Direct to Chip Cooling
)
Direct-to-Chip cooling is designed for use in enterprise and hyperscale environments, making it ideal for retrofits and phased upgrades. Castrol ON and DC Cooling Solutions formulate, distribute and support direct-to-chip cooling fluids. By harnessing the natural biostatic characteristics of specific pharmaceutical grade low-toxicity glycols and augmenting them with proprietary inhibitors, Castrol ON have developed an industry leading D2C coolant which meets ASTM, OCP and industry standards.
Castrol ON PG 25 is optimized for direct liquid cooling, a method where the cooling fluid comes into direct contact with the CPU or GPU, significantly improving heat dissipation. The fluid provides proven heat transfer performance, helping to maintain optimal temperatures even under heavy computational loads, which is critical for modern data centres.
Castrol ON: DLC PG25 Key Characteristics
- Non-harmful propylene glycol (PG) fluid
- Offers extended protection against metal corrosion
- Compatible with wetted materials present in the cooling system
- Biostable formulation preventing bacterial growth during service
- Ready to use, does not need dilution with water
