Protium is a set of components for creating pump and reservoir combinations which increases performance, mounting options, flow inlet/outlet options and will be a feature in your build. We set out to create the most minimalistic and compact components, but at the same time providing the most options and compatibility. Our components are refined in ways only possible due to our 15 years of experience in liquid cooling. Each component is carved from a solid block of material on a CNC mill. Creating our different finishes, frosted and polished acrylic is unique and takes a lot of effort to manufacture. Protium is designed for enthusiasts who want to enjoy building systems with the freedom to create something individual.
