On Tuesday, June 3, 2025, Puretecs and its partner Soltex were at the Battery Show Stuttgart.
Soltex specializes in cooling oils. Puretecs represents Soltex products exclusively in Europe. Accordingly, the visit to the Battery Show was all about immersion cooling: the cooling of electric motors, wiring harnesses, and especially battery packs directly with a synthetic cooling oil. This is made possible by the electrically insulating properties of these highly specialized coolants, such as Opticool H.
