Single Phase Immersion Cooling Fluids
Single-phase immersion cooling is rapidly emerging as the next evolution in liquid cooling for data centers, especially as CPUs and GPUs with thermal design power (TDP) ratings approaching 1500 watts become the new standard. Unlike traditional air-cooling or even direct-to-chip (DTC) liquid solutions, single-phase immersion provides superior thermal efficiency without the complexity and risks associated with two-phase cooling systems.
Benefits of Immersion Cooling for all Data Centers
For existing data centers and crypto-mining facilities that have an air-cooled infrastructure already in place, the benefits to converting to immersion cooling are:
Immersion cooling not only improves energy efficiency but also enables exceptional power usage effectiveness (PUE), freeing up electricity once allocated to air cooling for AI workloads instead.
Facilities can reduce labor requirements by eliminating dust accumulation, preventing component oxidation, and minimizing mechanical vibration, all of which contribute to hardware wear and failure
By ensuring consistent operating temperatures and avoiding frequent heating and cooling cycles, single–phase immersion cooling helps prevent thermal stress, leading to longer–lasting and more reliable hardware performance,
By ensuring consistent operating temperatures and avoiding frequent heating and cooling cycles, single–phase immersion cooling helps prevent thermal stress, leading to longer–lasting and more reliable hardware performance,
Single-phase immersion cooling reduces ambient noise (<55 dBA), power usage, and water usage for improved community acceptance.
Eliminating your facility’s dependency on water–intensive evaporative cooling significantly reduces water consumption and improves sustainability metrics under tightening European regulatory pressures.
