What Is Dew Point Control?_
In liquid cooling deployments, dew point control uses environmental sensors to calculate the temperature at which moisture will condense and then enforces a safe margin for coolant supply. This protects electrical components from corrosion or shorts caused by unintended water formation. Control is typically achieved by adjusting chiller output or adding trim heat in the secondary loop.
Technical Details
Sensors measure air temperature and relative humidity at rack inlet and exhaust locations to derive local dew point. Coolant temperature is regulated via valves or variable-speed pumps in the coolant distribution unit. When facility chilled-water temperature drops below the calculated threshold, mixing valves or bypass loops raise the supply temperature to the cold plates.
How Leviathan Systems Works with Dew Point Control
Field crews confirm dew point margins during pre-commissioning checks on liquid-cooled racks before energizing GPUs. Verification occurs after manifold leak tests and before structured cabling and networking bring-up.
