Opticool Fluid®

Soltex's Opticool Fluid® is an ultra-low-viscosity dielectric heat transfer fluid. It has excellent cooling performance. It’s made from highly purified synthetic hydrocarbon oils and advanced antioxidants. Opticool® is compatible with other hydrocarbon oils and standard equipment materials. Opticool® is widely used as a cooling fluid in high voltage electronic equipment and to cool electronic circuit boards. The viscosity of Opticool Fluid® is below that of standard mineral transformer oil. Tests and field experience show that equipment designed to operate with standard transformer oil will often operate at lower temperatures when filled with Opticool®. Opticool Fluid® is non-corrosive and not hazardous to workers. It can be stored, handled and processed in the same way as standard mineral oils. Opticool Fluid® pours at temperatures down to -50 C. It’s ideal for applications in cold environments. Being synthetic, Opticool® contains no sulfur at all.
