Cestoil’s documented range comprises formulated glycol-based fluids with corrosion-inhibitor chemistry for secondary technology cooling systems. Applications include coolant distribution units, single-phase cold plates and associated heat exchangers.

This category covers fluids circulating inside a closed cooling circuit. Dielectric immersion cooling is a separate application requiring different fluid qualification.

In a typical liquid-to-liquid arrangement, the technology fluid circulates from the coolant distribution unit through the equipment cooling loop and returns to the unit’s heat exchanger.

Heat transfers to the facility cooling circuit across the heat exchanger. The two fluid circuits remain separate, with their own material and equipment requirements.

Formulations and concentrations provide different fluid-property profiles. Review the thermal and hydraulic requirements together.

• Cooling architecture and equipment manufacturer’s fluid requirements
• Operating conditions, environmental exposure and freeze protection
• Wetted metals, seals, elastomers, plastics and joining materials
• Existing fluid, residual contamination and changeover procedures
• Commissioning measurements and acceptance criteria

Record fluid condition at commissioning and monitor it against maintenance criteria agreed for the selected grade and system. Observations include pH, conductivity, appearance and evidence of contamination or deposits.

Review fluid changes alongside operation and maintenance history. Confirm compatibility, flushing, filling and filtration requirements for the actual equipment.
