MAX IV-laboratory, Lund Sweden.

Piller is to supply MAX IV Laboratory, a world-leading Swedish electron accelerator research facility, with uninterruptible power for its highly sensitive and sophisticated research equipment. The MAX IV-laboratory in Lund Sweden, is the brightest source of x-rays worldwide. Built for a cost of around 6 billion SEK and capable of receiving 2000-3000 scientists annually, the centre has been attracting researchers from around the world ever since its launch in 2016.

The new Piller system is a 7.5 MVA medium voltage rotary UPS expandable to 12.5 MVA, with kinetic energy storage.

Jacob Schuster, Project coordinator at Lund University MAX IV said: “Electrons are the source of the intense X-rays used for the experiments at our experimental stations. Producing these and then controlling them at the speed of light is a complex process that places high demands on the plant and the associated infrastructure.

“The MAX IV accelerator is very sensitive to variations in power supply, and the extremely short disturbances that arise from the external power grid currently result in several reboots of the plant every week. As a consequence of the interference on the power grid, research teams with limited access to the experimental stations may lose valuable time, so we are keen that the power supply to MAX IV is of very high quality.”

Jan Hermansson, Head of Division at Malmö-based APQ El, the company which will be installing the new system, said: “APQ El has carried out previous installations at MAX IV and we are pleased to have continued confidence in the delivery of our products and services. We are also pleased to be working with Piller, the partner which helped us find the optimal solution.”

Commenting on the new installation, Kristoffer Simonsson, Sales Manager for Piller Scandinavia said: “Piller is the ideal partner and we can assist with our knowledge and long experience of similar projects. I am confident that our products will assist with the protection required for such a technologically advanced and critical facility, for many years to come.”

Piller, a leader in power protection technology, builds electrical systems for mission-critical applications worldwide. Clients include many of the world’s central and commercial banks, stock exchanges and other financial institutions, as well as broadcasters, airports, telecommunications networks, government departments and co-location operators.
