Bitdeer SealMiner A4 Ultra Hydro (886Th/s)

The Bitdeer SealMiner A4 Ultra Hydro is a cutting-edge hydro-cooled ASIC miner engineered exclusively for the SHA-256 algorithm, delivering elite-tier processing power for Bitcoin (BTC) mining. Released in May 2026, this next-generation mining solution achieves an extraordinary hash rate of 886 Th/s while drawing 8372W of power, resulting in an industry-leading energy efficiency of just 9.449 J/Th. The A4 Ultra Hydro redefines industrial-scale Bitcoin mining, offering one of the most efficient SHA-256 solutions available—surpassing many competitors and setting a new benchmark for hash rate density, thermal management, and operational sustainability.

At the heart of the A4 Ultra Hydro lies its advanced hydro-cooling system, which delivers superior thermal dissipation through a closed-loop liquid-cooling architecture. This sophisticated cooling solution ensures optimal operating temperatures even under sustained maximum load, dramatically reducing hardware degradation and extending operational lifespan far beyond traditional air-cooled systems. The system operates at an astonishingly quiet 50dB—unprecedented for a machine delivering nearly 900 terahash of computational power—making it ideal for facilities with strict noise regulations, residential areas, or urban data centers where acoustic pollution is a primary concern. Furthermore, the waste heat can be captured and repurposed for industrial heating, greenhouse agriculture, or district heating systems, transforming operational expenses into sustainable energy assets and improving overall facility efficiency.

Engineered for enterprise-scale deployments, the A4 Ultra Hydro adopts a sleek, rack-optimized form factor, measuring 482 x 665 x 86mm (standard 2U height) and weighing 20,500g. This standardized footprint enables seamless integration into high-density 19-inch server racks, delivering extraordinary hash rate density—a single unit does the work of multiple air-cooled miners, drastically reducing physical space requirements and infrastructure costs. The unit operates on high-voltage 380V – 480V three-phase power input, reflecting its design for professional data centers and industrial mining facilities. Connectivity is facilitated through a robust Ethernet interface, guaranteeing low-latency communication and effortless integration with all major mining management platforms. Built to thrive in demanding environments, the A4 Ultra Hydro maintains flawless performance across a wide temperature range of 5 to 45°C and supports relative humidity levels between 5% and 95%.

By investing in the Bitdeer SealMiner A4 Ultra Hydro, you are securing a premier, future-proof mining asset that delivers best-in-class petahash performance with superior hydro-cooled efficiency, whisper-quiet operation, and enterprise-grade reliability. Whether you are scaling your industrial SHA-256 fleet, modernizing your data center, or establishing a high-performance operation with stringent space and noise constraints, the A4 Ultra Hydro stands as the definitive choice for operators who demand uncompromising performance, exceptional thermal management, and sustainable innovation.
