ThermaSafe R

Best choice for immersion cooling

ThermaSafe R is an engineered dielectric coolant designed for high-density data center and immersion cooling applications, delivering stable and efficient thermal performance under demanding operating conditions. With an ultra-low viscosity of 5.1 cSt at 40°C, it ensures smooth circulation, reduced hydraulic resistance, and lower pumping energy consumption across large-scale systems. The fluid enables efficient convective heat transfer, supporting uniform temperature distribution and reliable operation in high heat flux environments. Based on ULTRAPURE™ PAO (Group IV) technology, it provides exceptional chemical stability and a service life of up to 10 years with minimal degradation. Its ultra-pure formulation contains no metals, sulphur, heteroatoms, or sediments, with water content maintained below 50 ppm, ensuring maximum hardware protection and long-term system cleanliness. Low foaming characteristics and stable flow behavior support consistent performance in immersion and closed-loop cooling systems. The fluid is non-toxic and biodegradable, allowing safe handling, operation, and disposal without special procedures. Low aromatic content (<1000 ppm) and high purity reduce oxidation risk and maintain consistent dielectric properties over time. The combination of thermal efficiency, chemical purity, and operational stability makes it suitable for scalable, high-reliability cooling infrastructure.
