BSR.010 – 2 megawatt ewers cold transfer station for cooling a generator
2022-09-16
Initial situation
In Greifswald, the Max Planck Institute for Plasma Physics (IPP) operates the Wendelstein 7-X experimental facility.
This 2-megawatt station, made entirely of corrosion-resistant stainless steel grade 1.4571, is used to cool the RF generator of a facility for researching nuclear fusion technology with refrigeration from a refrigeration plant. The cooling capacity is adjusted by a speed control of the circulating pump in the cooling circuit of the generator. The pump is controlled by a Profibus signal.
The station is equipped with a screwed plate heat exchanger designed for high throughput. The unit is also equipped with electronic sensors to detect temperatures and pressure. These sensors are connected to the central control system via a bus system.
