outstanding energy efficiency and low environmental impact, to comply with their environmental policy.


Daikin has been supplying wide range of solutions to CERN, from small capacity scroll compressor units, low noise emission units to high efficiency inverter driven products and high-capacity centrifugal chillers.

All those products, despite different in terms of technology and capacity, all have common traits that define Daikin as a brand - reliability, energy efficiency and environmentally friendliness - thanks to the advanced technology, in combination with the wide choice of low GWP refrigerants.

Anders Andersen – Cooling & Ventilation Group at CERN – said about Daikin:

“We have been working with Daikin for several years now, so we have a lot of experience with them. Daikin chillers have proved to be reliable and able to satisfy the needs of CERN applications”.
