Please read the description for an explanation!

The Supplemental Cooling Unit (SCU) supplies cooling for the galley chillers. The SCU is controlled by a seperate controller for each SCU (4 in total). These SCU controllers are also cooled with liquid because they can reach high temperatures. In the beginning of the video you see me service the SCU controller.
