IRIE KOKEN accepts orders for manufacturing chambers in which the inside is a special environment that can be changed from an ultrahigh vacuum to an atmospheric pressure, a plasma environment, a lean active gas environment, etc., including gate valves.



Surface treatment


We also manufacture chamber bases together.
