iXora revolutionizes immersion cooling with its innovative closed-circuit design, seamlessly integrating into standard 19-inch server racks for effortless adoption. Unlike traditional immersion systems that rely on bulky open tanks or specialized enclosures, iXora offers a sleek, cost-efficient solution tailored for modern data centers, enabling unparalleled performance without the hassle of major infrastructure changes
Immersion cooling fully submerges IT hardware in a dielectric liquid, cooling all components uniformly with minimal infrastructure and no need for complex tubing or precise interfaces. In contrast, liquid cooling relies on intricate systems of pumps, pipes, and heat sinks to target specific components, making it more technically complex and leaving other parts dependent on air cooling
The great advantage of immersion cooling over liquid/on-chip cooling is its ability to cool all components of IT equipment uniformly by submerging them entirely in a dielectric fluid, eliminating the need for complex tubing, pumps, and specific contact points. This simplifies system design, reduces maintenance, and avoids hotspots that can occur with targeted on-chip cooling
immersion cooling is the most efficient way of cooling IT equipment because it allows direct heat transfer to a dielectric liquid, significantly reducing energy losses and eliminating the need for power-intensive air movement or secondary heat transfer systems. This efficiency makes it superior in terms of thermal performance, energy savings, and equipment density optimization.
Immersion cooling for IT systems is not yet common primarily due to its incompatibility with traditional server form factors and the significant infrastructure changes required for deployment. Existing immersion cooling solutions often involve non-standard tanks or enclosures, making retrofitting into conventional data centers expensive and logistically challenging, which slows widespread adoption movement or secondary heat transfer systems. This efficiency makes it superior in terms of thermal performance, energy savings, and equipment density optimization.

As always, the specifics depend on the system’s location, local electricity and water rates, the energy consumption of the servers, and whether the system is installed in a private data center or a colocation data center with different pricing structures. Independent research has shown that assuming a new data center is built specifically for immersion cooling using iXora’s HRM system, the CAPEX and OPEX will be more cost-effective from day one compared to a newly built air-cooled data center designed for the same number of servers. The ROI of 2 to 4 years is common but varies depending on the situation, and we are happy to discuss this further.

You instantly lower your carbon footprint using our HRM, since Data centers require far less energy and water compared to air-cooled solutions. Basically you can use your Kw twice.
Since there is no need for fans, your servers will use 25 ~ 35% less energy. Since the data suite will not heat up, no Data Center airco is required, saving another 20 ~ 30%.
A newly built data center or data suite could save up to 60% electricity using iXora’s HRM.
Our system operates with relatively high temperatures, allowing the use of a closed cooling system where water circulates exclusively through dry cooler systems, ensuring there is no water consumption as no evaporation occurs, unlike with cooling towers. Hybrid dry coolers, which utilize evaporative cooling techniques, can be employed in regions with higher ambient temperatures or during exceptionally hot periods in the summer. While this increases water consumption, it will still be 35 to 90 times lower compared to traditional cooling tower systems.
First of all, multiple fluids are possible and we’re looking for the one with the lowest impact. For now, our preferred fluid is Compuzol, a residual product that inherently makes it more sustainable.
A supply and return cooling water connection to the rack is needed. The cooling water can be chilled water, but it can also be warm water up to 40°C, depending on the workload and configuration of the server systems. Depending on the power consumption of the servers and the resulting heat generation, up to 10 liters per minute of chilled cooling water may be required for the most intensive workloads.
Common cooling water used in data centers is sufficient. Typically, this is clean tap water, or tap water with glycol, where possible softeners or other water treatment methods have been applied.
The management system includes options to view the current status of the system, such as temperatures, fluid levels, and any alarms. Sensor data can be easily accessed and integrated into external monitoring systems.
The system is accessible via a serial connection over the USB port. In the future, this will be available through a network connection.
We have scripts and tools available to easily extract data from the system, which can then be used to create dashboards in tools like Grafana. iXora also provides dashboard templates for Grafana.
Yes, the dieletric liquid is classification H332 and H304, it should not be swallowed or entering an airway.
If you remove the lid with the compute from the cassette, oil will naturally come along. By placing a container next to it, there is almost no leakage or waste, and you can do it in a separate area.
It’s a single phase, dielectric fluid, a residual product contributing to sustainability.
All E-ATX or smaller motherboards fit with all the regular compute parts.
Normally a single server fits in a HRM-4 immersion cooling cassette with up to 4 cassettes in a HRM-4 Chassis
Full-height & full-length (FHFL) dual-slot PCIe card such as the Nvidia H100 PCIE.
1 chassis with 4 cassettes is: 950mm * 19” * 13U (950 * 486 * 577 mm).
No, the iXora HRM solution does not require a CDU (Coolant Distribution Unit). Our design utilizes a direct connection to your facility’s cooling water system, ensuring a simple and efficient setup. This eliminates the need for additional infrastructure, reducing complexity, electricity and costs.
An empty chassis is ~45kg. A cassette is ~8 kg and the lid ~6 kg. Total ~101kg excluding the compute that is variable but ~45kg.
For PPE in our solution, gloves that provide protection against oil are recommended when server components need to be handled. Disposable nitrile gloves are a suitable option. Safety glasses can offer eye protection against splashes, although a pair of glasses is not necessary during normal use, as the fluid is removed from the cassette before the immersion cooling cassette is opened.
The system itself uses only about 10 watts. Through a redundant power connection, two industrial PSUs are used to supply power to the integrated management system.
Each cassette can provide up to 4 kW of cooling capacity when sufficient chilled cooling water is used. In total, an HRM-4 chassis can provide up to 16 kW of cooling capacity.
