Another question came to mind. Since these units are portable and would sit outside, how would you pre-heat the miners if the unit was shut down in the winter? I understand you cannot start up miners if it's -20 degC outside and the miners are at that temperature. So you would need a way to preheat them would you not?

Nope. Pre-heating miners is not a concern. You can leave the vents off for a minute, that will do Wink

I have been told on other threads I should not start up my Antminers until it is close to or above 0 deg C. I could add an electric heater to start up before my controller starts up the miners I guess, and have the miners start after so much time has passed (enough time to warm up the miners).

if it were really a concern adding 10-20 kilowatts of electric heaters for 10 or 20 mins before firing them up would fix it. be cheap to add i would think.

I have a concern with your design since there is no de-humidification, is there a risk that fog, rain or high moisture will end up in your miners and cause damage? It looks to me you have a simple exhaust fan set up creating negative pressure in the container and air is supplied through the bottom filters. This does not address potential moisture concerns?

Thanks for the help. Did you find a partner in NA to sell these units after? I live in Canada

There are no moisture concerns as long as you heat the incoming air. Even if the relative humidity is 100%, as soon as you heat it up with the absolute water content staying the same the relative humidity gets lower.
The only thing which would lead to a condensing condition on the miners would be a power outage at night, with the hardware cooling down and then the environment warming up faster than the hardware...

There is a company in Canada called KubeData which made a product called CryptoKube.

I went to both links but did not find where they are in located in canada exactly.
To ship one of those across the country would cost a couple of thousands. So it would help to know where they are operating out of and in which province they were be able to drop that container.
Thanks.

Polivka GmbH, I really like your idea of using shipping containers as data centers.

I wonder why you have chosen to pull and push air through the floor? I guess that you preferred water tightness over efficiency of the air movement & cooling. One could design an intake from the bottom of one side, then an air velocity through the miners and then an exhaust on the top of the other side. This design would be much better for hotter days. Rain could be managed with deflectors for intake and gravity flaps on exhaust fans for the other side.

Did you experienced troubles with water being sucked in or with leakage?

No water sucked in - snow would be more prone to any ways, but also isn't a problem as long as you have filters.

This design also allows to integrate silencers, which you often need - depending on the place you put the container.

I am wondering if you ship to the United States and how much would it cost to send from Austria.
Cause the person who asked you about this is right. That company doesn't sell them anymore that is close enough.

Shipping cost is not the issue - lead time probably is.
Also you guy's have completely different electrical standards in USA, I wouldn't even be able to buy a single component around here.
Shipping only the steel structure with the fans would be doable.

Hi,

I have 3 slightly modified Container for sale.
At the moment they are located in Austria, powerprice there is 0,055€ per kwh (netto)
But they can also be transported to a new location easily.

A few questions for ya:

  • How do they get internet, cellular modem?
  • What kind of theft prevention is in place? It's pretty easy to cut through a shipping container wall with the right tools, that's a lot of value a thief could easily grab in under 1 hour at night.
  • What happens if they are shut down in cold weather, how do you pre-heat them prior to re-start? How do you prevent them from getting too cold during a shut-down?

Pretty cool tho.
Thx

1) Yes
2) It's also pretty easy to smash the window of a jeweler. Or cut into a house (at least in America...). Insurance makes you sleep better, insuring the contents of a shipping container is nothing new.
3) Can you point me to any posting that shows that any professional mine has heaters in place?

Also what is the spec of the exhaust fans?

First post. They changed in the meantime and got even stronger. Also I'm working on a 4 - Fan version right now, pretty excited about that Wink

How many Bittmain AntMiner S9s would fit in one of these containers?

Also, why do some containers have a skirt on the bottom?
