Bitmain Antminer S23 Immersion (442Th/s)

The Bitmain Antminer S23 Immersion (442Th) is a revolutionary oil-immersion cooled ASIC miner engineered exclusively for the SHA-256 algorithm, delivering elite-tier processing power for Bitcoin (BTC) mining. Released in January 2026, this next-generation immersion-cooled solution achieves an impressive hash rate of 442 Th/s while drawing 5304W of power, resulting in a solid energy efficiency of 12 J/Th. The S23 Immersion represents a paradigm shift in industrial-scale Bitcoin mining, offering operators the ability to achieve extraordinary hash rate density with the enhanced thermal management, near-silent operation, and extended hardware longevity of advanced oil-immersion cooling technology.

At the heart of the S23 Immersion lies its advanced oil-immersion cooling system, which submerges the mining hardware in a thermally conductive dielectric fluid. This sophisticated cooling solution delivers superior heat dissipation, maintaining optimal operating temperatures even under sustained maximum load, while 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 442 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.

Engineered with Bitmain's legendary industrial precision and durability, the S23 Immersion features a robust, immersion-optimized chassis, measuring 293 x 236 x 364mm and weighing 17,150g. This specialized design enables seamless integration into immersion cooling tanks, delivering extraordinary hash rate density—a critical advantage in high-density data center environments where floor space is at a premium and thermal management is paramount. The unit requires high-voltage three-phase power infrastructure, 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 S23 Immersion 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 Bitmain Antminer S23 Immersion (442Th), you are securing a revolutionary, future-proof mining asset that delivers exceptional petahash performance with oil-immersion efficiency, near-silent operation, and extended hardware longevity. Whether you are scaling your industrial SHA-256 fleet, modernizing your data center with immersion cooling, or establishing a high-performance operation with stringent space, noise, and thermal constraints, the S23 Immersion stands as the definitive choice for operators who demand uncompromising performance, exceptional thermal management, and sustainable innovation.
