Trinity Biotech Launches Trinovium to Bring Healthcare-Grade Fluid Technology to the Rapidly Growing Multi-Billion Dollar AI Data Center Liquid Cooling Market
- New subsidiary will leverage existing US and EU manufacturing capacity, high-purity fluid expertise, and analytical technologies to target liquid cooling performance and reliability in AI and high-performance computing environments
- Data center liquid cooling market is projected to grow from $4 billion in 2026 to $27 billion by 20331
DUBLIN, Ireland and Wilsonville, Oregon (June 23, 2026) - Trinity Biotech plc (NASDAQ: TRIB), a commercial-stage biotechnology company focused on human diagnostics and diabetes management solutions, today announced the launch of Trinovium, a dedicated subsidiary focused on advanced liquid cooling solutions and fluid intelligence systems for next-generation AI data centers. As escalating AI workloads increase compute density and heat generation, driving a rapid industry transition from air cooling to liquid-cooled infrastructure, Trinovium will leverage Trinity's expertise in ultra-high-purity fluid manufacturing, analytical technologies, and large-scale production capabilities to address the growing reliability challenges associated with next-generation liquid cooling systems.
The data center liquid cooling market is projected to grow from $4 billion in 2026 to $27 billion by 2033, representing a 31.5% CAGR (2026, MarketsandMarkets)2, driven by increasing AI compute density and the growing adoption of liquid-cooled infrastructure. Independent industry research similarly projects sustained double-digit growth over the coming decade as conventional air-cooling approaches reach practical performance limits345.
As Trinity Biotech’s operational transformation plan now reaches its final stages, the Company is able to redirect a portion of its existing United States and European Union manufacturing capacity—capable of producing millions of liters of high-precision fluids annually—to support Trinovium. This provides a capital-efficient path into the liquid cooling market while creating the potential for additional operating leverage from existing assets.
The Company has developed an initial direct-to-chip liquid cooling formulation designed around three core performance requirements and the relevant Open Compute Project guidelines:
• Ultra-high-purity, highly stable aqueous chemistry;
• Corrosion inhibition, and coolant system protection; and
• Healthcare-level consistency and traceability.
“This strategy expands our capabilities into one of the most important infrastructure layers underpinning AI and builds upon our work developing AI-powered diagnostics,” said John Gillard, Chief Executive Officer of Trinity Biotech. “We are leveraging what we do today at an exceptionally high standard, manufacturing ultra-high purity, highly stable fluids, and applying it to AI infrastructure – one of the fastest-growing segments of global compute and a market where performance, reliability, and quality are increasingly mission-critical.”
Building upon Trinity Biotech’s expertise in healthcare-grade fluid manufacturing, the launch addresses one of the most pressing infrastructure challenges in AI deployment: the rapid shift from air to liquid cooling driven by escalating compute density. As advanced GPU architectures push power loads beyond what air cooling can manage, companies with expertise in liquid cooling are becoming mission-critical to the companies building the next generation of AI infrastructure.
Trinovium is entering a market where rising power densities are making coolant purity, stability, and monitoring increasingly important to system reliability. As coolant temperatures and operating demands increase, factors such as corrosion, particulate contamination, fluid degradation, and microbial growth are becoming increasingly important determinants of system reliability and uptime. Historically served by industrial chemical suppliers and industrial-grade quality systems, the market is now placing greater emphasis on coolant formulation and quality as a contributor to uptime, corrosion control, flow stability, and thermal performance. Poor fluid performance can create oversized economic risk for capacity-constrained AI infrastructure.

Alongside its initial direct-to-chip cooling fluid formulation, the Company is working to advance a fluid health and system intelligence platform drawing on its broad analytical technology portfolio, including connected electrochemical sensing and mass spectrometry capabilities acquired through recent strategic transactions. The platform is being designed to monitor corrosion and scaling, particulate contamination, and microbial growth and biofilm formation, creating a high-margin, recurring revenue layer that moves the business model toward data-driven performance optimization. Trinovium’s activities will now focus on technical validation, partner engagement, and customer qualification pathways for AI and high-performance computing environments.
The launch draws on Trinity Biotech’s experience at the intersection of hyperscale infrastructure and advanced technology, including board and leadership experience across major technology and large-scale infrastructure companies. Chief Executive Officer John Gillard previously held senior roles at large-scale infrastructure and technology companies, including Google. This experience supports Trinovium’s understanding of the operational, reliability, and qualification requirements of enterprise data center customers.
“We believe Trinovium positions Trinity Biotech as an emerging AI infrastructure enabler, not just as a supplier, but as a partner helping customers maximize system performance,” Gillard added. “With a capital-efficient entry point, exposure to a rapidly scaling market with faster innovation cycles than healthcare, and a recurring analytics layer, this initiative has the potential to materially and rapidly reshape how Trinity Biotech is positioned and valued.”
In parallel with the launch of Trinovium, Trinity Biotech continues to commercialize its core healthcare portfolio, including the U.S. Food and Drug Administration (“FDA”) 510(k)-cleared Premier Hb9210™ HbA1c analyzer, the FDA 510(k)-cleared Premier Resolution system for hemoglobin variant detection, and the World Health Organization-prequalified Uni-Gold HIV and TrinScreen HIV rapid tests, and continues development of its next-generation continuous glucose monitoring solution, CGM+.
