What is VOLTANEUM immersion cooling?
VOLTANEUM immersion cooling cools servers directly in a non-conductive dielectric fluid to increase density, reduce airflow, lower noise and stabilize AI/HPC workloads.
VOLTANEUM immersion cooling colocation offers
Immersion offers let customers rent a portion or full cabinet with dielectric cooling, reserved power and DCIM monitoring.
Customer hardware must be immersion-ready and validated before production.
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
VOLTANEUM immersion offers target workloads that quickly exceed classic rack limits: high-density GPUs, ASICs, intensive bare metal servers and HPC clusters. Each allocation combines U capacity, reserved power, immersion cooling at €0.07/kW and immersion-ready validation before installation.
Customers can rent a 10U quarter cabinet, 20U half cabinet or full 37U cabinet depending on actual demand. The goal is to sell usable infrastructure capacity, not only physical space: cooling, thermal monitoring, tenant isolation, energy, remote hands requests and the DCIM portal are part of the journey.

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
Is VOLTANEUM suitable for HPC and GPU workloads?
Yes. The platform targets GPU clusters, intensive computing, inference, fine-tuning, dense storage and environments where classic air-cooled racks become limiting.
How does a datacenter colocation offer work?
The customer selects an offer, country and available datacenter, then pays the initial fees. After validation, the allocation is provisioned and visible in the DCIM portal.
Can I rent a bare metal server without renting a cabinet?
Yes. Dedicated physical server offers let customers rent a bare metal server with operating system selection, remote management access and customer monitoring.
What is an immersion cooling cabinet?
An immersion cooling cabinet is physical capacity in a dielectric bath, allowing a customer to rent a portion or a full cabinet for GPUs, ASICs, HPC or immersion-ready servers.
Can I bring my own hardware?
Yes, in BYOH mode, subject to technical validation. For immersion, the hardware must be dielectric-fluid compatible and validated before installation.
