Complex to build,
simple to run.

We manufacture the cooling, supply the power gear, and deploy megawatt blocks in days, so your site energizes on schedule and stays online after it does.

Industrial mining,
made straightforward.

Every tank, manifold, panel and container is built and tested on our own line before it ships, to CSA, UL or CE as your site needs. Six years of in-house R&D and 400MW deployed across 40 countries, behind one set of drawings, so what lands on your pad is what passed FAT.

Hydro and immersion loops hold the chips at a steady temperature from -30°C to 50°C ambient. Miners stay online where an air-cooled farm throttles or trips, and boards stop cycling hot and cold every time the fans ramp.

Every miner, pump and dry cooler switches locally or from the Fog web portal, with full API access. One year of FogCare is included, FogCare+ runs to ten, and spare parts sit at three levels, so a failed pump is a part on a shelf rather than a shipment.

Liquid cooling,
efficient either way.

Factory pre-assembled, built to order in 30 to 50 days. What differs is block size, form and which miners it takes.

Power gear,
in weeks.

75kVA to 500MVA, up to 345kV. US-stocked pad-mount units ship in 14 days, so the transformer does not hold your energization date.

1200A to 4000A, engineered to your single line and built in around eight weeks. UL, cUL, ANSI/IEEE, NEMA and DOE listed.

The cooling and the power gear come from one company, so the drawings agree and there is one number to call when the schedule slips.

Running sites,
in operators' words.

Four air-cooled containers running on the Simple Mining site, dry coolers open above each
10MW Liquid-Cooled Site in Iowa

“The site has now run 90 days without an interruption. What I did not expect is that Fog stayed involved after deployment, and their engineers still walk through our operating questions with us every month.”

“Absolutely thrilled about making the move. The uptime is there, it is so much easier on the equipment, and the dust and dirt stay outside with the dry coolers. We will never go back to air after taking the jump.”

“I’m truly amazed. The BC20 containers outperformed every expectation in -30°C extremes—far beyond my expectations. Cold resistance? More like cold dominance. I think it’s time we order more.”

Walk a site, or walk the line.

Specifications are one thing. We will bring you onto the factory floor to watch your own containers being built and tested, and where an operator agrees to it, put you in front of a site already running. Tell us which and we will arrange it.
