EV Cooling Fluids
Synthetic ester dielectric ester base oil
We are experts in the manufacture of low viscosity Group V ester base oils. We offer dielectric base oils to create cooling fluids for safe and effective immersion cooled electric vehicle battery modules.
Our dielectric product offering is marketed under the Priolube™ EF brand representing high-quality, high-performance base oils designed for the formulation of cooling fluid formulations specifically designed for electric vehicles.
Direct immersion cooling using dielectric fluids in electric vehicles
Driven by the need to electrify, the automotive sector is now focused on creating highly efficient, power dense and lightweight electric motors, batteries and power electronics. Effective thermal management is now the key challenge to overcome in unlocking maximum performance. Battery capacities are increasing and consumers desire even faster charging rates, increasing heat output which must be managed.
