Quantum Mesh Establishes Liquid Immersion Rack Showroom at Ginza Headquarters; Exhibiting the Actual Unit of Independently Developed “KAMUI” Liquid Immersion Cooling System for AI Data Centers

Quantum Mesh Inc. (Pronunciation: Quantum Mesh / Headquarters: Chuo-ku, Tokyo; Representative Director: Hiroyuki Shinohara; hereinafter "Quantum Mesh") announces that it has opened a showroom displaying the actual unit of its independently developed liquid immersion cooling system "KAMUI," which achieves high energy efficiency with a PUE of 1.03※1. This showroom is opened as a place where companies considering purchase and introduction, as well as members of the press, can directly touch the actual unit to experience its performance and quietness.

The latest GPU server system "Hydro Booster," announced and launched in April 2025, has attracted significant attention as a next-generation server that dramatically improves cooling efficiency and high-density GPU deployment by adopting the "KAMUI" liquid immersion cooling system independently developed by the company, and has received numerous inquiries.

Currently, the actual unit is operating only at the data center in Takahama Town, Fukui Prefecture, operated by the company, meaning opportunities to view the actual product were limited. To this end, the company has installed the actual unit at its Ginza headquarters, opening a permanent showroom to accommodate visits.

In the showroom, visitors can actually check the size and quietness of the liquid immersion rack. In the future, the company will also introduce practical products such as AI robots on the same floor to create a space where visitors can understand data center use cases more concretely.

※1: PUE (Power Usage Effectiveness) is an index showing "the power efficiency of IT equipment relative to total power consumption of the data center," with 1.03 being a world-class level (according to Quantum Mesh research).

Guidance is available by prior appointment only.
