Electronic Thermal Fluids
Direct Liquid Cooling
As artificial intelligence (AI), high-performance computing (HPC), and hyperscale data centers continue to increase processor power and rack densities, efficient thermal management has become critical. Direct Liquid Cooling (DLC) removes heat directly from CPUs, GPUs, and other high-performance components using cold plates and a liquid coolant loop, delivering significantly greater cooling efficiency than traditional air cooling.
Soltex Opticool® PG coolants, including PG25, PG35, and PG55, are specifically formulated for data center liquid cooling applications. These fluids provide excellent heat transfer, low corrosion, long-term material compatibility, and support for OCP-compliant cooling systems. They are designed for both Technology Cooling System (TCS) loops that cool IT equipment directly and Facility Water System (FWS) loops that transfer heat away from the data center.
Key Benefits
- Efficient heat transfer for AI, HPC, and cloud computing workloads
- Low corrosion to protect cooling infrastructure
- OCP-aligned performance requirements
- Support for both TCS and FWS cooling architectures
- Reliable performance across a wide range of operating climates
- Improved energy efficiency and reduced cooling costs
