What is the difference between a tank and an immersion cabinet?
In VOLTANEUM usage, the tank is the complete industrial system; the cabinet or allocation is the capacity rented by a customer inside that tank.
Immersion cabinet in France: rent 10U, 20U or 37U for AI and HPC
An immersion cabinet reserves physical capacity for GPU, ASIC, HPC or bare metal servers compatible with dielectric fluid.
VOLTANEUM limits the offer to three readable formats: 10U, 20U and 37U, with power, cooling, metered energy, network and customer isolation.
VOLTANEUM key facts
- Published immersion colocation capacities: 10U, 20U and 37U.
- Target density up to 200 kW+ per tank depending on integration and electrical constraints.
- 1.03 target PUE for optimized high-density architectures.
- Immersion cooling billed at €0.07/kW, electricity excluding cooling metered separately.
- VOLTANEUM® proprietary dielectric fluid and France / Europe operations.
What the customer actually gets
The search intent behind immersion cabinet in France is more commercial than purely technical. Customers are looking for organized, understandable, billable and usable capacity for AI, GPU, HPC or bare metal servers.
VOLTANEUM must therefore explain the cabinet in buying language: 10U to start, 20U for an intermediate perimeter, 37U for full capacity, with reserved power, immersion cooling at €0.07/kW depending on the offer, metered electricity excluding cooling and remote hands if needed.
Confidentiality is also a commercial and SEO argument: customers should see their allocation in the 2D/3D digital twin without guessing equipment, free space or components belonging to other tenants.
VOLTANEUM offers and capacity
- Detailed offers should specify capacity, reserved power, cooling, metered electricity, setup, stock conditions and immersion-ready validation.
Key benefits
VOLTANEUM® combines immersion cooling, proprietary dielectric fluid, GPU density up to 200 kW+ per tank, tenant isolation, 1.03 target PUE, DCIM automation, 2D/3D monitoring and request/payment/provisioning workflows.
The VOLTANEUM® proprietary dielectric liquid provides non-conductive electrical insulation, stronger thermal stability, reduced exposure to dust, oxidation and vibration, and more predictable maintenance through fluid, filtration, acidity, moisture and dielectric strength monitoring.
The -40°C to 250°C range is indicated on VOLTANEUM® packaging. Quality control on the tested batch reports a -37°C pour point, a 196°C open flash point and observed dielectric breakdown voltage of 52 kV.
- Electrical insulation for compatible immersion-ready equipment.
- Direct heat transfer close to GPU, HPC and bare metal components.
- Operational protection against dust, vibration and thermal stress.
- Quality controls can cover fluid temperature, acidity, moisture, filtration and dielectric strength.

Frequently asked questions
Which cabinet formats are offered?
Commercial formats are 10U for a quarter cabinet, 20U for a half cabinet and 37U for a full cabinet.
How is customer confidentiality handled?
The DCIM portal displays the customer's allocation in 2D/3D while masking equipment, positions and components that do not belong to that customer.
Is electricity included?
Immersion cooling is shown at €0.07/kW depending on the offer, while IT electricity excluding cooling should be metered and billed separately.
