3 E Network Adds Digital Twin Layer to Finland AI Center

A rack designed to dissipate more than 100 kilowatts of heat is becoming the planning benchmark for 3 E Network Technology Group’s Mikkeli AI data center in Finland.

The Nasdaq-listed company, ticker MASK, said September 14 that it is combining computational fluid dynamics, or CFD, with a digital twin of the facility. The system is intended to model conditions from individual compute nodes through liquid-cooling networks, airflow containment, electrical infrastructure and outdoor cooling equipment.

That matters because AI clusters do not behave like conventional cloud installations. During large model-training runs, synchronized servers can produce abrupt power and heat surges, putting pressure on cooling systems that may look adequate under average-load assumptions. 3 E Network said its simulations will test those transient conditions and examine potential thermal “shadowing” created when high-density hardware is stacked inside racks.

The company is also using local weather data from Mikkeli to study how chillers, exhaust systems and prevailing winds interact. Finland’s climate can support periods of free cooling, but poor equipment placement could recirculate hot air and erase some of that benefit.

The digital twin is meant to remain useful after construction. Before new liquid-cooled racks are installed, operators could test pipe routing, equipment clearances and structural loads in a virtual replica. Once the center is running, sensor data would be compared with modeled conditions so cooling equipment and pumps can respond to workload-driven changes rather than simply follow fixed settings.

3 E Network previously said the Mikkeli blueprint is designed for compatibility with Nvidia’s Vera Rubin architecture, placing the project in the race to support increasingly power-hungry AI systems. The company’s Finnish subsidiary, Aurora Core Technology Oy, is identified in its SEC filings as a data-center construction business, and the company reported in April that site clearance had been completed and earthworks were underway.

The announcement adds engineering detail, not financial scale. 3 E Network did not disclose new capacity, capital spending, customer commitments or an operating date. Its fiscal 2025 annual report showed revenue of about $4.8 million, primarily from software development services, underscoring how early the shift toward large-scale AI infrastructure remains.

For MASK investors, the next proof points are physical construction, hardware commitments and operating data on rack density, cooling efficiency and power usage.
