Earth Day

April 22nd is an increasingly important date internationally and especially important for us here at Submer Technologies. Why? Because it happens to be Earth Day. Our entire raison d’être has to do with supporting technological progress with minimum possible impact on our wonderful planet, Earth.

Earth Day has been celebrated since 1970, the year in which senator Gaylord Nelson first encouraged American students to discuss and generate awareness around environmental issues. A mere 45 years later, Submer was born, a tech-company that concerns itself with helping data centre owner/operators, crypto miners, AI, 3D rendering and edge computing innovators progress without wasting precious resources (such as energy and water), while running a viable competitive business.

The Very Hungry Datacenter

Datacenters today consume more electricity than all of India.

According to the article “Much work needed to make digital environmentally sustainable economy” published in February 2018 by The Guardian, datacenters consume more than 6% of the world’s electricity, (more than the entire country of India) and they produce 2% of the world’s carbon emissions (almost as much as the airline industry).

Submer Immersion Cooling Lift-Off!

It’s all systems go at Submer Technologies since the beginning of March 2018. The revolutionary Barcelona based Immersion Cooling Company has successfully emerged from the pre-launch phase and is now ready and poised for prime time, to bring immersion cooling to hosters, cloud providers, regular datacenters, edge computing, cryptocurrency mining, blockchain and research datacenters.

Looking from the outside in, it may seem that things have been a bit quiet over the last months here at Submer, but let me assure you, that is definitely not the case! We have been busy with R&D, putting the best possible team together, ramping up our production, certification, all in all getting ready for big-time, which is coming right now.

With Immersion Cooling, our mission is to enable edge computing outside of the traditional datacenter, make datacenters more modular, compact, eco-friendly and highly efficient.

Immersion Cooling Leveraging Social Responsible Data Centers

data center efficiency

Welcome to the wave of the “socially responsible” data center, or not. The bottom line from the NGO Natural Resources Defense Council (NRDC) paper is that nearly half of the data centers do not define energy efficiency objectives. They don’t even have an energy efficiency plan in place.

One of the references analysed is the survey conducted by Digital Realty Trust in January 2013 which concluded that only 20% of the 300 North American data center companies with revenues of at least $1 billion and/or more than 5,000 employees have a PUE below 2.0, with the average at 2.9.

The main recommended actions coming from this paper to the medium-large data center are basically the following:

Will Data Centers implement Immersion Cooling?



Since the 1960’s, supercomputers have been cooled with liquid. Some extreme density supercomputers such as the Cray-2 (released in 1985) and Cray T90 (released in 1995) used large liquid-to-chilled liquid heat exchangers and single or two-phase immersion cooling oils for heat removal.

Most of the supercomputer manufacturers have used, use or are trying to use immersion cooling. But what’s holding back on getting Immersion Cooling into the data center to cool commodity hardware? In our opinion, cost and comfort.

Microsoft testing undersea immersion cooling


Could the future of the data center be under the sea? Microsoft sure seems to think so! Project Natick is a research project run by Microsoft to evaluate the possibilities of cooling servers under water and in the future, even generating power to run those servers thanks to waves, tides or sea wind turbines.

Not much has been disclosed about Project Natick, but here are some facts:

Introducing the best open-bath Immersion Cooling solution ever built

Submer Pod Render - FullHD

Final sign-off from our engineers has finally moved the Submer “Phase 1” Pod from an idea in our minds to something tangible. Manufacturing is heavily underway with the full intent of keeping our Feb-March timeline for the Pod deployment at the BitNAP data center.

The Submer Immersion Cooling Prototype is a full-size fully functional system. Its designed to heavily test and demo that everything we’ve thought of and designed is actually feasible. It will also allow us to show the technology to potential early-adopters.

Not so obvious benefits of immersion cooling in your data center


Giving your servers a bath in an immersion cooling environment has some immediate benefits that we’d like to expose in this short article. There’s some obvious ones that we’ve mentioned many times like making your data center greener and slashing operation costs, but today we’re going to talk about some not so obvious benefits:

  • Silent Operation: this one is straight-forward. All fans on the servers are usually removed before placing them into their dielectric bath. Of course even if they had fans, by placing them in a fluid we’re immediately silencing them. It might not sound as a great benefit, but for those of us that’ve worked for hours in a row with servers inside a server room, we’ve felt the pain. Its very impressive to walk into a immersion cooling data center room with hundreds or thousands of kW’s of IT hardware submerged and not hear a thing. The dual pump system is just as silent, so you won’t be hearing them either.

Submer Immersion Cooling “Phase1” Pod under construction

Submer Pod Render - FullHD

The Submer immersion cooling Pod design for “Phase 1” is closed and its under construction! A very important milestone in the project to get the prototype installed in the BitNAP data center and start proving that Immersion Cooling is the data center cooling solution of the future.

As mentioned in previous posts, the Submer Pod structure has been fully designed from the bottom-up by our engineers and is being built by a Barcelona-based rack manufacturing company.

Submer immersion cooling “Phase 1” prototype moving ahead

As we quickly progress in closing the Submer immersion cooling prototype design and components with our engineers, we’ve also pinned down the exact location for the full-size functional prototype (codename “Phase 1“) inside the BitNAP data center.

As mentioned in one of our previous postsBitNAP has kindly provided us with a closed-off space inside one of their large server rooms. The location is perfect as its going to allow us to:
