Native immersion & DTC cooling environments
While legacy colocation sites struggle to cool modern GPUs, we deploy Immersion Baths (25kW–100kW) and Direct-to-Chip (DTC) environments built specifically for your high-density compute.
Transition ready
Start in air-cooled staging racks and move to liquid cooling whenever your hardware is ready.
Cost efficiency
By consolidating workloads into high-density pods, you cut space, power and operational expenses.
Proven reliability
Consistent thermal performance that protects GPUs and high-density hardware under sustained load.

Full-service management, zero friction
We provide a full service wrap by default.
Immersion Cooling
Immersion cooling gives you the ability to run dense GPU and AI workloads without the thermal limits of traditional air-cooled racks. Your hardware is submerged in a dielectric fluid that transfers heat far more efficiently, allowing sustained performance at higher power levels.
Direct to Chip (DTC) cooling
Direct-to-Chip cooling delivers liquid directly to the processor and GPU cold plates, allowing you to run high-power workloads with precision thermal control. Instead of relying on airflow, heat is removed at the source, enabling dense compute environments to operate more efficiently and more predictably.
Secure cages and halls
Secure cages and private halls give you dedicated space built around your operational, compliance and security needs. Whether you need a single locked cage or a fully customised hall, these environments provide controlled access, resilient power and cooling, and full isolation from neighbouring tenants.
A pricing model that rewards density
We charge for power, not real estate. The more efficient your deployment, the more cost-effective your colocation.

Built for the next generation of compute
We at Carbon-Z focus on continuous improvement of our Data Centres, constantly looking at making improvements to energy efficiency, reduction of power costs and better network connectivity.
We also recognise that deployment of environments where customers require them is also key, so we have adopted a build on demand model to accommodate fast and agile deployment of fit for purpose highly sustainable micro data centres within our existing commercial property footprint.
Frequently Asked Questions
Colocation allows businesses to house their own servers and infrastructure within a professionally managed data centre. It is suitable for organisations that need reliable power, cooling and connectivity without building and maintaining their own facility.
Our environments are designed to support a wide range of workloads, including enterprise IT systems, cloud platforms, AI training, GPU clusters and high-performance computing applications.
If your infrastructure runs at higher power levels or includes GPU-based workloads, high-density environments may be more suitable. Standard colocation is typically used for lower-power enterprise and networking systems.
Yes, deployments can start in air-cooled environments and move into Direct-to-Chip or immersion cooling as your hardware requirements increase.
We charge based on power consumption rather than physical rack space, allowing you to optimise costs by increasing the efficiency and density of your deployment.
Our facilities provide on-site technical support, including smart hands services for tasks such as reboots, hardware checks and basic maintenance, alongside 24/7 monitoring and security.
