In high-tech fields such as semiconductor manufacturing, precision electronics, and laboratory research, strong acid and alkali solutions such as hydrofluoric acid, sulfuric acid, and nitric acid are often needed to achieve ideal process effects.

In semiconductor manufacturing, the etching process is a key process for accurately transferring photoresist patterns onto silicon wafers, and its quality directly determines the performance and yield of the product. Temperature changes can significantly affect the etching rate, selectivity, and process stability.

Recently, Hangzhou Pioneer Thermal Power has made an important breakthrough in the overseas market - our two independently developed water-cooled chillers FCCA33121-4401 and FCCA56121-4401 have been successfully introduced into Japan's RIKEN laboratory and achieved "zero defect" delivery.
