Engineered Fluids - SLICTanks for Crypto Mining

Gary Testa, President & CEO of Engineered Fluids, introduces us to the Engineered Fluids SLICTank for Crypto Mining device Cooling.

[@minecraftersworld3473]

Gary, I just want to say thank you for sharing so much information on KZbin and your website. You are an outstanding member of the community!

[@garytesta2324]

You are very welcome! A big part of our mission is to educate folks on the amazing opportunities to use our dielectric coolants in a host of different applications! Crypto mining has been an amazing opportunity to highlight what our products are capable of and we are huge support of the distributed cloud and alternative payment methods. Personally, I've always believed that micro-payments holds the key in how to reduce poverty throughout the world by enabling small business and entrepreneurs to reach a wider customer base. Bitcoin and Ether are both enablers, we'll see what else is coming!

Hello Kyle, please reach out to me directly at [e-mail] address your email directly to me Gary Testa please. I'll make sure you get what you need!

[@ΣιμοςΤυρακης]

i will like to know ... all of you with the dry coolers , what you will do in the summer ????

[@garytesta2324]

In the summer the temperature delta between the fluid and the outdoor ambient air temperature is so high that dry coolers are able to continually cool the fluid. Its only when outdoor ambient air temps exceed about 37C regularly that you need to consider using an adiabatic system during times of extreme heat.

[@markcarroll4381]

Good stuff Gary. Very interesting, enjoyed the presentations.

[@garytesta2324]

Glad you enjoyed it

God bless you, John Williams I just received my second payment

[@Invictum594]

What was making all the noise? The pump?

[@bostitchrider2026]

Very nice system. Really, it can be scaled down or up depending on the amount of GPUs/ASICs. Here in the East coast of Canada, this system is ideal. Diverting the fluid in the winter, it can be used as a source of heat for industrial applications or simply heat a home.

[@garytesta2324]

Thanks for sharing!! The reuse of heat is absolutely a huge focus for us! I'm always stoked to hear about people making good use of the heat generated by their miners!

[@guerramm]

Could you tell me what are the characteristics of the pump that recirculates the oil?

[@garytesta2324]

Sure! It's a centrifugal pump that has Viton seals.

[@craigrmeyer]

Why the heat exchanger? Why not skip it, and push the mineral oil all the way out to the outdoor cooler? I don't understand why some people use the heat exchanger, but others don't. Why isn't it an obvious choice, one or the other?

[@garytesta2324]

This particular customer's location required us to use a heat exchanger. In most instances we do not use a heat exchanger but rather we go directly from the SLICTank to the Dry Cooler. However there are certain types of installations where the height difference between the level of the tank and dry cooler require a Liquid to Liquid Hex to prevent the tank from overflowing in the event of a vacuum leak in the dry cooler. This particular system has the dry cooler almost 40ft above the height of the tanks.

[@DimitarManovski]

Great video, thanks :)

[@garytesta2324]

Thanks!

[@dannymendez]

Ok, sounds perfect but. Question and I hope you can answer. What happens if the heat exchanger filter water into the dieléctrico fluid system. How do you prevent this water get in touch with our miner? Thanks. I hope you can look the escenario where the chilling water que be mix it with the dieléctrico fluid.

[@gabriellamas5120]

What was the ambient temperature during this video ?

[@garytesta2324]

If I remember correct the ambient outdoor temp was about 85F during day and about 68F at night. This was done in Sausalito, CA.

[@stevenheroux9199]

i was thinking of the same setup but more in a residential way , 2 miner maybe , and instead of air cooling id pump the glycol into a concrete parking in wintertime (-5 to -30degrees here) and it would keep my driveway dry all years long , any thoughts

[@Stacks79]

Looks great but also looks very very expensive!!

[@troymare4605]

Hi, what is the reason to use a fluid-to-fluid heat exchanger, rather than route the engineered fluid to the dry cooler? Thanks

[@garytesta2324]

Excellent question, in fact we recommend that you do not use a liquid to liquid heat exchanger, unless you already have a chilled water infrastructure in your facility. When we design our turn-key installations we always recommend using what we call the Dielectric Direct architecture where the Dielectric Coolant is pumped directly from the immersion tank to the dry-cooler. This architecture is both more efficient and more cost effective. For those interested in more details, I recommend downloading our how-to guide to SLIC. You can find it here: www.engineeredfluids.com/the-slic-guide

[@2hedz77]

@@garytesta2324 so I am curious if you don't recommend it, why did you do it in this case? Are there some cases when it would be advantageous? Even if you have chilled water infrastructure in place wouldn't it be possible to pipe dielectric instead of glycol/H2O into the dry cooler?

