AI Driven Data Center Industry Challenges
Increasing Power Density
Higher rack densities demand more efficient and reliable cooling.
Heat Management
Traditional cooling approaches struggle to keep up with AI and HPC workloads.
Uptime is Everything
Even minor cooling issues can lead to downtime and revenue impact.
Water & Resource Pressure
Sustainability goals require smarter water management.
Complexity & Risk
More systems require expert operational support.
Fluid-to-Facility™
Lifecycle Cooling Assurance for Data Centers. ™
As rack densities and heat loads rise, data centers are increasingly integrating evaporative, dry, and hybrid heat-rejection technologies with closed-loop water and glycol systems, heat exchangers, coolant distribution units (CDUs), and technology-side cooling loops.
Although these components may be designed, installed, and managed by different teams, they operate as a single thermal system. Its reliability depends on how effectively the interfaces are planned, commissioned, monitored, and maintained.
Apex’s Fluid-to-Facility™ framework brings these elements together, providing a unified approach to lifecycle assurance across water and fluid management, cooling infrastructure, commissioning, and long-term performance.
End-to-end Data Center Infrastructure Solutions
From site selection through long-term operations, Apex helps developers, owner-operators, EPCs, and contractors minimize project risk, maximize reliability, and optimize the water and thermal system performance to support mission-critical AI and data center infrastructure.

Frequently Asked Questions
What is direct-to-chip (DTC) liquid cooling?
Direct-to-Chip (DTC) cooling is an advanced liquid cooling method that removes heat directly from high-power processors and GPUs using liquid-cooled cold plates and heat transfer fluids. By transferring heat more efficiently than traditional air cooling, DTC cooling enables data centers to support high-density AI and HPC workloads with improved thermal performance, energy efficiency, and reliability.
Why are DOWFROST™ fluids used in DTC systems?
DOWFROST™ heat transfer fluids are used in direct-to-chip (DTC) cooling systems because they provide excellent thermal stability, freeze protection, corrosion inhibition, and long-term system reliability. Engineered for closed-loop cooling applications, DOWFROST™ fluids help protect critical cooling infrastructure while maintaining efficient heat transfer for high-density AI and GPU workloads. Their proven performance and compatibility with liquid cooling systems make them a trusted solution for mission-critical data center environments.
