Compute infrastructure that ships.

A miner turns almost all of the power it draws into heat, and that heat has to go somewhere around the clock. Air cooling is cheap and simple. Hydro carries the heat away in water, runs quieter and lets you use the heat.

Air

The cheapest option per unit, and anyone can service it. It is loud, though (an Antminer S21 runs at about 75 dB), and the heat leaves as warm exhaust air.

Hydro

Usable heat

A water loop takes the heat straight off the chips. The units are quieter, you can pack them closer together, and the warm water can heat a building.

Heat Reuse

Heating with a miner

An ASIC turns practically all of the power it draws into heat. A hydro unit passes that heat through a heat exchanger into a buffer tank or heating loop. Whether it pays off depends mostly on what you pay for electricity. The Heat Reuse page does the math, including the cases where a heat pump is cheaper.

FAQ

Questions before you buy

01Is the hardware new?

ASICs are mostly new; used units are always labeled as used and come with a test report. Before dispatch every unit is powered on and briefly checked for function.

02How can I pay?

Bitcoin on-chain (Lightning on request), USDT or USDC on Ethereum, Tron, BNB Chain or Polygon, or a SWIFT transfer in USD. We only accept bank transfers from company accounts; the bank returns payments from personal accounts. The shop price is the price of the hardware, and shipping is added in the cart. There are no hidden surcharges and no markup on exchange rates.

03How fast do you ship?

In-stock units usually leave the warehouse 24-48 hours after payment arrives. Delivery then takes 3-7 days for most countries. For futures, the expected date is shown on the product. We ship DAP and prepare the export documents.

04How do I order larger quantities?

Just add the units to your cart. For several units you can also request a quote: tell us the model, quantity and destination country, and you get a binding quote with price, lead time and freight, usually the same day and always within 24 hours.

05Do you ship to my country?

We ship worldwide under DAP. You are the importer and pay customs duties and import VAT in your country; we prepare the export documents. To selected countries we also ship DDP: we handle customs clearance, and the import VAT is already in the cart.
