Antminer S21+ Hyd.

Description

Antminer S21+ Hyd.

Are you looking for a powerful hydro-cooled Bitcoin miner designed for large-scale mining farms? The Antminer S21+ Hyd. from Bitmain is a next-generation ASIC miner built to deliver strong hashing performance with advanced liquid-cooling technology and efficient power usage.

The Antminer S21+ Hyd. operates on the SHA-256 algorithm, making it ideal for mining Bitcoin (BTC) as well as other SHA-256 cryptocurrencies such as Bitcoin Cash (BCH) and Bitcoin SV (BSV). Depending on the configuration, the miner delivers a hashrate of around 358–395 TH/s while consuming approximately 5370–5925W of power, resulting in an efficiency of about 15 J/TH.

Designed with a hydro-cooling liquid system, the miner removes heat directly from the ASIC chips through circulating coolant. This architecture allows the S21+ Hyd. to operate continuously at high performance while maintaining stable temperatures and reducing noise compared to traditional air-cooled mining hardware.

The miner typically requires 380–415V three-phase power and connects through a standard Ethernet interface for network communication and remote management. Its hydro-cooling design allows mining farms to deploy large numbers of units in dense configurations while maintaining reliable thermal control and long-term operational stability.

With up to around 395 TH/s SHA-256 hashing power, approximately 5.3–5.9 kW power consumption, and efficient liquid-cooling technology, the Antminer S21+ Hyd. provides a powerful and scalable solution for modern Bitcoin mining operations that require high performance and stable industrial-grade cooling infrastructure.
