you can't run 100 units.

you can run 80-90.

350 x 80 percent = 280 kwatts once you derate for safety.

280/3 = 93

that is assuming every s19 uses 3kwatts. that is a fair assumption.

cooling is complex. but a s19 pushes about 450-500 cfm

90 x 500 = 45000 cfm minimum exhaust.

three of these would work/

and two of these for intake.

90-m2 is 900 square feet or 30 by 30 foot room

if you have room for the 3x 48 inch exhaust fans on 1 wall

and room for intake air at least 4 x 48 inch square I would think you can cool it.

USE WASHABLE AIR FILTERS LIKE THESE

how to wire by 16amp do you mean a 20 amp derated to 16 amp for 24/7/365 use.

as 16 x 240 = 3840 watts derate to .8 x 3840 = 3072 you would be borderline.

here in USA we use

a 20 amp. so 20 x 240 = 4800 watts derate by .8 = 3840 watts and no issues.

I do recommend separate circuits for each unit.

if you do 2 to one 40 amp you could have one unit shut off and not pull power while the other shorts and pulls 40 x 240 = 9600 watts

Wow amazing, thanks.

Does the gears has to be just in one vertical line?
