Immersion
Electronic components are fully submerged in a non-conductive dielectric fluid engineered for optimal thermodynamic properties.
The Science
Two-Phase Immersion Cooling —
Engineered for the Limits of Compute.
Single-phase and air cooling are legacy approaches. Two-phase immersion represents a phase change in thermal engineering itself — harnessing the latent heat of vaporization to achieve cooling performance that scales to terawatt compute.
The Process
How Entropy Cooling Works
Phase Change
As heat is generated, the fluid reaches its boiling point and vaporizes, drawing enormous amounts of latent heat directly from chip surfaces — far more efficiently than any convective method.
Recovery
Vapor rises to a condenser where it returns to liquid and cycles back into the bath. A closed-loop system with no fan energy, no water consumption.
Cooling Technology Comparison
How two-phase immersion compares across the metrics that matter.
| Metric | Two-Phase Immersion Entropy Method | Single-Phase Immersion | Air Cooling |
|---|---|---|---|
| Cooling Efficiency | Highest — latent heat transfer | High — convective transfer | Moderate — convective + fan |
| Max Power Density (kW/rack) | 100+ kW | 40–60 kW | 10–25 kW |
| Fluid Evaporation / Loss | Negligible (closed loop) | None | N/A |
| Noise Level | Silent | Near-silent | 70–85 dB |
| PUE Range | 1.02–1.05 | 1.05–1.10 | 1.3–1.6+ |
| Maintenance Complexity | Low | Low–Medium | High (filters, fans, ducts) |
| Water Consumption | Zero | Low | High (cooling towers) |
