ExaScaler

Established on April 1, 2014, ExaScaler Inc. is a Tokyo-based company specializing in advanced thermal management solutions for high-density computing environments. The firm engineers and markets submersion liquid cooling systems tailored for supercomputers and high-performance computing (HPC) systems housed in data centers.

ExaScaler's core technology centers on a proprietary liquid immersion cooling method. This approach involves completely submerging system substrates, including all components like power supply units and storage drives, in a non-electrically conductive, high-boiling-point fluorocarbon liquid. This technique facilitates homogenous and highly efficient heat dissipation from all electronic parts, a distinct contrast to more common liquid cooling methods that target only primary semiconductors. The primary benefit for clients is a significant reduction in the energy consumption and high energy dependence typically associated with large-scale computing infrastructure.

The company operates in the B2B market, serving research institutions and enterprises that require substantial computing power. A notable collaboration exists with PEZY Computing, where ExaScaler provides the cooling technology for supercomputer development projects. This partnership has resulted in installations at prominent Japanese research institutions, including the Shoubu supercomputer at RIKEN, which achieved a top ranking on the Green500 list for energy efficiency. ExaScaler has secured funding from institutional investors, including Japan Asia Investment and Mistletoe, through a seed round in November 2014.
