Both miners have an energy efficiency of 14.9 Joules by Terahash (J/TH).

The Sealminer chips are manufactured alongside TSMC, a recognized smelting of semiconductors.
The Bitdeer Technologies Group company, based in Singapore and focused on mining and high -performance computing solutions, announced the launch of its new series of Bitcoin mining machines, the Sealminer A2 Pro. These editions incorporate new equipment the Bitdeer Asics A2 line.
This development, made public on March 17, 2025 through an official press release, Enter the A2 Pro Air and A2 Pro Hydro models.
According to Bitdeer, the technical specifications of the Sealminer A2 PRO reflect an approach in optimizing the balance between power and energy consumption in Bitcoin mining.
The air refrigerated model, the A2 Pro Air, It offers a hash rate of up to 270 terahas per second (TH/S)with a consumption that ranges between 3,790 and 4,050 watts. This translates into an energy efficiency of 14.9 Joules by Terahash (J/TH), an indicator that measures how much energy is required to generate each calculation power unit.
For its part, the A2 Pro Hydro, with liquid cooling, elevates yield to 530 th/s, Although its consumption increases to a range of 7,450 to 7,900 watts, maintaining the same efficiency of 14.9 J/th. This efficiency improves with previous Bitdeer models, such as the Sealminer A1.
The Sealminer A2 Pro series marks a great advance in the efficiency of the power supply, reaching up to 97%. The A2 PRO HYD has improved performance at high temperatures, efficiently operating with input water temperatures up to 60 ° C and output temperatures up to 70 ° C. Both models retain the low noise design of the series, which minimizes operational noise disturbances.

Comparing the new Sealminer A2 ASIC
To understand these specifications in perspective, it is useful to compare them with other equipment of the same brand and market. The Sealminer A1, for example, reached an efficiency of 18.1 J/TH integrating the Seal01 chip, according to previous Bitdeer data. The passage to A2 Pro Air improves efficiency with 14.9 J/TH, which shows progress and reduction of calculation unit consumption.
The A2 Pro Hydro, with its 530 TH/S, It aligns with high -end equipment like the Antminer S21 XP Hydro of Bitmain, which delivers 500 TH/S with an efficiency of 12 J/th. Although Bitdeer’s model exceeds Bitmain in Hashrato, the difference in efficiency is narrower, indicating that the A2 Pro Hydro is designed for large -scale operations where liquid cooling can guarantee greater stability and durability.
In turn, the A2 Pro Hydro, with its 530 TH/S, is still distant in hashrate from Bitmain Antminer S21e XP Hyd 3U, which has a capacity of 860 TH/S. This Bitcoin miner was launched in January 2025 and has an efficiency similar to it, 13 j/th.
The Sealminer A2 carry chips manufactured by Bitdeer
According to Bitdeer, a key component of the Sealminer A2 Pro is the use of Missal series mining chips, developed by the company itself.
These chips, manufactured in collaboration with TSMC, a recognized casting of semiconductors, are the basis that allows the efficiency of 14.9 J/TH of the new miners of the Bitdeer A2 series.
This internal chips development reduces, on the one hand, the dependence of external suppliers, unlike other brands that resort to third -party chips, and gives Bitdeer greater control over the optimization of their equipment. On the other hand, these chips are proprietary code, which means that its code is not open and cannot be audited exhaustively.
The Seal Chips series, present from the Sealminer A1, has continued to evolve. As Cryptonotics reported, recent tests point out that the Seal03 chip, the last of the series that could leave in 2025, is still in a prototype phase. According to information, This chip already achieves an efficiency of 9.7 j/th in energy saving mode, which suggests future improvements in the company’s miners, although it is still tested within complete mining equipment.
According to Bitdeer, the launch of this chip is scheduled for 2025, after it was announced by the end of last year.
Seal03 has an energy efficiency of 10 J/TH chip, and energy consumption is expected to be wall assembly between 11 j/th and 12 j/th. The third generation Sealminer mining machine is expected to be manufactured by mass and delivered in the second quarter of 2025.
