FAQ

What is Immersion Cooling?

Also known as liquid submersion cooling, it is the practice of submerging computer components (or full servers) in a thermally, but not electrically conductive liquid (dielectric coolant).

1999

Is Immersion Cooling more efficient than air cooling?

Yes. As Immersion Cooling uses a thermally conductive liquid, it is ca. 1400 time more efficient than air cooling at transporting heat.

1999

What kind of liquid does Submer use?

Submer uses their own in-house developed synthetic dielectric fluid (SmartCoolant) which does not conduct electricty, but is extremely efficient at dissipating heat and protects hardware from dust/sand particles and from moisture.

1999

How often does the fluid (SmartCoolant) need to be changed?

With a lifespan of 15-20 years, Submer’s SmartCoolant is designed to see multiplegenerations of IT Hardware.

1999

Does SmartCoolant evaporate?

No. Submer's SmartCoolant does not evaporate at room or at operating temperatures.

1999

Is Submer's SmartCoolant harmful?

No. SmartCoolant is non-toxic, biodegradable, innocuous to hardware and is classified as a food-grade fluid.

1999

Is Submer's SmartCoolant harmful to the It Hardware?

No. On the contrary, it protects it from external elements such as moisture, dust/sand particles and extends its lifespan while reducing IT Hardware failures.

What is the PUE of a datacenter?

Power usage effectiveness (PUE) is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead).

1999

What is the Critical Load of a datacenter?

Critical IT load is the total power required by servers, storage, network and other devices in the data centre that must keep running if there is a loss of utility power. It doesn’t include the load due to mechanical systems, lighting and other requirements.

1999

What is the lifespan of the SmartCoolant? How long did you test it?

The lifespan of the SmartCoolant is 10-12 years. We have done accelerated aging tests at higher temperatures to assure that our fluid can serve you long time.

1999

Do you already have installations? Who are your customers?

Yes, we have installations all over the world. For instance, here in Barcelona we work with BSC (Barcelona Super Computer). In Europe we also work with JRC, CERN, Airbus.

1999

What is your current production capacity?

Our current production capacity is 2.5 SmartPods/day. We are opening a new facility in Barcelona that will allow us to produce 5,000 units/year, to which will be added an extra 5,000 units in the USA. In total, at the end of the year, we will be producing 10,000 units/year.

1999

Is there a SmartPod adapted to cryptomining?

Yes. You can submerged harwares such as ASICs, FPGAs and GPUs. We can accomodate a wide range of form factors.

1999

Would an embedded heat exchanger be a problem for heat reuse?

No this is not a problem. The heat exchanger is connected to an external water loop which would then be connected to a heat pump to achieve heat reuse.

1999

Isn't the price too high for a rack?

No this is not too high as our solution is not only a horizontal rack, but as well the whole primary cooling system. It embeds a heat exchanger and a redundant pumping system, and comes with our non-evaporative dielectric fluid which has a lifespan of 20 years. This is a smart and fully-automated system, and the most advanced and innovative on the market.

1999

How do I perform maintenance on my servers?

The equipment comes with two maintenance rails. Take the server out of the fluid with gloves as it can be a little slippery, place it on the rails, remove/replace the damaged parts and replace it into the fluid. If you need to send the server for bigger maintenance, we will provide you with another fluid that cleans our SmartCoolant.

1999

Do you have certifications?

Yes, our main certifications are: CE, UL, ISO and IP65.
