The Bitdeer SealMiner A3 Pro Hydro represents the cutting edge of industrial Bitcoin (BTC) mining. Powered by Bitdeer's in-house SEAL A3 chip, it delivers a massive 666 TH/s hashrate at a class-leading 12.5 J/TH efficiency, drawing 8325 W. Its integrated hydro (liquid) cooling system dissipates heat far more effectively than air-cooled rigs, enabling stable, near-silent 24/7 operation and a longer hardware lifespan. Built for data centers, hosting facilities, and high-throughput mining farms that demand maximum hashrate per rack.

Advanced Hydro Cooling Integrated liquid cooling keeps chips cool for stable, near-silent, high-density deployment. |
Elite Efficiency 12.5 J/TH means more Bitcoin per watt – lower running costs and stronger margins at scale. |
|
Massive 666 TH/s Output Top-tier hashrate stays competitive as Bitcoin network difficulty keeps rising. |
Reliable & Warrantied Engineered for continuous 24/7 industrial use, backed by a 365-day factory warranty. |
Technical Specifications
What's Included in the Package
Note: A compatible external water-cooling system and PSU are required and are typically not included. Please confirm the exact shipment contents with our sales team before ordering.
Worldwide Shipping & Deployment
Built to the 380–480 V industrial standard used by mining farms across the USA, Canada, the European Union, the Middle East, Central Asia, Russia, Ethiopia, Paraguay, and beyond. With its hydro-cooled design and 12.5 J/TH efficiency, the A3 Pro Hydro is ideal for high-density data-center racks and immersion / liquid-cooling facilities where heat, noise, and space are tightly managed. DDP shipping options available on request.
Frequently Asked Questions
Can I run the SealMiner A3 Pro Hydro at home?
It's designed for industrial facilities, not residential use. It needs a compatible external water-cooling loop, 380–480 V high-voltage power, and proper airflow management – best suited to farms and data centers.
Why choose hydro cooling over air cooling?
Liquid cooling dissipates heat far more efficiently than fans, giving more stable operation, much lower noise, higher rack density, and longer hardware lifespan in dense deployments.
Which coins can it mine?
It runs the SHA-256 algorithm, so it mines Bitcoin (BTC) and other SHA-256 coins such as Bitcoin Cash (BCH). It supports both pool and solo mining.
How efficient is it compared to other miners?
At 12.5 J/TH, the A3 Pro Hydro is among the most efficient SHA-256 miners available – meaning more hashrate per watt and lower electricity cost per Bitcoin mined.
What warranty and shipping do you offer?
The unit comes with Bitdeer's 365-day factory warranty from the shipment date. We ship worldwide, with DDP options available on request – contact our sales team for rates and lead times.
