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.
Dedicated physical servers without colocation complexity
Customers who do not want to rent cabinet space can order a dedicated physical server directly.
Orders can include operating system selection, remote management access and connection details after provisioning.
What the customer actually gets
Physical server offers address customers who want to rent bare metal without subscribing to a full cabinet. Operating system selection, remote management options and related costs are integrated into the order flow.
When hardware is not in stock in the requested datacenter, the order can still be accepted and moved to a waitlist with an estimated lead time. This keeps the commercial request open while setting clear expectations.

Key benefits
VOLTANEUM™ combines immersion cooling, proprietary dielectric fluid, GPU density, 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.
