OneAsia to Launch First Immersion Cooling Solution for Data Centers in Hong Kong

OneAsia to launch an immersion cooling solution starting this September. The first of its kind in Hong Kong, the new solution significantly reduces data center energy consumption and provides more reliable performance.

It marks a groundbreaking shift for a heavy energy-consuming industry towards a greener future by adopting innovative, sustainable technologies and practices.

OneAsia is the first data center operator to provide this innovative technology in Hong Kong, and is set to expand the service to its other data centers in Greater China and East and Southeast Asia.

In recent years, advances in AI, IoT and machine learning, combined with increased computing power and performance requirements, have led to a higher server rack density – a particularly dire problem with Hong Kong's land constraints.

The result has been an upsurge in heat generated by traditional data centers, with cooling systems correspondingly consuming significantly more energy at greater cost.

By contrast, immersion cooling solutions are widely recognized for their reliability and energy and cost efficiency. They are also conveniently scalable to any size of data center.

Immersion cooling – also known as direct liquid cooling – is an innovative cooling solution that brings significant advantages over traditional air-cooling techniques, especially when applied to high-density environments such as data centers.

For facilities that feature extremely high-density racks (typically over 30 kW), air cooling simply is not sufficient to maintain the reliability of IT systems, no matter how new or optimized they may be.

For such facilities (rack power requirements are reaching close to 20 kW in many facilities, and many organizations are looking to deploy racks with requirements of 50kW or more), liquid cooling is not a choice, but a necessity.

With immersion cooling, the rack is designed specifically so that servers are inserted vertically. An immersion tank houses the servers in a dielectric bath, and utilizing a CDU, circulates cooling fluid to remove heat.