[@tailalmn]

Is this special oil or normal water?

[@theoemanuelsson7465]

Hi Gary, I've got a question regarding your design. I'm trying to build my own. My plan was always to run the bitcool straight into the dry cooler. What are the disadvantages to doing that instead of running water to the cooler and using a heat exchanger?

[@artemtsvetkov3655]

Water has better heat transfer and is cheap to run to outdoor heat exchanger. I would use as little as possible circuit of dielectric fluid, exchange heat to water and dump the heat outside.

[@2hedz77]

He answers the same question in another comment. He actually recommends it...so not sure why they did it.

[@garytesta2324]

This was a specific customer request to use a dual loop system, these days we always do a single loop dielectric direct system. When you do all the math you find out the liquid-to-liquid heat exchanger (HEX) and the extra pump are worth about 100ft of BitCool in a 2in pipe. Unless your liquid cooler is really far away or has a significant difference in height its always better and cheaper to go dielectric direct to the cooling unit!

[@thousandmile9477]

This is the very similar to the hvac setup used to cool most commercial buildings with a closed chilled water loop running to indoor ACUs and exchanging heat in plate/ frame or shell/ tube heat exchanger with an open-loop water line running to a cooling tower. Typically you would separate the two loops first because of contamination from an open loop water line that may degrade your indoor equipment and second due to outdoor condition fluctuations throughout the year where in the winter you might just shut the cooling tower down all together.

[@mikesandoval7628]

@@garytesta2324 what drycooler do you recommend also can we have details on the model and make of that pump?

[@wayneo7220]

I'm curious to know more about the slick remote PSU setup for each rig shown here. Too bad a closeup of the connections didn't make it into the video. I take it they are switching power supplies (220v-12V)? How many amp each?

[@1992jamo]

If the entire thing is producing 67kw, that's 5583A at 12v. If there are 48 miners, that's 116A each at 12v (1392W). That sounds about right for a Antminer S9 14Th.

[@deepnet_0]

hi Gary, do you think this system can be used reliably in the tropics? for places right on the equator line with high air temperature and high humidity.

[@garytesta2324]

Absolutely, in fact we have systems operating in the UAE (hot), Indonesia (Hot and Humid), and here in Florida (Humid) and in all of those conditions Immersion Cooling has huge benefits. In fact for locations directly on the equator, SLIC is probably the only good economical solution.

[@iowa3d353]

Fascinating. I really think this is the future. I would be interested to know how the cost per watt (including initial setup or retrofitting) compares to more traditional cooling methods. Regardless, if you guys ever have an IPO, I want in. Best of luck going forward.

[@garytesta2324]

Thanks for your positive feedback and interest in Engineered Fluids! On average we find that our turn-key solutions average about 40% cheaper than normal air-cooled solutions using air-condiitioning.

[@tapasranjan812]

If the miner are submerged ,where so much noise coming from background ?

[@garytesta2324]

The noise you hear is the fan noise from the PSUs of the miners. These are being overclocked at about 140% so they are working pretty hard.

ASICs have a typical skin temp of between 70-95C. So the fluid is VERY cool comparatively!

[@crypto.q1600]

Guys, did anyone try immersion cooling for hashing boards without heat sinks?

[@garytesta2324]

Yes, but it doesn't work ASICs are too hot and the fluid flow rates would be to high, your looking for a balance between cost of high flow and a cheap heat spreader!

[@kingtom6433]

Can I hook this up to my pool?, How many miners to 20000L pool, Ave temp 15 degrees

[@garytesta2324]

Yes you sure can! Using a simple liquid to liquid heat exchanger you can reuse the heat for your pool, home water heating, hydronic heating, green house, etc.

[@Anomaly417]

why not just slow the pump speed or fan speed if nearing freezing points?

[@garytesta2324]

So, while you will definitely want to turn down your fans, you don't want to turn them off if you live in an area where it snows or gets office as the rotating fan sheds ice and protects the bearings from intrusion. Regarding the pump you don't want to freeze your miners by dumping in super cold BitCool which is what will happen if you just turn down the speed of the pump and you also risk burning your miners. Best option is to keep the BitCool moving at about 2-3L/min. You miners are most efficient in BitCool that is above 50C! We've found that you want to keep your BitCool at the best temperatures the by-pass loop is the way to go, as you can properly regulate the temperature with a simple valve turn and you keep the BitCool flowing.

