Immersion cooling

Our GPUs are immersed in fluid, not air

The servers are immersed in a dielectric fluid, which does not conduct electricity. Heat is captured directly on each component, then carried away by a heat exchanger.

Immersion is the core business of VOLTANEUM by ITNET Technologies, part of the same group as Wayhost. VOLTANEUM designs and integrates the immersion tanks, the dielectric fluid, the heat exchangers (CDUs) and the container modules, operated in France and across Europe.

A high-performance solution for your AI workloads

The principle of immersion cooling, applied to your GPUs

01

Steady temperatures

The fluid captures heat right at the components, which helps GPUs keep a steady temperature during long computations.

02

Better heat transfer

A liquid carries heat far more efficiently than air: that is the very principle of liquid cooling.

03

Sheltered components

Once immersed, components are no longer exposed to dust or ambient air.

04

A calmer environment

Less dust, noise and vibration, and fewer hot spots around the servers.

Rejection or reuse

The heat, concentrated in the fluid, can be rejected or reused (water loop, heating) depending on the site.

OpenAI-compatible AI API

Add AI to your application in a few lines

Keep your OpenAI API-compatible tools: OpenAI SDK, Open WebUI, LibreChat, n8n… Just set the Wayhost API address and your key. Each request is charged per token against your prepaid credit.

from openai import OpenAI

client = OpenAI(
    base_url="API_BASE_URL",
    api_key="YOUR_KEY",
)
r = client.chat.completions.create(
    model="MODEL_ID",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(r.choices[0].message.content)

More than a graphics card: infrastructure you can trust

Your computations are processed in France, and your AI API requests are never used to train models.
