HONG KONG, Dec. 9, 2025 /PRNewswire/ -- The Hong Kong Polytechnic University (PolyU) continues to advance interdisciplinary learning with the launch of its second course under the Advanced Education Programme, offered by the PolyU Academy for Interdisciplinary Research (PAIR).
Beginning in Spring 2026, the new course, "Sustainable Cities", will run for thirteen weeks and cover five applied science areas, including urban informatics, sustainable urban systems and technologies, smart energy systems, land and environmental management, and resource engineering with carbon neutrality. Designed by PolyU experts, the programme equips learners with knowledge of pressing global challenges, PolyU-led innovations addressing them, and technological challenges in related fields.
The course is open free of charge to eligible members of the public, requires no prior background, and is available in dual mode — in-person or online — to accommodate learners in Hong Kong and abroad. Participants who meet attendance requirements may apply for a certificate of completion.
Enrolment closes on 31 December 2025, with limited quota for physical attendance and online places available on a first-come, first-served basis.

Supporting future-ready cities: PolyU launches free advanced education course on sustainable city developments
SANTA CLARA, Calif., Sept. 20, 2026 /PRNewswire/ -- Under the DUO POWER BOOST theme, Clivet made the global debut of its Next-Gen Magnetic Levitation Technology at AI Infra Summit 2026 in Santa Clara, California. The company also presented a portfolio of cooling sources, liquid cooling distribution, and supporting products for data centers, alongside a joint power-and-cooling coordination solution with CLOU.
According to the company, rising AI computing densities are placing growing pressure on data center cooling, with high-temperature performance degradation, energy efficiency bottleneck, and reliability risks as key challenges. General-purpose cooling technologies can no longer meet the specific needs of data centers, driving demand for AIDC-optimized thermal management solutions.
The portfolio's core is Clivet's next-generation magnetic levitation compressor, built on the DUO POWER BOOST dual-rotor variable-speed architecture. In a two-stage compression structure, two rotors and their impellers can adjust speed independently based on operating conditions, adapting to different flow rates and pressure ratios. According to Clivet, this design brings data center load variations, water temperature conditions, and system operating strategies into cooling source design, supporting optimization under complex conditions.
Addressing cooling needs across the data center, Clivet displayed a portfolio comprising magnetic levitation cooling sources, magnetic CDUs, high-capacity CDUs, fan walls, and terminal units. The air-cooled magnetic levitation chiller serves facility-side cooling, while the magnetic CDU combines cooling source and liquid cooling distribution functions.
A high-capacity CDU displayed at the event handles secondary-side heat exchange and distribution, with capacity ranging up to 3 MW (at 3K approach temperature difference, ATD) or 5 MW (at 5K ATD). Predictive temperature control keeps fluctuations within ±0.5°C, while key components support online replacement, helping ensure continuous operation in high-availability environments.
Through different product combinations, the solution can be configured according to project climate conditions, rack density, and supply requirements.
In addition, Clivet and CLOU jointly demonstrated a power-and-cooling coordination solution for AI workloads. CLOU provided energy storage and power delivery capabilities, while Clivet delivered thermal management products and solutions for high-density computing environments. For high-density computing projects, power configuration, thermal design, space layout, and operation and maintenance planning need to be considered simultaneously in the early stages of a project.
Coordinated planning of power and cooling aims to help customers assess the relationships between different infrastructure links from a system perspective, providing a reference for subsequent solution design and engineering delivery.
From a portfolio covering facility-side, liquid-cooling, and outdoor heat rejection stages, to the power-and-cooling coordination showcase, and to the launch of the next-generation magnetic levitation compressor, Clivet's appearance at the event presented its technology and product layout for data center thermal management.
