In mid-July, in Sundern, Sauerland, the temperature was 14 degrees with light rain. Next to the L&R Kältetechnik main building, the Art of Cryo brand showroom immediately catches the eye. The first impression: violet lighting, an welcoming atmosphere, and numerous refrigeration chambers, including a device that resembles a space capsule called Flow. The focus is on the Flow application because LINAK products are installed in Flow.
