Picture of the Month

A Critical Power Module (CPM) with a flywheel from Piller was installed at Jungfraujoch by Bimex Energy AG in Uetendorf. The CPM with the POWERBRIDGE kinetic energy storage system guarantees a smooth transition to standby generator operation. The CPM300 is housed in two robust steel cabinets. One cabinet contains the flywheel mass and the heat exchanger system, the other the control and power electronics. The CPM is installed in a specially extended cavern near the old Sphinx-elevator and enables that in the event of a power failure, the power supply of the laboratories and instruments in the Sphinx is guaranteed until the emergency generators are switched on.