[@Anomaly417]

@@garytesta2324 wait so I have an immersion cooling system with 6 antminer s19j and our temperature shut off is at 52c is that too low I don’t understand because then the miners itself is reporting over 65c I feel as though the miner reports the wrong temperature so we just use the liquid temperature to get an idea, our output liquid temperature is around 50c with 6 of them running

[@garytesta2324]

Absolutely, we're about to release our next generation 6 tanks in July 2022

[@Saturdaymorninghero]

so the ec100 doesn't evaporate like novec does?

[@garytesta2324]

That is correct none of our Coolants have boiling points and all have very low vapor pressures. We have customers that have been using our coolants in unsealed tanks for years with no evaporation or loss of coolant. In addition, unlike Novec ElectroCool and BitCool do not absorb water and humidity. This prevents them from losing their dielectric properties and prevents the oxidation (rusting) of iron based metal alloys that occurs in Novec. Those rust particles are very conductive and end up floating around in the fluid.

[@willyfromthehillies]

What's the approximate cost per tank setup?

[@garytesta2324]

Hi James just send a request for quotation to: [e-mail] and we would be happy to get you a full price quotation for a tank.

[@alice20001]

How many watts do these generate in heat?

[@garytesta2324]

Generally speaking the miners generate as much heat in watts as they utilize in electrical energy, since they have no kinetic lost after the removal of the fans, all the electrical energy is transformed to heat.

[@jabuki2]

i was hoping to see what your filtration solution is for this system. you can't run an open air fluid system 24/7 without it getting dirty. While you may be selling fluid, replacing the fluid rather than filtering it isn't a valid solution.

[@garytesta2324]

We use a simple fuel oil filter or disel fuel filter in a by pass configuration where we only filter about 2% of total flow. We have systems operating at oil sites in the desert where there is more than 2in (50mm) of mud in the bottom of the tank without impacting operatings. Not ideal set up, but the fluid is VERY resilant.

Gary, how come we went with a 2” supply and return with such low GPM numbers

[@garytesta2324]

We really don't need high pressure and high flow rates. In larger systems the 2" supply is easy to manage and the pumps are easy to find in this size. If you only have one tank, you can down size the piping to 1" and use a 1HP pump, but when your doing 30 or 40 tanks in a single module, 2" tank plumbing is the way to go.

Does this violate the warranty of the miners?

[@garytesta2324]

The simple answer is yes, but frankly most of the miners you buy have pretty lousy warranty support to begin with. However, we do offer our DS-100 cleaning solvent which will allow you to completely clean the miner so that it can be returned with no indication that it has ever been immersed in our coolants. Also, we should note that Miners immersed in our Coolants have been shown to be 3x more reliable requiring less rebooting and significantly longer operating lifetimes than the Air cooled equivalents. The reason is that immersion in our coolants provides significantly better temperature control and less temperature gradient across the device. We currently have over 200K miners operating in our coolants globally and the failure rate is about 10% of what our customers see in air, and none of the failures is attributable to being in the coolant. Most failures are caused by bad PSUs or power cap failures on hash boards.

You need to find a better way to dissipate heat. This is wasted energy. It could be house heating, water heating, pool heating....

[@garytesta2324]

Jonathan, I could not agree with you more! We always encourage our users to find ways of making use of the thermal energy contained in our Dielectric Coolants. House heating with hydronic systems is a very popular approach to heat dissipation with home users, as well as pool heating as you point out. In addition, some of our industrial scale users use the thermal energy to pre-heat water for boilers, heat green houses, farmed fish ponds, roads, sidewalks, and similar applications of which make better use of the energy rather than just expelling it into the air.

[@nickmorozyuk3536]

how unfortunate that such a solution is so energy inefficient and using oil is pretty much a fire hazard. 2 phase > 1 phase 24/7/365

[@garytesta2324]

Hi Nick, I think you need to learn more about our Dielectric Coolants and the entire immersion cooling process before making a final judgment on Immersion Cooling with Engineered Fluids Dielectric Coolants . Our Dielectric Coolants and Immersion Cooling in general is far safer and efficient that 2 Phase cooling and the fire risks are minimal to non existant since our fluid is not an oil. I agree that the use of Oil in immersion cooling is dangerous and poses a fire risk as well as health risks.

[@garytesta2324]

Hugo, its a shame that you see this as a diaster rather than the techology that is going to save more energy on the planet than any other. Think about it. Data Centers use 4-8% of world energy and burn more than 3% of the world's potable water every year. By transitioning to SLIC we would reduce that number to 2-3% of energy and elimate water use to below .04%. In addition, our Dielectric Coolants are Biodegradable, non-toxic and non allergenic. We also have a ZERO WASTE recycling system where all of our customers can return used fluid to us and we fully recycle it into new product. I challenge you to show me any other technology that will do more to save our planet!!!
