The Bitmain Antminer L11 HU6 offers a fundamentally different approach to Scrypt mining. Rather than requiring connection to a facility-wide cooling loop, this self-contained hydro miner ships with its own integrated radiator, making liquid cooling accessible for sites without centralized hydro infrastructure. With a hashrate of 33 GH/s and efficiency of 172 J/GH, it delivers the highest single-unit Scrypt output Bitmain currently produces. The unit simultaneously mines Litecoin (LTC), Dogecoin (DOGE), and Bellscoin (BELLS) through merged mining, typically generating 20 to 40 percent higher combined revenue than solo LTC mining.
Released in January 2026, the L11 HU6 ranks fifth in efficiency among Scrypt miners, placing it ahead of the air-cooled L11 Pro (21 GH/s) and the base L11 (20 GH/s) in the product hierarchy. Its 3U rack format combines a 2U miner chassis with a 4U water cooling device, removing the need for external CDU infrastructure. This all-in-one engineering enables operation at just 50 dB, a substantial reduction from typical air-cooled Scrypt miners.
The L11 HU6 represents a deliberate shift from shared-liquid infrastructure to self-contained hydro cooling. Each unit ships with its own radiator, enabling liquid-cooled Scrypt mining without requiring a facility-wide coolant loop or central distribution unit. This design makes hydro mining accessible to operators who lack the capital or infrastructure for large-scale liquid cooling systems.
The miner’s 3U chassis integrates both the mining hardware and the cooling system, simplifying deployment and reducing the points of failure associated with external cooling infrastructure. The included power supply requires 380-415V three-phase input, consistent with industrial data center standards.

The L11 HU6 is optimized for the Scrypt algorithm, which powers multiple cryptocurrencies:
Litecoin (LTC) – Primary coin
Dogecoin (DOGE) – Merge-mined alongside LTC without additional power consumption
Bellscoin (BELLS) – Additional merged mining coin
Other Scrypt coins: BEL, JKC, LKY, PEP, DINGO, SHIC, CRC
The merged mining capability is a key advantage: while mining Litecoin, the miner simultaneously earns Dogecoin and Bellscoin through the same hashing work, effectively increasing revenue without increasing power draw.
Self-Contained Hydro Cooling: Ships with its own radiator, eliminating the need for facility-wide liquid cooling infrastructure.
Top-Tier Efficiency: 172 J/GH ranks fifth among 44 Scrypt miners, delivering strong returns at competitive electricity rates.
Quiet Operation: 50 dB is a substantial improvement over traditional air-cooled Scrypt miners, making it more suitable for sites with noise constraints.
Merged Mining Advantage: Simultaneously mines LTC, DOGE, and BELLS from the same work, typically generating 20-40% more combined revenue than solo LTC mining.
Proven Manufacturer: Bitmain remains the largest ASIC manufacturer by shipment volume, with mature firmware and established RMA processes.
Industrial Power Requirements: Requires 380-480V three-phase power—not suitable for residential or small commercial facilities.
Hydro Infrastructure: While self-contained, the unit still requires proper coolant management and heat rejection planning.
Premium Pricing: Priced at approximately $17,995 per unit, representing a significant capital investment.
Fleet Economics: For large-scale deployments, the self-contained design may be less cost-effective than shared-liquid infrastructure that serves multiple units.
Low Electricity Rates: Best operated with electricity costs below $0.08/kWh for optimal ROI.
Industrial Facility: Requires 380-480V three-phase power and proper heat rejection capabilities.
Merged Mining Optimization: Ensure mining pool configuration supports combined LTC+DOGE+BELLS rewards to maximize revenue.

Bitmain is the world's leading ASIC miner manufacturer, and the Antminer lineup remains the benchmark every competing brand gets measured against — covering Bitcoin (SHA-256), Litecoin and Dogecoin (Scrypt), and Zcash (Equihash) mining across both current-generation and value-priced secondhand hardware.
For miners prioritizing maximum efficiency right now, Bitmain's newest releases - including the Antminer S21 series for Bitcoin and the Antminer L9 for Litecoin/Dogecoin - represent the current leading edge in hashrate-per-watt performance, giving serious operations the lowest operational cost per unit mined of any generation Bitmain has released to date. For miners working with a tighter budget, our tested secondhand Antminer units (L3++, L3+, Z15, S17 Pro, and more) deliver the same reliable Bitmain engineering at a fraction of new-unit pricing - each one tested and backed by warranty support before it ships.
