Data Centre Cooling Solutions
Immersion cooling removes heat by submerging servers and electronic components directly in a non-conductive dielectric cooling fluid.
In single-phase immersion systems, the fluid absorbs heat from high-performance CPUs, GPUs and other components before transferring it through a heat exchanger to the wider cooling infrastructure.
The performance of the dielectric fluid is therefore fundamental to both cooling performance and hardware protection.
Fluid selection needs to balance effective heat transfer with electrical insulation, material compatibility and long-term stability.
DC Cooling Solutions supply Castrol ON Immersion Cooling Fluid DC 15 and DC 20, advanced single-phase dielectric coolants developed specifically for electrical and electronic cooling systems.
The Castrol ON immersion fluid range combines low viscosity and effective thermal performance with excellent dielectric properties, oxidative stability and material compatibility.
Key fluid benefits
The result is a dielectric cooling fluid designed to maintain thermal performance while helping protect sensitive electronic hardware throughout its operating life.
Castrol ON Immersion Cooling Fluid DC 15 is a synthetic-based single-phase dielectric coolant developed for electrical and electronic cooling applications.
Its combination of thermal performance, flow characteristics, dielectric strength and long-term stability makes it suitable for demanding immersion cooling environments.
Castrol ON Immersion Cooling Fluid DC 20 is a low-viscosity synthetic-based dielectric coolant engineered for efficient heat removal and reliable electrical insulation within single-phase immersion cooling systems.
It provides excellent thermal, dielectric and stability characteristics for high-performance computing applications.
Immersion cooling places the cooling fluid in direct contact with critical IT hardware.
That makes fluid quality, cleanliness and condition particularly important.
Contamination, degradation or the use of an unsuitable fluid can affect thermal performance, dielectric properties and compatibility with the materials inside the immersion system.
DC Cooling Solutions provide specialist support throughout the fluidlife cycle, including:
This enables fluid condition to be monitored and managed ratherthan simply assumed.
The properties of an immersion cooling fluid need to remain stable over extended periods of operation. DC Cooling Solutions can monitor key fluid characteristics and identify changes that could affect cooling performance or hardware protection.
Where corrective action is required, DCCS can provide the technical support, fluid management and remediation needed to help maintain reliable operation.
Immersion cooling does not operate in isolation.
Heat removed from immersed IT equipment ultimately needs to be transferred into the wider data centre cooling and heat rejection infrastructure.
