42U immersion tanks and coolant distribution units form one node: the same payload that deploys across an open floor or ships inside a 40 ft ISO container. Every ZEC facility, from a single sovereign node to 50 MW, is that block, repeated.
Air cooling fails at modern GPU rack densities. ZEC servers run fully immersed in single-phase dielectric coolant inside sealed 42U tanks, with heat rejected through dry coolers in a closed loop.
No cooling towers. No chillers. No evaporative water use. The loop stays sealed in operation, and cooling power drops 60 to 70 percent against air-cooled equivalents.
Design PUE is 1.02 against an industry norm of 1.4 to 1.6, with methodology available to qualified parties under NDA.
| Metric | ZEC SLIC | Legacy Air |
|---|---|---|
| Power Usage Effectiveness | 1.02 design | 1.4 – 1.6 |
| Evaporative water use | None | Millions of gallons / yr |
| Cooling power | 60 – 70% less | Baseline |
| Heat rejection | Closed-loop dry coolers | Towers, chillers, water |
| Deployment timeline | 8 – 10 months | 3 – 7 years |
Standardization is the speed. The same engineered block delivers as a pad-mounted node, a containerized unit, or an open-floor array like the ZEC Node 400.
ZEC facilities retrofit into warehouses, vacant retail, hospitals, universities and other existing commercial buildings with power in place: no land acquisition, no greenfield build, no multi-year interconnection queue.
Sites are selected behind interconnections already energized, and facilities sit below the 70 MW system-study threshold, which keeps projects outside the review cycles that stall hyperscale builds for years.
The result: signature to serving workloads in 8 to 10 months.
A disciplined, repeatable delivery sequence. Because the block is standardized, the schedule is too.
Existing building identified against pre-screened power availability; interconnection verified as energized.
Ownership or offtake executed before construction capital is committed. Capacity is never built on hope.
Node blocks installed, coolant loop sealed, hardware immersed and burned in on compressed timelines.
ZeroEdge manages the facility end to end: monitoring, maintenance, capacity management and reporting.
