COOLING REINVENTED
The Future of High-Density Thermal Management
Unprecedented energy efficiency for mission-critical infrastructure.
WHY INCUMBENTS ARE STUCK
Two constraints: power and water
Global data-center power demand is climbing steeply, and cooling is a large share of it. Evaporative cooling is efficient but water-hungry; air cooling is dry but power-hungry. No legacy condenser class escapes the trade-off.
Water use
200–250M gal/year
Water a single 50 MW evaporative-cooled data center can consume.
Projected Demand
Projected rise in global data-center cooling-water use as AI capacity comes online.
+870%
MANDATE
Microsoft, Google, AWS and Meta pledges — Microsoft now deploying zero-water cooling.
Water positive by 2030
THE WHITE SPACE
Three condenser classes today — none solves both
AIR-COOLED
COP 3.0–3.5 — Limited by dry-bulb ambient
Reliable and water-free, but energy intensive during peak summer loads.
WATER-COOLED
COP 5.0–6.0 — High efficiency, high consumption
Excellent thermal performance, but consumes millions of gallons of water annually.
EVAPORATIVE
COP 4.0–5.0 — Hybrid trade-off complexity
Attempts to balance water and power but fails to excel at either in density.
Infrastructure planners have long been forced to choose between wasting precious water or consuming excessive power. In high-density AI environments, neither is a viable path forward.
Foggy Labs bridges this gap: reaching COP 8 without consuming a single drop of water.
A fourth class of condenser
Foggy: fog-cooled heat rejection
Patented technology that pairs the latent-heat efficiency of water with full moisture recovery — air-cooled simplicity, water-cooled performance, zero net water loss.
1 · Atomize
Water becomes fog Water is turned into fog — and is 100% recovered downstream.
Absorb latent heat
Latent-energy transfer Fog pulls heat via latent energy — far more efficient than sensible air cooling.
Recover & recycle
Closed loop A heat exchanger condenses the vapour back to liquid in a closed loop.

Foggy vs. the competition
Across both classes the major brands cluster together — Foggy is the outlier: zero water and the lowest PUE. Illustrative comparison for discussion; per-brand figures are representative.

FITS YOUR PLATFORMS
The integration path into existing OEMs
Foggy connects into the standard chiller / condenser architecture — replacing the heat-rejection stage, not the whole plant.
REPLACE THE COOLING TOWER
For water-cooled & evaporative systems
Eliminates the primary source of water consumption. Fog + air condenses the chiller’s hot refrigerant; moisture is recovered via a secondary exchanger. Zero net water — water-cooled performance kept.
DROP-IN STAGE
Keep the rest of the plant
The chiller, distribution and controls stay; Foggy swaps in at the heat-rejection stage, minimizing redesign and re-certification effort for your platform.
