Maximum‑Safety Fluids for Use in Sensitive Environments

The favorable thermal properties of VISCOBASE® 11‑263 result in strong and reliable cooling performance. In the server test rig, heat removal relies entirely on pure natural convection, a particularly demanding operating mode that typically penalizes fluids with higher viscosity due to restricted flow and reduced heat transfer.

Under these challenging conditions, VISCOBASE® 11‑263 enables efficient fluid circulation and effective heat transport. As a result, maximum fluid temperatures remain consistently low, supporting stable operation and delivering efficient cooling of the IT equipment without the need for forced convection.

In the lubricants sector, ester fluids are widely used in applications such as fire‑resistant hydraulic fluids, owing to their favorable balance of low flammability and excellent performance characteristics.

For thermal management applications, the most critical property combination is a high flashpoint paired with low viscosity, a balance that becomes increasingly difficult to achieve at flashpoints above 200 °C.

VISCOBASE® 11‑263 meets stringent flashpoint requirements while maintaining low viscosity and delivering strong cooling performance.
