Electronic Thermal Fluids
Immersion
Immersion cooling is one of the most advanced thermal management technologies available for modern electronics and data centers. Servers, graphics processing units (GPUs) that power artificial intelligence (AI) and high-performance computing, application-specific integrated circuits (ASICs) used in specialized computing applications, and other electronic components are fully submerged in a dielectric fluid that safely removes heat while overcoming many of the limitations of traditional air cooling.
Soltex Opticool® CM, HE, DC, and PE fluids are engineered for single-phase immersion cooling applications. These dielectric fluids combine strong electrical insulation with excellent thermal performance, enabling direct contact with energized electronics while maintaining safe and reliable operation.
