As AI large models iterate at breakneck speed and server clusters keep scaling up, heat dissipation in high-density data centers has become a make-or-break challenge. Air cooling is hitting its physical limits, and immersion liquid cooling — with its superior heat-transfer efficiency — has become the mainstream route for AI infrastructure. Yet the cooling medium itself has become the industry's bottleneck: data centers and semiconductor test facilities across China have seen their immersion-cooling upgrades stalled by this single critical material.
The Imported Fluorinated Fluid Dilemma
For years, immersion cooling projects in China have relied heavily on imported fluorinated fluids, which come with two hard flaws: painfully long procurement cycles and high total cost of ownership — significantly inflating both the construction and ongoing O&M budgets of liquid-cooled facilities.
Meanwhile, some early domestic substitutes still show clear performance gaps:
Insufficient dielectric strength: Directly immersing energized hardware poses serious risks of leakage and short circuits.
Excessive viscosity: Poor fluidity weakens heat exchange; under heavy loads, chip temperatures fluctuate widely and thermal control becomes unstable.
Poor component compatibility: Long-term immersion of PCBs, connectors, and plastic components can cause swelling and corrosion, easily triggering hardware failures and server downtime.
Missing environmental compliance: Without international certifications such as RoHS and REACH, project commissioning and cross-border business compliance are both restricted.
Too expensive to use, too underperforming to trust — many companies are stuck in a dilemma: they want liquid cooling, but dare not use it, and cannot afford it. The market urgently needs a domestically produced immersion coolant that matches imported performance, offers a controllable supply chain, and meets compliance requirements.
BX-308 Immersion Coolant: A True Domestic Equivalent to Imported 3M Fluorinated Fluids
Addressing these pain points, BaoXing — a source manufacturer with deep expertise in specialty materials — launches the BX-308 series of immersion coolants, whose overall performance benchmarks against imported 3M fluorinated fluids, delivering genuine domestic substitution for this critical liquid-cooling medium.
Five Core Advantages: Safety, Performance, Cost, and Compliance — All Covered
✅ High dielectric insulation, protecting 24/7 compute equipment. Excellent dielectric properties allow direct immersion of energized electronic components, eliminating leakage and short-circuit risks at the source — a solid safety line for AI servers running around the clock at full load.
✅ Low-viscosity formulation for efficient, stable heat exchange. A low-viscosity molecular formulation delivers outstanding fluidity, rapidly carrying away heat generated by chips, motherboards, and connectors. Even at full server load, hardware temperatures stay stable — solving the thermal-control instability of high-compute scenarios.
✅ Strong material compatibility — no corrosion or swelling during long-term immersion. A specially modified base formulation is gentle on PCBs, chips, connectors, and plastic seals. Prolonged immersion causes no corrosion or swelling, reducing the probability of hardware damage and unplanned downtime, and extending equipment service life.
✅ Multiple authoritative certifications for environmental compliance at home and abroad. Certified to RoHS, REACH and other standards, with low-volatility eco-friendly characteristics — meeting commissioning requirements for domestic data centers and semiconductor lines, and aligning with overseas environmental audits for projects going global.
✅ Full supply-chain control from a source factory: lower cost plus stable delivery. With 20 years of R&D and mass-production depth in high-performance specialty materials, BaoXing fully controls formulation development and manufacturing in-house. Compared with imported fluorinated fluids, BX-308 significantly reduces procurement and operating costs, breaks free from long overseas lead times, and delivers stable, controllable supply — cutting the total cost of liquid-cooling construction and O&M.
Multi-Track Applications, Covering Data Centers and Semiconductors
BX-308 immersion coolant fits a wide range of industrial applications — compatible with both new liquid-cooling projects and fluid replacement in existing facilities:
