AI workloads, edge computing, and high-density GPU infrastructure are increasing thermal loads beyond what traditional air-cooling systems can handle. Higher rack densities demand cooling solutions that enhance uptime, scalability, serviceability, and reliability.
DOWFROST™ LC is an inhibited propylene glycol-based heat transfer fluid designed specifically for liquid cooling systems where thermal performance, corrosion protection, freeze protection, and system compatibility are critical. Its primary applications in data center environments are Direct-to-Chip cooling and support for in-rack closed-loop and in-row close-coupled cooling systems.

Why Data Centers Are Moving Toward Liquid Cooling

Traditional air cooling has supported data centers for many years, but the rise of high-density compute is changing cooling requirements. As more heat is generated at the rack level, operators need cooling systems that can manage thermal loads without increasing facility footprint, maintenance complexity, or energy demand.
Liquid cooling technologies offer targeted heat removal for high-performance computing systems. Options such as Direct-to-Chip cooling provide a strong balance of thermal performance, serviceability, and system compatibility, especially when supported by DOWFROST™ LC.
 

Direct-to-Chip Cooling for High-Density Infrastructure

Direct-to-Chip systems pump coolant through cold plates on CPUs or GPUs, transferring heat into the fluid. The heat then moves to a secondary loop connected to a cooling distribution unit (CDU).
This approach is especially relevant for high-density racks, allowing heat to be removed close to the source while supporting modular scalability, reduced floor-space requirements, and easier maintenance.
 

Why Use DOWFROST™ LC in Data Center Cooling?

The heat transfer fluid in a liquid cooling loop is central to system reliability, corrosion resistance, freeze protection, serviceability, and long-term performance.
Using the right heat transfer fluid is essential for mission-critical cooling systems. DOWFROST™ LC 25 is formulated for Direct-to-Chip, in-rack, and close-coupled cooling systems, ensuring reliable heat transfer while protecting against corrosion, fluid breakdown, biofouling, scaling, and freeze-related issues.

These two DOWFROST™ LC solutions enable system designers and operators to select the best fit based on operating environment, freeze-protection requirements, and cooling system design.

Applications in Data Center Infrastructure

DOWFROST™ LC is ideal for data center liquid-cooling applications that require a propylene glycol-based, corrosion-inhibited heat-transfer fluid specifically designed for these demanding environments.
Supported system applications include:

DOWFROST™ vs. DOWFROST™ LC

• Direct-to-Chip cooling
• In-rack closed-loop cooling
• In-row close-coupled cooling
• Cooling systems using CDUs
• High-density server rack cooling
• AI and GPU data center cooling
• Retrofit and new-build liquid cooling systems

DOWFROST™ LC is not suitable for immersion cooling. Its optimal use is in Direct-to-Chip and rack-level closed-loop cooling—the core systems it is engineered to support.

DOWFROST™ vs. DOWFROST™ LC

The DOWFROST™ product family contains propylene glycol-based heat transfer fluids for closed-loop and secondary cooling. DOWFROST™ and DOWFROST™ HD provide freeze and burst protection across diverse markets.
For data center cooling, focus on DOWFROST™ LC, which is specifically designed for Direct-to-Chip and rack-level cooling systems, setting it apart from other products in the DOWFROST™ range.

Supporting Reliable Data Center Liquid Cooling Systems

Data centers require cooling systems that can support high-density computing without compromising uptime or long-term system reliability. Direct-to-Chip and rack-level liquid cooling provide a practical route for managing heat at the source, especially in environments driven by demand for AI, GPUs, and edge computing.
DOWFROST™ LC supports these systems with engineered, inhibited, propylene glycol-based heat-transfer performance, providing corrosion protection, freeze and burst protection, biostability, leak-detection support, and long fluid life. It is a purpose-built option for Direct-to-Chip and rack-level cooling systems in new or retrofit data center infrastructures.
