Ready Server Pilots Full-Immersion Cooling to Prepare Singapore Facility for AI-Ready Compute Services

VPS provider deploys self-built liquid cooling solution to increase rack density and energy efficiency amid surging compute demand

SINGAPORE, July 30, 2026 /PRNewswire/ -- Ready Server, a Singapore-based VPS hosting and server solutions provider, has completed its first pilot of full-immersion liquid cooling at its data centre facility in Singapore. The initiative marks a key step in the company’s roadmap toward delivering AI-ready infrastructure services.

The pilot involves immersing complete server hardware—production-grade AMD-based servers with memory and storage components—into a tank of non-conductive immersion cooling fluid. The hardware is supplied by GRC, a US-based liquid cooling specialist. The immersion cooling fluid transfers heat away from server components far more efficiently than air, enabling higher rack densities and potentially reducing cooling energy consumption.

Meeting the Demands of the AI Era

Global demand for high-performance compute, accelerated by AI workloads, is pushing data centre operators worldwide to rethink how densely and efficiently servers can be deployed. As computing systems become more powerful and valuable, operators are seeking more efficient cooling technologies to maximise performance while making better use of existing space and power resources.

Rather than purchasing fully packaged immersion-cooled systems, Ready Server opted for a self-deployed solution—designing a customised setup tailored to its existing facility. This approach reduces capital costs while building in-house engineering capability in liquid-cooled operations.

"Everything comes with a risk, so we have to take some that will enable us to compete and deliver the performance needed in the future," said Alan Woo, Director of Ready Server, who personally oversaw the import and installation of both the cooling tank and immersion cooling fluid.

A Pragmatic, Phased Approach

Ready Server's pilot methodology reflects careful risk management:

• Servers selected for immersion have already operated in racks for approximately two years—nearing the end of their manufacturer warranty—since immersion and hardware modifications can affect warranty coverage.
• Components are prepared prior to immersion: cooling fans are removed, thermal paste is replaced with a thin metal foil suited to liquid-cooled operation, and certain paper labels or adhesive stickers are removed, as prolonged exposure to the fluid can cause them to deteriorate.

Compared with alternative liquid cooling methods the company has previously trialled, including spray-based coolant jets, the full-immersion approach offers simpler maintenance and continuous 24/7 operation, and reduces the risk of coolant leaks associated with direct-to-chip liquid cooling.

Building Toward AI-Ready Services

The pilot delivers benefits beyond electricity savings: it equips Ready Server with the operational experience needed to design future rack architectures for compute-intensive workloads.

"This journey into liquid cooling has taught us valuable lessons in designing our future racks and how we can deliver more compute-heavy services to customers," said Woo. "By investing in the technology and also the capabilities to run it, we are more ready to offer new services that the market is asking for."

Ready Server plans to apply learnings from the pilot as it expands its portfolio of high-density hosting and AI-ready data centre services in Singapore.
