What Is Propylene Glycol Coolant?_

Propylene glycol coolant is a mixture of propylene glycol and water (typically deionized water) that circulates through liquid cooling systems to absorb heat from GPU modules and transport it to heat rejection equipment. It is preferred over ethylene glycol in many data center applications due to its lower toxicity, making it safer for personnel in case of leaks or maintenance. The coolant’s thermal properties, such as specific heat and viscosity, are selected per the system design to balance heat transfer efficiency with pump power requirements.

Technical Details

Propylene glycol concentration and the inhibitor package are formulation choices with different roles. The applicable coolant supplier and equipment manufacturer establish composition and material compatibility for the actual conditions. This term supplies no default blend, treatment interval, electrical-isolation guarantee or permission to use an aqueous fluid for direct-contact immersion.

How Leviathan Systems Works with Propylene Glycol Coolant

The customer and OEM appoint qualified parties for the applicable cooling-system work and its acceptance. Leviathan does not install, connect, test, commission or maintain liquid systems. Any separately agreed physical IT installation or cabling work retains its own authorized scope and handoff.
