Cool electronics more efficiently and safely. Synano’s dielectric oils deliver the highest heat transfer with superior electrical insulation.
Synano Oil Series fluids are engineered for single-phase immersion cooling:
a highly efficient approach to thermal management where servers, batteries or power electronics are directly submerged in a non-conductive synthetic fluid.
By infusing dielectric oils with nanoparticles, we achieve unprecedented cooling efficiency while also increasing electrical insulation and maintaining material compatibility. The result: you can run your equipment harder, eliminate hotspots, and extend component lifetimes under either natural or forced convection.







Removes heat faster delivering up to 20% higher cooling efficiency than conventional dielectric oils.
Exceptional dielectric strength with up to 2× higher breakdown voltage than conventional fluids.
Fully compatible with hardware materials (metals, plastics, PCB coatings), with no damage or swelling.
Non-toxic, safe and chemically stable,
safe for long-term operation without degradation.
Custom made fluid formulations optimized to meet your exact performance and system requirements.
[ Products ]
Synano offers two categories of dielectric oil solutions:
Tailored additives to boost your existing base oil, or as ready-to-use dielectric oils.
Custom formulations to enhance your immersion oil.
We work with your base oil and develop an additive tuned for viscosity, dielectric strength, flash point, and thermal conductivity, meeting your exact system requirements.
Our best dielectric oil for immersion cooling, loaded with nano-additives (Synano NanoOil™). Delivers up to 20% better heat transfer to existing immersion setups without hardware changes and plug-and-play installation.
