Product applications

GEMÜ CleanStar for use in DFS Fusion chemical blending systems

Chemicals are used in semiconductor production in virtually all processes, in particular for purifying, coating and etching. The corrosive, ultra-high purity chemicals used there set stringent requirements in terms of the purity and resistance of the system and its components. This is why diaphragm valves made of high-quality fluoropolymer plastics are particularly recommended for chemical mixing and supply systems. Discover the DFS Fusion chemical blending system, as an example, to find out more about GEMÜ's products and solutions, which are ideally suited for semiconductor production.
