SealMiner A3 Pro Hydro for sale, 660Th/s 8250W Fast and efficient mining BTC

SealMiner A3 Pro Hydro for sale

The SealMiner A3 Pro Hydro from Bitdeer is a flagship, hydro-cooled Bitcoin miner built for SHA-256 algorithm operations. Designed for serious mining enterprises, the A3 Pro Hydro delivers a hashrate of 660 TH/s with a power consumption of 8,250 W, yielding an energy efficiency of 12.5 J/TH. This efficiency places it at the upper tier of hydro-cooled ASIC miners, giving operators a strong performance per watt advantage.

One of the defining advantages of the SealMiner A3 Pro Hydro is its hydro-cooling architecture. By circulating coolant directly over the hottest parts of the ASIC circuitry, it more effectively removes heat compared to conventional air cooling. This allows the miner to maintain peak performance for longer without throttling, reduce thermal stress on components, and support denser deployment in rack systems while managing heat pathways more efficiently.

Because of the superior cooling, the A3 Pro Hydro operates with reduced acoustic impact. While many air-cooled units require high-speed fans and generate significant noise, the hydro system enables quieter operation. This helps in environments where noise control is important or where mining equipment is closer to occupied zones or shared infrastructure. The lower reliance on massive airflow also reduces dust ingress and mechanical wear associated with fans.

Given its high throughput (660 TH/s) and the 12.5 J/TH efficiency, the SealMiner A3 Pro Hydro offers strong performance density. In facilities where space, cooling capacity, and electrical infrastructure are premium, each unit’s output is maximized relative to its footprint. The hydro setup enables tighter thermal management and allows for compact racks or clusters without the overhead of massive air circulation infrastructure.

The miner is engineered for deployment in professional data centers or mining farms with access to liquid cooling systems. Its form factor is streamlined (dimensions roughly 665 × 482 × 86 mm) and its weight is about 20.5 kg, making it feasible to integrate into existing dense layouts. The cooling plumbing, coolant control, and rack piping requirements add complexity—but that tradeoff is justified by the gains in performance and thermal stability.

Reliability is central to the SealMiner A3 Pro Hydro’s design. With lower junction temperatures, less temperature swing, and better heat dissipation, component wear is reduced. That contributes to longer lifecycle and fewer failures. Firmware and chip control logic are tuned to take advantage of the stable thermal environment, enabling tighter tolerances and consistent hashrate delivery under varying supply and ambient conditions.

From a power infrastructure perspective, the A3 series—especially the Pro models—is equipped with highly efficient power supply units. These high-efficiency PSUs help minimize losses in the conversion path, ensuring more of the input electricity becomes productive hashing work. In large operations, that incremental gain in power chain efficiency adds up significantly.

Operating conditions for the SealMiner A3 Pro Hydro are designed to be forgiving across many environments. The miner supports a temperature range (typically 5-45 °C) and humidity up to ~95%, allowing it to be placed in varied regional settings. Because cooling is handled by liquid systems, it is less sensitive to changes in ambient air temperature or airflow conditions.

In sum, the SealMiner A3 Pro Hydro offers a compelling solution for high-end Bitcoin mining: 660 TH/s, 12.5 J/TH, and advanced hydro cooling to support consistent, dense, and quieter operations. For mining farms equipped to handle liquid cooling infrastructure, it provides excellent performance per watt, enhanced thermal stability, reduced wear, and increased operational longevity. As a hydro-cooled flagship in the SEALMINER A3 lineup, it targets operators who want maximum throughput under controlled thermal and acoustic environments in 2025 and beyond.

Specifications of SealMiner A3 Pro Hydro

First of all, thank you for your interest and support to X-ON MINING. In order to avoid misunderstandings in the process of purchasing a miner, please read all the following notes carefully before placing your order. Thank you very much for your understanding!

1 – Given the specific dynamics of the miner market, when we receive your payment, the miner’s price may have changed and we may need to refund your order.  

We use batch processing for all mining machine orders, and the quantity of each batch is very limited.  Even if the same type of mining machine, different batches of mining machine prices are not the same.  They’re selling fast.  Given the highly variable market and demand, the prices of stock miners may vary from day to day.  Therefore, so there is a possibility that by the time we receive your payment, the price of the mining machine has gone up and we need to refund your order.

2 – About stock miners

The delivery date of stock asic miner is 3-7 working days.  Once we receive your order, we will immediately notify our technical center staff to test the machine you ordered to make sure it works well.  We’ll also send you a video for confirmation.  We will send the machine to you only after we confirm that all the properties of the machine are correct.  Then, we will give the machine to our freight forwarder.  We will update the waybill number on our website and you will receive a detailed email.

3 – About pre-purchase miners

The actual delivery date of the pre-ordered miner depends on the miner delivery date of the factory.  We will indicate on the order page the estimated delivery month of the pre-ordered miner for your consideration.  However, there may still be a delay in delivery.  First, if the factory delivery date is delayed, then the delivery of the X-ON MINING Mining machine will also be delayed.  It is also possible that the plant will not be able to produce the mining machine within the expected time, in which case we will process your order for a refund.
