In semiconductor manufacturing, agitators are mainly used for conditioning polishing and cutting suspensions, etchants and other auxiliary chemicals, cleaning solutions, or for chemicals recycling. The requirements placed on stirring systems are extremely demanding.
Clean room conditions prevail in almost all applications, which means drives and seals must be designed without abrasion or leakage. Due to the aggressiveness of the media and the purity requirements, product-contact parts such as the shaft and stirring element often have to be produced with metal-free surfaces.
Geppert Rührtechnik has a long and successful history in this field. All well-known chip manufacturers belong to our client base, as do manufacturers of the specialty chemicals used in this field. Our agitators are also used in broad areas of solar cell production. Year after year, Geppert supplies a significant proportion of agitators to a group of satisfied customers for both chip and solar cell manufacture.
