400amp 220 volts sounds better

5 amps a unit

derate 20%

320 amps divide by 5 = 64 max

so running 55 is possible

now 1100 watts = 4000 btu

55 x 4000 btu = 220,000 btu

you need lots of exhaust fans

as for network a 5 port lan router one from the modem then connect to 2 x 16 port switches

do 5 miners to a rasp pi3 put 6 rasp pi's on each switch if the gear dies you can move all the rasp pi's to one switch.

Thanks @philipma1957!!, thats the kind of info I was looking for. Cheers
We have two 24" 24,000 CFM fans we were thinking of using somehow. I am seeing from your calculations, thats no where near enough to keep the pressure ratio correct.

Any suggestions??

I hope you hear back from them also. We are exploring GPU mining, but the cards are over priced locally, so we need to find bulk suppliers.

I just got an email from Canaan a few minutes ago as we requested their company registration info before wiring any money. Have you reached out to them? (sorry if a silly question), we have been very persistent with them, but always very pleasant.

Thanks @goose1072!

okay my smaller solar array farm has 2x 1600 cfm

and is doing 4 avalons and 5 s-9s about 10-11 kwatts no ac air to inject and with careful heat shielding it is okay.

so 3200cfm can do 10kwatts

you have 15x the cfm I have

so I have 9 pieces

you can cool the gear off but you need a tunnel effect

give me a few minutes to link photos.
