FAQ

Frequent questions

Understanding the technology

Can electronics really run while immersed in a liquid?

Yes — provided the liquid is dielectric, i.e. electrically insulating. Components run normally, better cooled than in air: the liquid captures heat on direct contact, with no fans. The closed environment eliminates dust, humidity and vibration.

How is it different from direct liquid cooling (DLC / cold plates)?

DLC cools certain components (CPU/GPU) through cold plates while keeping air for the rest. Total immersion submerges the entire server in the bath: all the heat is captured by the liquid, with no residual air-handling chain.

Are my current servers compatible?

The architecture is vendor-agnostic, but compatibility is established equipment by equipment (dimensions, mass, power supply, firmware, fan removal): the status is "compatible", "conditional" or "not tested", never presumed. The IT inventory requested in the project journey serves precisely this purpose.

Is the fluid hazardous or polluting?

No. The iICE Liquid fluid is a proprietary dielectric that is 100% biodegradable, harmless to both electronics and the environment. Its safety data sheet is supplied with every delivery; handling, containment, regeneration and recycling are part of the installation requirements and of Immersion Infinite services.

Preparing a project

Can my building host immersed racks?

The points of attention are floor load (an immersed rack is heavier than an air-cooled rack), access routes (doors, corridors, lifts) and hydraulic connection. The "Start my project" journey collects this data; above certain thresholds, a structural study is requested rather than presumed.

What happens to the heat produced?

It is available in a liquid loop, easier to reuse than lukewarm air: building heating, district network, industrial process. The real potential depends on the target temperature, the distance to the off-taker and seasonality — every case gets a local study.

Does the pre-qualification summary commit me?

No. It is explicitly non-contractual: it lists your inputs, the assumptions, the candidate product families and the data to be confirmed. It only becomes a study dossier after review by an Immersion Infinite engineer.

What do you do with my data?

Minimisation: every field has an explained purpose; the draft stays on your device until submission. After transmission, the data is used solely to process the case, with rights of access, rectification and erasure. Details are in the trust section.

Do you offer an availability guarantee (Tier)?

Availability concerns the site's full topology (power, loops, pumps, operations), not just cooling. We qualify the points of failure in the project journey and claim no Tier level without formal validation by Uptime Institute.

Glossary

The essential terms

Definitions are available in context throughout the site (dotted-underlined terms).

Total dielectric immersion: Cooling of electronics by complete immersion in an electrically insulating (dielectric) liquid. Heat is captured on direct contact with the components, with no cold-air circulation.
iDTM: Immersion Infinite's range of dielectric immersion systems for server thermal management — from the 19-inch rack to the container.
PUE — Power Usage Effectiveness: Total site energy divided by the energy consumed by IT. A PUE of 1.0 would mean all energy serves compute. The "mechanical share" refers to cooling's contribution to this ratio.
WUE — Water Usage Effectiveness: Litres of water consumed per kilowatt-hour of IT energy. Evaporative cooling has a high WUE; a closed loop targets zero WUE.
kW/U — kilowatt per rack unit: Power density per unit of rack height (1U = 44.45 mm). Dense AI servers exceed the capabilities of conventional air cooling.
MSS — System supervision module: Rack-mounted embedded-intelligence module that drives thermal regulation and pushes telemetry, physically isolated from the IT load to reduce the attack surface.
DLC — Direct Liquid Cooling: Partial liquid cooling via cold plates on the hottest components, with air still required for the rest of the server.
Building-block: Modular design principle: each module is installed, moved or replaced independently, without immobilising the whole (hot-swap).
PMMA: Polymethyl methacrylate — the transparent, lightweight material of iDTM tanks, paired with an aluminium frame.
Waste heat: Heat produced by a process (here, compute) and usually lost. Recoverable for a building, a district network or an industrial process.
Edge: Computing deployed as close as possible to its use (industrial site, antenna, branch office), as opposed to large regional centers.
OCP — Open Compute Project: Open standard for data center hardware, notably the 21-inch rack format.
SDS — Safety Data Sheet: Regulatory document describing the properties, hazards and handling of a chemical product, here the dielectric fluid.
Site Survey: Structured survey of a site's characteristics (structure, access, power, thermal, environment) that determines the feasibility of an installation.
RPO / RTO: Maximum tolerable data loss (RPO) and maximum tolerable downtime (RTO) after an incident.
I4DC™: The Immersion Infinite urban data center: any building becomes a data center — 1.2 t/m² of floor load and 2.70 m of ceiling height are enough, with no chillers or cooling towers.
