Bitmain Antminer S23 Imm. 368T/442T: Innovation in Immersion Cooling Mining in 2026

Bitmain Antminer S23 Imm. 368T/442T is advanced ASIC miner, specially designed for immersion cooling, which represents a revolution in Bitcoin mining in 2026. This unique model series, available for order in the first quarter of 2026, offers two operating modes: 368 TH/s at an energy efficiency of 11 J/T and 442 TH/s at 12 J/T in high-performance mode. Antminer S23 Imm. is ideal for professional miners and large farms where maximum performance is required at minimal operating costs, especially in conditions of increasing network complexity.

Key Features of Antminer S23 Imm. 368T/442T

  • Flexible performance: Two operating modes – 368 TH/ss with an energy efficiency of 11 J/T in normal mode and 442 TH/ss 12 J/T in high mode – allow adaptation to different mining conditions and user needs.
  • Immersion cooling with added value: The exclusive design for operation in liquid cooling systems ensures optimal temperature, reduces noise to a minimum and extends the life of the equipment. The heat generated during operation can be used for floor heating, home heating, swimming pool heating or any water heating systems, making mining a source of additional energy.
  • Advanced technologies: Equipped with the latest chips (probably 4nm or 3nm architecture), which guarantees stability and long life even during intensive use.
  • Energy saving: Energy efficiency of 11–12 J/T minimizes electricity costs, which is especially important after the halving in 2024.
  • Compactness and reliability: The expected dimensions of 400 x 195 x 290 mm and a weight of approximately 16 kg allow for easy integration into specialized immersion cooling systems.

Technical Specifications

  • Algorithm: SHA-256
  • Hash rate: 368 TH/s (normal mode) / 442 TH/s (high mode)
  • Energy efficiency: 11 J/T (368 TH/s) / 12 J/T (442 TH/s)
  • Power consumption: 4048 W (368 TH/s) / 5304 W (442 TH/s)
  • Tension: 220–277 V (compatible with immersion systems)
  • Interface: Ethernet (RJ45)
  • Operating temperature: 0°C – 45°C (in immersion environment)
  • Noise level: Minimum (depending on cooling system)
  • Guarantee: 1 year (expected from official distributors)

Why choose Antminer S23 Imm. 368T/442T?

The Antminer S23 Imm. stands out due to its optimization for immersion cooling, which reduces cooling costs and increases operating efficiency in hot climates or crowded farms. Compared to previous models (such as the S21 Pro with 15 J/T), it offers a 20-27% improvement in energy efficiency, making it ideal for long-term investments. In addition, the use of heat from mining for heating is an environmentally friendly and cost-effective solution, especially for homes or commercial buildings with water heating systems.

Information on the use of immersion cooling

Immersion cooling is an advanced technology in which the device is completely immersed in a special dielectric liquid that absorbs heat and prevents overheating. This system not only increases the reliability and lifespan of the miner, but also allows for efficient use of the generated heat. For example:

  • Floor heating: The heat can be integrated into an underfloor heating system to ensure comfort in the home.
  • Household heating: The liquid transfers heat to radiators or convectors for room heating.
  • Pool heating: Excess heat can be directed into the pool to maintain a comfortable water temperature.
  • Industrial use: Suitable for heating greenhouses, warehouses or other buildings with water heating.
    To take advantage of these benefits, a compatible immersion cooling system and professional installation are required.

Recommendations for operation

  • Use only certified immersion cooling systems compatible with Bitmain Antminer S23 Imm.
  • Ensure stable 220-277V voltage and reliable power cables for high mode operation (442 TH/s).
  • Regularly check the fluid level in the cooling system to maintain optimal performance.
  • Place the device in a dedicated space considering the requirements of immersion cooling and integration with heating systems.
