Why use an immersion cooling datacenter?
Because GPU, AI, HPC and high-density bare metal workloads generate significant heat in limited space. Immersion cooling captures that heat directly at compatible hardware contact.
Immersion cooling datacenter in France: high-density infrastructure for AI and GPU
An immersion cooling datacenter answers a simple constraint: AI, GPU, HPC and bare metal workloads concentrate more heat than classic air-cooled racks comfortably handle.
VOLTANEUM structures that demand through a French and European platform combining immersion tanks, dielectric fluid, high-density colocation, GPU hosting, Cloud VPS, physical servers and a customer DCIM portal.
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 combination of datacenter, immersion cooling, GPU server, VPS and bare metal should be explained as an infrastructure chain. The buyer is not only searching for a keyword: they need usable, localized, monitored capacity aligned with power constraints.
VOLTANEUM can capture these intents by showing the full path: Cloud VPS for classic workloads, OpenStack for provisioning, GPU server or GPU Cloud for AI, bare metal for strong isolation, then immersion cabinet or high-density colocation when thermal constraints become central.
Premium content must stay credible: dielectric fluid, CDU, thermal loop, monitoring, reserved power, cooling cost, metered electricity, lead time and support are stronger than generic performance claims.
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
How is it different from a classic datacenter?
A classic datacenter depends heavily on airflow, fans and room cooling. Immersion cooling shifts the constraint toward the fluid, exchanger, CDU and thermal loop.
Which services does VOLTANEUM connect to this infrastructure?
VOLTANEUM connects immersion colocation, 10U/20U/37U cabinet capacity, GPU hosting, physical servers, bare metal, Cloud VPS, OpenStack and the customer DCIM portal.
Is immersion cooling relevant to Cloud VPS?
The VPS remains a virtual machine. The benefit is the upgrade path: start with VPS, then move toward GPU, bare metal or immersion capacity when the workload grows.
