CT-COOL Immersion Cooling Fluid
Single-phase immersion cooling fluid for data centers: food-grade purity, PFAS-free and low volatility, from our partner ACI (Advancing Chemistry Inc.).
CT-COOL immersion cooling fluid cools servers and other electrical equipment by transferring heat away from them far more effectively than air. Compared to energy-intensive air cooling, it reduces overall power consumption and energy costs, and protects equipment from overheating and failure.
Server performance: conducts heat better than air to remove the excess heat generated by equipment.
Reliability: helps keep equipment running smoothly with fewer breakdown interruptions.
Reduced energy usage: effective heat transfer lowers energy costs.
Safety: food-grade purity and PFAS-free (no intentionally added fluorocarbons), with low volatility and no contribution to global warming.
