Ludwigsburg / Düsseldorf (Germany), September 19, 2025 - bluu unit GmbH, a Triton Smaller Mid-Cap Fund II portfolio company and a rapidly growing alliance of regionally strong companies in the field of sustainable refrigeration, air conditioning, and ventilation technology, has signed an agreement with SüdBG, founder Andreas Kohmann, and the involved management team, Patrick Peters and Ingo Hoffmann, to acquire KKL Holding GmbH based in Düsseldorf. Through this transaction, bluu unit gains one of Germany’s most distinguished specialists in refrigeration, air conditioning, ventilation technology, and data centre solutions.

KKL manages projects across all industries—with a strong focus on data centres. The company’s service portfolio covers a wide range of modern refrigeration and air conditioning technologies. While the alliance leverages its strength in sustainable technologies, a broad service portfolio, and a nationwide network, KKL contributes valuable expertise in training, paired with high quality standards and close customer relationships—values shared by bluu unit.
KKL’s nationally largest training centre for refrigeration and air conditioning technology, with a 100% graduation rate, makes it a lighthouse of talent development in the industry.
