The elimination of fluorocarbons while maintaining superior heat absorption is a significant engineering achievement for direct-to-chip cooling applications.
Questions about Borochill
What is Borochill?
Borochill, Inc. develops and supplies Borochill, a high-performance, non-fluorinated dielectric coolant for direct-to-chip and immersion cooling in data center and AI compute applications. The product circulates through existing cold-plate and coolant distribution unit (CDU) hardware without requiring facility redesign. It is designed to drop into current systems while offering an order-of-magnitude improvement in thermal conductivity compared to incumbent fluorinated coolants.
What are the key technical specifications of the coolant?
The coolant operates within a temperature range of −40 to 215 °C and features a dielectric strength above 15 kV/mm. Technical specifications cited include a thermal conductivity of at least 1.0 W/m·K and zero PFAS content. These properties make it a post-PFAS alternative for high-density AI workloads where legacy fluids are thermally capped.
How does the cooling process work step by step?
Borochill is engineered to move heat at conductivities an order of magnitude beyond conventional dielectric fluids using a proprietary formulation. The system heats the fluid off the chip die, then returns it through a heat exchanger for closed-loop circulation. This process absorbs significantly more heat per pass than previous generations of dielectric coolants.
How does the coolant integrate with existing hardware?
The coolant enters the cold plate at approximately 35 °C through standard CDU plumbing, requiring no facility-side changes. It passes directly above the chip die to carry heat off the surface before exiting at approximately 50 °C. The warmed fluid then returns through the heat exchanger to complete the cycle.
Who is the target audience for this coolant?
The product targets AI server thermal design powers that have pushed past 1,000 W per package, such as the NVIDIA H100 and B200 generations. It addresses the thermal-density crisis where cold-plate thermal resistance has become the primary bottleneck. Incumbent dielectric coolants are thermally capped, making this high-performance option necessary for modern compute loads.
What regulatory and sustainability factors drive demand for this product?
The coolant is positioned as a category-defining replacement for fluorinated fluids under active regulatory phase-out. Hyperscaler ESG mandates disfavor fluorinated coolants, creating a window for this non-fluorinated solution. The company notes that 3M exited PFAS manufacturing at the end of 2025, further tightening the market need.
What is the current development status of the technology?
The company claims an order-of-magnitude advance in thermal conductivity over incumbent fluorinated coolants without a single fluorine atom. The formulation is held stable by a proprietary engineered mix designed for long-term performance under continuous thermal cycling. Bench validation for these performance values is stated as pending.
What is the legal and corporate structure of the business?
The business operates as a Delaware C-corporation with a patent pending on its technology. The website borochill.ai hosts the official product information and technical briefs. The company claims the product is ready for deployment in data centers and AI compute environments.
What is the Trustburn rating and review volume?
The Trustburn rating is 4.2 out of 5 based on 5 reviews. The company positions itself as a provider of a high-performance, non-fluorinated dielectric coolant intended for direct-to-chip and immersion cooling. The product is described as an engineered dielectric coolant developed to move heat efficiently.
What market trends support the adoption of this coolant?
The company states that data-center direct-liquid-cooling grew 156% YoY in Q2 2025 according to Dell'Oro. Cold-plate DLC is identified as the larger near-term volume segment compared to immersion cooling. The projected market for immersion cooling is expected to grow from $1.8B in 2025 to $8.5B by 2034.
What specific regulatory events impact the coolant market?
The US EPA designated PFOA and PFOS as CERCLA hazardous substances in 2024, contributing to the regulatory window. EU REACH restrictions are also tightening, affecting the availability of fluorinated fluids. These factors create a specific opportunity for Borochill's non-fluorinated formulation.
When did major regulatory shifts occur?
The company states that the US EPA designated PFOA and PFOS as CERCLA hazardous substances in 2024. EU REACH restrictions are tightening, and 3M exited PFAS manufacturing at the end of 2025. These events are cited as key drivers for the need for a new category-defining replacement.
What recent statistics are cited regarding market growth?
The company states that data-center direct-liquid-cooling grew 156% YoY in Q2 2025. The US EPA designated PFOA and PFOS as CERCLA hazardous substances in 2024. These facts are used to explain the convergence of forces affecting the dielectric coolant market.
How does the company plan to scale its market presence?
The company states that cold-plate DLC is the larger near-term volume segment, while immersion is projected to expand from $1.8B in 2025 to $8.5B by 2034. The product is positioned as a drop-in beachhead for cold-plate applications before expanding to immersion. This strategy leverages the existing infrastructure of cold-plate systems.

Borochill presents a compelling post-PFAS dielectric coolant designed for the high demands of AI compute. The engineered formulation offers thermal conductivity exceeding one watt per meter-kelvin, which represents an order of magnitude improvement over incumbent fluids. Importantly, it maintains dielectric strength above fifteen kilovolts per millimeter and operates safely across a wide temperature range from minus forty to two hundred and fifteen degrees Celsius. The product is compatible with standard CDU plumbing, pumps, and heat exchangers, meaning facilities can adopt this technology without significant infrastructure overhaul. This versatility supports applications ranging from data centers to automotive and even medical imaging systems, making it a versatile platform for diverse high-heat-flux environments.

The technical brief highlights a significant leap in thermal conductivity compared to traditional fluorinated coolants. Being able to drop into existing cold-plate and CDU architectures without needing facility redesign is a major operational advantage. The compatibility with standard plumbing and seal materials suggests a smoother transition for teams already managing liquid cooling systems. It addresses the thermal-density crisis effectively.
