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.”

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.

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?
