Bitmain Antminer L11 Hyd HU2 35G

The Bitmain Antminer L11 Hyd HU2 (also known as Antminer L11 Hyd 2U or L11HU2) is a high-performance, hydro-cooled (liquid-cooled) ASIC miner from Bitmain, released in December 2025. It’s designed for professional mining operations, targeting the Scrypt algorithm — primarily for Litecoin (LTC) and Dogecoin (DOGE), plus other compatible coins like BELLS, JKC, LKY, PEP, and more. This is the top-tier model in the L11 Hydro series, offering superior hashrate compared to the air-cooled L11 or the 33G HU6 variant.

Here are some detailed views of the Antminer L11 Hyd HU2 in its compact 2U rack-mountable design, showing the sleek black chassis, ports, and hydro-cooling fittings:

Key Specifications

• Hashrate: 35 GH/s (gigahashes per second) — some sources list up to slight overclock potential, but official is 35 GH/s
• Power Consumption: 5775 W (typical on-wall at 25–35°C)
• Efficiency: ~165 J/GH (joules per gigahash) — highly efficient for Scrypt mining
• Algorithm: Scrypt (LTC, DOGE, and merged mining compatible)
• Cooling: Hydro (liquid) cooling — requires external coolant system (antifreeze, pure water, or deionized water); inlet temp 20–50°C, pressure ≤3.5 bar
• Noise Level: ~50 dB (much quieter than air-cooled miners due to no high-speed fans)
• Dimensions: Approx. 445 × 88 × 670 mm (2U rack form factor; with packaging ~710 × 640 × 220 mm or similar)
• Weight: Net ~19.1 kg (gross higher with packaging)
• Power Input: 3-phase, 380–415 V, 50–60 Hz (industrial-grade PSU required)
• Connectivity: RJ45 Ethernet (10/100M)
• Operating Conditions: Temp 5–45°C, humidity 5–95%
• Other Features: Rack-optimized for data centers/farms; supports pool mining; easy monitoring via Bitmain interface

Features and Use Case

This is an industrial-grade miner built for large-scale operations — not suitable for home use due to its massive power draw (over 5.7 kW!), 3-phase electricity requirement, and need for a proper hydro-cooling loop (external pumps, radiators, etc.). The liquid cooling keeps it stable, reduces noise significantly, and allows higher sustained performance in dense setups. It’s ideal for merged mining LTC + DOGE (you earn both coins simultaneously on the same hashrate).

Profitability depends heavily on current LTC/DOGE prices, network difficulty, and your electricity costs. At UK rates in Loughborough (~0.25–0.30 GBP/kWh as of recent averages), daily electricity cost could exceed £30–40, so it’s only viable in low-cost power environments or with favorable coin prices. Many farms use it for its top efficiency in the Scrypt space.

Pricing and Availability

Official Bitmain shop lists it around $16,415 USD (or ~$469 per GH/s), though spot/futures pricing fluctuates — often sold out quickly. Resellers like ASIC Miner Market, CryptoMinerBros, and others offer it in the $10,000–$17,000 range depending on batch and shipping. First batches shipped late 2025, with ongoing availability in 2026.

If you’re comparing to home-friendly options (like the earlier Canaan Avalon Nano), this is a completely different league — enterprise-level power beast for serious Scrypt mining.
