The Bitdeer SealMiner A4 Ultra Hydro is the flagship hydro-cooled ASIC miner in Bitdeer’s A4 series, launched in April 2026. Its breakthrough achievement is shattering the 10 J/TH efficiency barrier, delivering an industry-leading 9.45 J/TH while producing 886 TH/s of SHA-256 hashing power. This positions it among the most energy-efficient Bitcoin miners available and marks the successful fulfillment of Bitdeer’s chip development roadmap.
The A4 series includes three models for different deployment environments :
| Model | Hash Rate | Power | Efficiency | Cooling | Best For |
|---|---|---|---|---|---|
| A4 Ultra Hydro | 886 TH/s | 8,372W | 9.45 J/TH | Hydro | Maximum efficiency & flagship performance |
| A4 Pro Hydro | 680 TH/s | 7,412W | 10.9 J/TH | Hydro | Balanced hydro performance at lower cost |
| A4 Pro Air | 336 TH/s | 3,662W | 10.9 J/TH | Air | Facilities without liquid cooling infrastructure |
Breaking the 10 J/TH barrier represents a significant industry milestone. For context, older S19-era machines typically operate above 30 J/TH. This means the A4 Ultra Hydro can produce the same hashrate at approximately one-third the electricity cost of previous-generation hardware. In the post-halving environment where block rewards are 3.125 BTC, operational efficiency is the difference between profitability and running at a loss.
As a SHA-256 ASIC, it can mine all SHA-256 algorithm cryptocurrencies, including :
-
Bitcoin (BTC) – Primary target
-
Bitcoin Cash (BCH)
-
Bitcoin SV (BSV)
This is an industrial-scale miner requiring professional infrastructure:
Electrical Requirements:
-
Voltage: 380-480V three-phase industrial AC
-
Power: 8,373W per unit with up to 97% PSU efficiency
-
Per Rack (21 units): Approximately 18.6 PH/s total hashrate at ~175 kW continuous power draw
Cooling Requirements:
-
Hydro-cooling loop: Requires external Cooling Distribution Unit (CDU), pumps, piping, and heat exchangers
-
Operating temperature: 5°C to 45°C (can operate up to 55°C with hydro cooling)
-
Noise: 50 dB (quieter than air-cooled equivalents)
Is it suitable for home mining? Absolutely not. The A4 Ultra Hydro is designed exclusively for professional mining farms, data centers, and large-scale hosting facilities with industrial power and cooling infrastructure.
