What Is Cooling Tower?_
A cooling tower uses evaporation to transfer heat from the facility water loop to the atmosphere, typically as part of a condenser water system. In liquid-cooled GPU deployments, it rejects the heat captured by coolant distribution units (CDUs) from the rack-level liquid cooling loops. The tower's performance depends on ambient wet-bulb temperature and requires regular maintenance to prevent scaling, biological growth, and drift.
Technical Details
Cooling towers operate by spraying warm water over fill media while fans draw air through the structure, promoting evaporative cooling. The cooled water returns to the facility loop, often via a heat exchanger or directly to CDUs in direct-to-chip or immersion systems. Water treatment is critical to control corrosion, fouling, and Legionella bacteria, with blowdown and chemical dosing managed according to manufacturer specifications.
How Leviathan Systems Works with Cooling Tower
During site commissioning, Leviathan Systems verifies cooling tower flow rates, fan operation, and water quality before connecting the facility loop to rack CDUs. We also coordinate with facility teams on tower placement to avoid recirculation and ensure adequate makeup water supply.
