PUE 1.1
Seawater cools better
Cooling with seawater instead of air or fresh water lowers a data center's PUE from 1.5 to 1.1: 80% less electricity dedicated to cooling. The physics is favorable.
Technology · Titech Free Cooling
Cooling with the sea, PUE 1.1.
The submerged titanium heat exchanger uses the sea as a thermal sink. It builds on our antifouling surface, which is what makes it durable.

The why
The sea is the best heat sink. Biofouling used to block it.
under 0.1%
Almost nobody used it
Marine growth ruined heat-exchanger transfer in weeks. That's why under 0.1% of installations use marine cooling today, despite being near the coast.
Solved
Our surface unlocks it
The anti-biofouling titanium exchanger stays clean without chemicals. What used to foul in weeks now lasts years.
How it works
A submerged titanium box cooler. A single circuit.
We remove the chiller, the cooling tower, the seawater pumps and the filtration. The submerged exchanger transfers heat directly to the ocean.
SYSTEM
Three components, one circuit
Submerged titanium box cooler + a single fresh-water pump + the existing CRAH units. Versus the 5 subsystems and 2 circuits of the conventional system.
SAVINGS
95% less cooling use
No compressor, no tower. Heat goes to the sea by convection. The electricity dedicated to cooling drops drastically.
WATER
Zero fresh-water use
With no evaporative towers there is no fresh-water evaporation. Zero direct water footprint in cooling.
REGULATION
Auditable EED/ESG lever
Data centers >500 kW report and cut electricity use since 2024 (EED). Titech Free Cooling is a documentable reduction, with no chemicals and no fresh water.
