Pressurization systems used for high-pressure machineries are mainly categorized into two types: First is so-called “direct pressurization system”, in which volume of high-pressure vessel is directly reduced by piston. Second is so-called “indirect pressurization system”, in which pressure medium is injected into high-pressure vessel by pressure-intensifier pump. The former and latter systems are often used for food-pressurization and cold isostatic press machines, respectively. In this article, I introduce newly-created small-scale pressurization equipment and several large-scale machines provided by our corporation.
