Daiichi Jitsugyo Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President & COO: Yuji Funawatari, hereinafter “DJK”), a general machinery trading company, will jointly exhibit with Germany-based PURPLAN GmbH (“PURPLAN”) at Data Centre World Madrid, part of TECH SHOW MADRID, to be held in Madrid, Spain, from November 4 to 5, 2026.
Against a backdrop of growing demand for data centers across Europe, DJK and PURPLAN will offer one-stop solutions that combine DJK’s equipment supply capabilities with PURPLAN’s extensive piping installation expertise across the region. At the exhibition, the companies will showcase solutions that support reliable data center operations, reduce power consumption, and facilitate equipment deployment.

■ Power Solutions
The widespread adoption of generative AI is driving a sharp increase in demand for AI server computing capacity, accompanied by a substantial rise in power consumption per server rack. DJK will showcase a prototype of a next-generation, high-efficiency power supply unit (DC-DC converter) rated at 125 kW in a 1U* form factor, designed to address anticipated future power requirements of 1 MW per rack. Combining advanced power semiconductor technology with a proprietary circuit design, the unit reduces power conversion losses and helps improve the efficiency of power delivery in data centers.
Ensuring the safety of power supply equipment is also essential to reliable data center operations. DJK will exhibit an uninterruptible power supply (UPS) system from HOBE ENERGY, equipped with semi-solid-state batteries designed to reduce fire risk by limiting the amount of electrolyte used. Through this solution, DJK aims to enhance power supply safety and support reliable operations.
*A rack unit (U) is a unit of measurement for the height of equipment mounted in a server rack. 1U = 1.75 inches (approximately 44.45 mm).

■ Liquid Cooling Solutions: Secondary-Side Piping and Load Bank Systems with Commissioning Support
To efficiently manage the substantial heat generated by AI servers, DJK provides cooling systems through engineering capabilities that encompass both cooling equipment supply and liquid-cooling piping design and fabrication. In addition to offering high-performance coolant distribution units (CDUs) that help reduce data center power consumption while efficiently cooling high-density servers, DJK works with PURPLAN and KANNETSU THERMAL ENG. CO., LTD. (“Kannetsu”) to provide liquid-cooling piping design and fabrication for both secondary and primary circuits, enabling comprehensive thermal engineering.
Before a data center enters full operation, commissioning is essential to verify cooling system operation and performance, and load banks are required to simulate operating loads during testing. To meet these needs, DJK will also showcase a rack-mounted load bank currently under development by Kannetsu. This solution supports cooling system performance verification to help ensure a smooth start to data center operations.
