Castrol is developing dielectric fluids for immersion cooling systems. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Founded in 1899, CC Wakefield & Co. Limited initially focused on producing lubricants for trains and heavy machinery. Over time, the company expanded its expertise to develop specialized lubricants for automobiles and airplane engines, incorporating castor oil - a plant-based oil derived from castor beans - to ensure performance under extreme temperature conditions. The product was called Castrol, and the company was later renamed after its famous creation.

One of its key focus areas is the development of advanced dielectric fluids for immersion cooling systems. This approach sees entire servers submerged in non-conductive fluids that absorb and transfer heat away from the components, eliminating the need for traditional fans.
The Castrol ON Liquid Cooling Centre of Excellence in Pangbourne, UK, serves as a state-of-the-art research and development hub for liquid cooling technologies. The facility develops customized solutions and rigorously tests fluid dynamics, material compatibility, and server performance, to address the challenges of traditional cooling methods.
Writer Jordan Ranous noted, “In one of the test cells, we observed GRC’s tank, which had a striking green glow due to the specific fluid Castrol was using. The servers submerged in this tank were undergoing compatibility and performance testing. Castrol ensures that every component, from CPUs to cables, can operate effectively in immersion cooling environments without degradation.”.
