451 Research Report on Submer Immersion Cooling

We are delighted to share with you that 451 Research has published an impact report about Submer and our Immersion Cooling solution.

The Timing is Right

According to 451 “The timing is right: Technology and market conditions have never been more favorable for the adoption of liquid cooling” and “Submer has engineered a high-performing yet cost effective product.”

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.

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:

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 “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:

Data center liquid immersion cooling with adiabatic cooling towers

data center cooling

What is Adiabatic Cooling?

Adiabatic cooling is the process of reducing heat through a change in air pressure caused by volume expansion. In nature, adiabatic cooling is often associated with elevation. As seen with cloud formations, an air mass that is heated expands and becomes less dense. Being less dense, it is lighter and rises above a higher-pressure air mass. Having reached areas with less dense air, it further expands, losing energy that was gained, and cooling as it does so. When the cooling air crosses the dew point, moisture in the air accumulates as clouds. With enough moisture and cooling comes precipitation. The principles of adiabatic cooling are also applied to increase humidity in facilities.

What are Adiabatic Cooling Towers and why are they used in Data Centers?

Data center effects on climate change

green data center immersion cooling submer

This is one of the most serious topics we’re going to talk about and one of the main reasons the Submer Team have put their heads together to substantially help reduce data center CO2 emissions.

The Uptime Institute states in their 2014 Data Center Industry Survey that average self-reported PUE‘s for 2014 stand at 1.7. For sure self-reported means that only data centers that are happy with their PUE have actually reported and other studies clearly indicate that most probably, most of the data centers around the globe are still way over the PUE 2.0 mark. This means that for each 1kW of IT load, another 1kW is needed just to make make it run (basically to keep it cool).
