The Antminer S19 Pro Hydro is Bitmain's water-cooled version of the S19 Pro generation. The Bitcoin miner is built for the SHA-256 algorithm and can be used to mine Bitcoin or Bitcoin Cash. Our two levels are 177 and 184 TH/s, each at 29.5 joules per terahash. Without fans it comes to 13 kilograms; the supply is three-phase, 342 to 418 volts.
Model 208-A comes in seven levels from 154.5 to 184 TH/s, all at 29.5 joules per terahash. Unlike the air-cooled units, Bitmain references these figures to a chip temperature of 65 degrees, with three percent tolerance on hashrate and five percent on power and efficiency.
The housing measures 336 × 175.5 × 208 mm, the carton 570 × 316 × 430 mm at 15.6 kilograms; noise is 50 dB. There is no pump inside the unit; as with nearly all hydro miners, the external cooler has to push the water through the miner, and without such a loop it does not run.
The water may be 20 to 40 degrees at the inlet and flows at 8 to 10 litres per minute at no more than 3.5 bar, connected via DN10, with deionised or pure water as the working fluid. If temperatures drop below freezing where the miner is operated, antifreeze must go into the loop, no exceptions. Room temperature is allowed from 0 to 40 degrees while running and from minus 20 to 70 in storage, with 10 to 90 percent humidity provided nothing condenses.
It hangs on the grid three-phase at 342 to 418 volts and 47 to 63 hertz; Bitmain puts the input current at up to 30 amps, and the network socket is an RJ45 at 10/100 Mbit.
Custom firmware for the S19 Pro Hydro is available from Vnish; Braiins OS does not list it among its models. With it, every hashboard can be run slower or faster on its own, faster meaning less efficient. Installation before dispatch costs 29.90 euros net per unit with us and is limited to miners you operate yourself, hosting units excluded. Whoever flashes gives up the warranty from Bitmain and from us.
A ready-made cooling unit for this miner is the Lian Li cooling unit, sized for exactly one machine.
As standard, Bitmain gives a 365-day factory warranty on the machine, counted from the shipping date; our standard price always includes our own warranty.
The direct successor is the Antminer S19 Pro+ Hydro, followed by the Antminer S19 XP Hydro. The change of generation is marked by the Antminer S21 Hydro, the following one by the Antminer S23 Hydro. Ordered by efficiency:
To the S19 Pro+ Hydro the drop is two joules per terahash, just under seven percent. The S19 XP Hydro then takes off almost seven joules per terahash, a quarter, the S21 Hydro another five joules or so, and the S23 Hydro cuts the figure by a good third more, to below 10 joules. The daily yield of the S19 Pro Hydro next to every other unit we sell is shown in the miner comparison.
The S19 Pro Hydro frequently had broken hashboards. Starting it up is complicated as well: the water has to be at a certain temperature, and if it is too cold, the miner does not start.
The successors of this first hydro generation, such as the S21 series, are much better.
What the S19 Pro Hydro yields at your electricity price is worked out by the Bitcoin mining calculator for the level you choose. The cockpit feeds it the Bitcoin network hashrate and the price; one level further in the cockpit lies the line-up of Bitcoin mining pools, each with share and fee.
When you buy mining hardware via Cryptohall24, you get a guarantee of 12 months In contrast to manufacturer warranties, our warranty only begins when the hardware is sold to our customers and not as soon as it leaves the factory. Since there can often be several months between production and sale in the mining market, our customers often have a longer effective protection than with the pure manufacturer's warranty.
Optionally, the hardware can be added to insured for up to 36 months become.

The process is clear and done in a few steps: you enquire about the device you want, you receive a written quote with the final price from us, and as soon as you accept it, we issue the invoice. After full payment is received, we trigger the order and the hardware is on its way to you.
That way you know where you stand at every point - from quote to delivery, a continuously supported process with a personal contact.
You can pay conveniently by bank transfer in euros, in crypto (Bitcoin or USDC) or in cash against a receipt.
As throughout our business, payment is in advance: we trigger the order as soon as payment has been received in full. That keeps the process clean and predictable for both sides.
Yes, discounts are possible for larger quantities. How large they are depends on several factors - the device, the quantity, the delivery location and the respective procurement conditions.
That's why we state the right price best directly in an individual quote. Just tell us the model and the quantity you want and we'll work it out for you.
On modern ASIC miners the power supply is built firmly into the machine and is therefore always included - it does not have to be bought separately. An external power supply only existed with very old first-generation models.
So you receive a ready-to-run device. Whatever else specifically belongs to the respective product is stated in the product description; in case of doubt we clarify it in the quote.
You can see availability directly on the product; in case of doubt we confirm it in the quote. The majority of our hardware is located in our main warehouse in Hong Kong and is shipped from there directly to your destination.
Individual devices are in stock in Germany (Hamm) - those reach you particularly quickly. We state the concrete delivery date bindingly in the quote, as soon as device and destination are clear.
We deliver worldwide. We handle the shipping and the complete import processing including customs clearance for you - you don't have to deal with it yourself. We state the shipping costs transparently in the quote.
That way the miner arrives ready to use at your place or the desired site. On request we deliver directly to our hosting, then the device goes into operation without a detour.
To operate at home or in your own business you mainly need three things: a suitable power connection (ASIC miners draw several kilowatts continuously, large devices often three-phase power), enough space with ventilation, and a stable internet connection via LAN.
On top of that come noise and waste heat: air-cooled devices are very loud and heat the room noticeably. Anyone who doesn't meet these requirements usually has the miner hosted - then we take care of power, cooling and operation.
Commissioning is straightforward: connect the device, plug it into the network and configure it to your mining pool and wallet. After that the miner runs around the clock.
We don't leave you alone with it - we support you with setting up pool and wallet and the first steps, even without prior experience. Your personal contact is available for questions.
As a German company we offer you 12 months' warranty on your hardware as standard.
Alternatively, you can exclude the warranty in the purchase contract and handle it via the manufacturer's warranty - then the device becomes cheaper. We offer both routes; which one makes sense for you we clarify in the quote.
Yes. You can buy the device from us and have it hosted in the same step - then it runs at a site with low-cost electricity, without noise and heat at your home.
For many this is the most economical way. You can read how hosting works on our hosting page.
We sell our devices to businesses (B2B). A statutory consumer right of withdrawal therefore does not apply in B2B business; in addition, we procure and import the hardware specifically for your order.
So you buy in a targeted and binding way. That's exactly why we calmly clarify the right device for your project before the quote - so you make the right choice from the start. If you have questions before buying, we are always reachable.
