Immersion cooling is the most sustainable form of liquid cooling:

• It reduces power and direct & indirect water consumption, therefore reducing CO2 emissions.
• It lets your infrastructure operate at higher temperatures, providing more free cooling time.
• Higher power density leads to less real estate needed.
• Immersion cooling fluid is non-toxic, biodegradable, GWP=0, and it can be recycled.
• It protects the hardware from degradating agents such as dust, moisture and vibrations, which plays in favor of its lifespan.

Immersion cooling is simple and therefore reliable. It takes care of 100% of the IT components, ensuring thermal stability. If you look at the overall TCO, from server to infrastructure, immersion cooling is more competitive. Your future-proofed cooling infrastructure will outlast several IT refresh cycles/generations, with no server vendor lock-in. Technology runway is ensured by latest developments.

Absolutely! Submer pods can take advantage of the existing cooling infrastructure or data.

If only air cooling is available, a local closed water loop is installed to release the heat into the room. Not the best option in terms of efficiency, but the easiest one in terms of capital investment if no water loop is available.

If a water cooling loop is available, whether it be chilled or warm water, just connect the immersion system to it. Or consider using the return water from your other water-cooled equipment, taking advantage of the ability to operate with higher water temperature.

For the most efficient operation and best experience, choose an immersion-born server amongst the many currently available, whether it be 19″, 21″, or OCP.

If you prefer to try with some of your existing servers, only not-sealed HDDs are not submersible. Other than that, a retrofitting process should be followed, mainly consisting of checking the material compatibility of the components, removing the fans, replacing the thermal paste by a compatible TIM – readily available in the market, protecting the labels and, in some cases, replacing the heat sinks by immersion-designed ones for best performance.

Submer’s products are designed to facilitate daily IT-related operations.

For a quick DIMM or power supply swap, the server just needs to be lifted to expose the target components. There is no need to deal with Thermal Interface Materials (TIMs).

For more elaborate operations, servers can be taken to a service room and easily dried off if preferred.​ Cabling-related operations are performed as you are accustomed to, thanks to our cable management features.

As for the fluid, expect scheduled checks to ensure it remains in perfect operating conditions. No fluid top-up or removal is required when extracting or inserting a few servers, or due to evaporation.

Submer offers comprehensive trainings and certifications to get your staff up to speed to safely operate your immersion-cooled datacenter.
