12KW Water Cooler for Hydro Miners

Setup and operation

Plan a dedicated, properly fused circuit, dust-free intake air and an unobstructed exhaust path. Air-cooled miners run at 70–75 dB and belong in a basement, garage, workshop or server room rather than a living space. Setup takes a few minutes: connect the network cable and enter pool and wallet in the web interface — on request we configure the unit before shipping.

Shipping, warehouse and delivery time

Stocked units ship within 2–4 business days from our warehouse in Bavaria, Germany. Because the hardware is already imported and cleared inside the EU, there is no import VAT, no customs paperwork and no waiting for air freight from Asia. Models sourced directly from the factory show their own delivery time on the product page.

We ship insured to Germany, Austria, Switzerland and the rest of the EU. Orders above 1,000 € ship free within Germany, and express shipping is available for stocked units.

Payment, invoice and warranty

You can pay by bank transfer, credit card, PayPal, Apple Pay or cryptocurrency. Every order comes with a proper invoice showing VAT. EU business customers with a valid VAT ID are invoiced at 0 % under the reverse-charge scheme, and we can switch your session to B2B mode with net prices.

New and used miners are covered by statutory warranty under EU law. Used units are tested, cleaned and shipped with a logged hashrate; the exact scope is stated on each product page.

Advice before you buy

We help you check electricity tariff, power connection, cooling, noise and realistic payback before you order — including when the honest answer is that a machine will not pay off at your kWh price. Send us your electricity cost and the planned location and we will run the numbers with you.
