A leading example of a Japanese company adopting ORv3-compliant direct-liquid-cooling racks has been reported. NITTO KOGYO CORPORATION has established a system for handling technical specifications and individual orders, and the racks have been implemented at NVIDIA's DRIL verification facility in Inzai.
According to a newly published article, NITTO KOGYO CORPORATION has adopted ORv3-compliant racks as a leading example of liquid-cooling technology in Japan. The racks were installed at NVIDIA's DRIL, an advanced rack-scale AI server verification facility in Inzai, where racks fully compliant with the global ORv3 standard were selected. The article also mentions related examples in Taiwan and industry trends, but focuses on the specifications and application examples of NITTO KOGYO CORPORATION's direct-liquid-cooling racks. NITTO KOGYO CORPORATION is also said to be proceeding with individual-order support for ORv3-compliant racks, in anticipation of future domestic adoption. The report states that its preparation used Gemni's deep-research algorithm.
The article also explains that ORv3 stands for Open Rack Version 3 and, by supporting 21-inch-wide racks beyond the limitations of the 19-inch standard, enables new cooling and maintenance design approaches such as Zero-U manifold placement. It organizes design advantages including comparisons between 19-inch and 21-inch racks, integrated rear power distribution and simplified front-to-back access. The individual-order process and configuration requirements for NITTO KOGYO CORPORATION's ORv3 racks are presented in detail, positioning them as groundwork for future domestic adoption.
