CSL Behring is the world's leading manufacturer of biotechnological medicines, aiming to save lives and improve patients' quality of life. CSL Behring also leads in sustainability within the technical field, having installed an efficient central cooling system in its Marburg facility in 2023. This system, using only air (R729), was retrofitted in collaboration with our partner HOF, and features cold air refrigeration machines from Mirai Intex. It is future-proof, offering high flexibility, reliability, and efficiency, with a significantly lower carbon footprint compared to conventional systems. This technology is a true game-changer, fully complying with environmental regulations such as the F-Gas Regulation and REACH. Additionally, the process heat can be used for other processes as a heat pump. HOF Sonderanlagen is a leading manufacturer of pharmaceutical freeze-drying, freezing, thawing, and loading/unloading systems.
