Bitmain Antminer L11 Hyd 2U (35GH)

The L11 Hyd 2U produces 35 GH/s of Scrypt hashrate at 5,775W continuous power draw and 0.165 J/MH efficiency (equivalently 165 J/GH). Released December 2025 as Bitmain's latest generation hydro cooled Scrypt silicon in the compact 2U form factor. The 35 GH/s figure represents the highest Scrypt hashrate per rack unit currently available from any manufacturer, making the L11 Hyd 2U the density leader for Scrypt mining in early 2026.

Same generation silicon, different chassis form factor. L11 Hyd 2U: 35 GH/s per unit at 5,775W in 2U. L11 HU6 (3U): similar per unit performance but in 3U rack mount. Critical difference is rack density. A 42U rack holds 21 L11 Hyd 2U units producing 735 GH/s aggregate, versus 7 L11 HU6 units producing roughly 231 GH/s aggregate. The 2U variant delivers more than three times the Scrypt hashrate per rack of floor space. Trade off: three times more water connections, power cords, and individual units to maintain per rack. Optimize for density with 2U, or for per unit simplicity with 3U.

Two scenarios favor high density hardware. First: facilities with limited physical floor space where every square meter of real estate carries meaningful cost, common in urban colocation facilities or data centers operating under space constraints. Second: facilities scaling Scrypt operations within existing electrical capacity ceilings where adding more racks means repurposing existing space rather than building new facility. The L11 Hyd 2U extracts maximum Scrypt hashrate from available floor space. For operations with unlimited floor space and unlimited electrical capacity, density advantages matter less.

All Scrypt proof of work cryptocurrencies. Primary targets through merged mining: Litecoin (LTC) with the largest Scrypt network, and Dogecoin (DOGE) with strong retail interest. Merged mining means one fleet simultaneously contributes hashrate to both networks without splitting output. Secondary Scrypt coins supported through major pools: Bellscoin (BEL), PepeCoin (PEP), DigiByte Scrypt chain (DGB), Luckycoin (LKY), Catcoin (CAT), DingoCoin (DINGO), Auroracoin (AUR), GoldCoin (GLC), Junkcoin (JKC), and smaller forks. Revenue from all simultaneously mined chains streams into the same wallet addresses. Quai (QUAI) at 722 QUAI daily per current ASIC Miner Value data represents emerging Scrypt compatible chain activity.

Merged mining allows identical hashing work to qualify for block rewards on multiple compatible networks simultaneously. For Scrypt, this means a single fleet submitting hashes to a merged mining pool earns LTC, DOGE, BEL, and other Scrypt rewards without splitting computational effort. Economic effect: Dogecoin rewards are effectively free additional revenue on top of Litecoin mining, because the same work qualifies for both. Most operators running Scrypt hardware treat DOGE rewards as bonus yield on primary LTC mining operations. Pool configuration automatically handles the merged mining protocol through supporting pools like F2Pool, ViaBTC, AntPool, and EMCD.

380 to 480V three phase commercial or industrial power. At 415V three phase: approximately 13.5 amps per phase continuous draw at 5,775W. At 480V three phase: approximately 11.7 amps per phase. Fits within standard 20 amp commercial breakers with headroom. Not suitable for standard residential or small commercial electrical systems. European, Middle Eastern, and industrial Asian facilities at 380 to 415V three phase have direct deployment paths. North American industrial facilities at 480V three phase also deploy directly.

Closed loop water circulation with standard industrial components. Required: circulation pumps sized for total fleet flow rate, standard plumbing fittings, water glycol coolant mixture, external heat rejection through dry coolers or water to water heat exchangers, and inline filtration. Coolant volume scales roughly 2 to 4 liters per unit plus system reservoir capacity. Each L11 Hyd 2U adds approximately 19,715 BTU per hour of thermal load. A fully loaded 42U rack producing 121 kW thermal output requires roughly 413,300 BTU per hour heat rejection capacity. Uses standard data center cooling equipment from any industrial supplier.

Yes. The 2U form factor is identical between generations, with same water connector geometry, same chassis dimensions, same rack mounting hardware, and same water manifold compatibility. Mixed rack deployment allows facilities to upgrade gradually from L9 (27 GH/s) to L11 (35 GH/s) generation hardware as capital becomes available or as L9 warranty periods expire. No infrastructure changes required when introducing L11 units into existing L9 hydro installations. Fleet management through standard Antminer firmware handles mixed generation deployment transparently.

Highly electricity rate dependent. MillionMiner's $0.08 per kWh onsite calculator shows $22.79 daily revenue, $11.09 electricity, $11.70 net daily profit per unit. ASIC Miner Value data at AED 0.53 per kWh (approximately $0.144 per kWh residential rates) shows negative daily margins reflecting current Scrypt market conditions at consumer electricity pricing. At $0.04 per kWh negotiated industrial rates: $5.54 daily electricity, netting roughly $17 daily profit per unit. At $0.07 per kWh typical industrial rates: $9.71 daily electricity, netting roughly $13 daily. Economic viability requires industrial electricity below $0.10 per kWh for reliably positive returns. Scrypt profitability varies significantly with LTC and DOGE price movements.

50 dB for the L11 Hyd 2U versus 75 dB typical for air cooled Scrypt miners. The 25 dB gap represents roughly half the perceived sound intensity to human ears. Practical implications: multi tenant colocation facilities can deploy L11 Hyd 2U hardware without disrupting neighboring tenant operations, data centers with mixed workloads avoid acoustic interference with staff areas, research facilities and test environments can operate mining hardware alongside sensitive equipment, and operations where staff work near hardware for extended periods reduce occupational noise exposure significantly.

Not practically. Despite the quieter 50 dB acoustic profile, the L11 Hyd 2U requires 380 to 480V three phase industrial power unavailable in residential settings, water cooling loop infrastructure with pumps and heat rejection capacity, and professional installation for both electrical service and plumbing. Home mining hardware caps at around 3,500W per unit on standard 240V single phase circuits. For residential Scrypt mining, air cooled models like smaller Antminer L series units or the L9 are more appropriate product matches. The L11 Hyd 2U is strictly industrial hardware for professional mining facilities.

Industrial deployment with three phase power and water cooling infrastructure. Step one: install three phase 380 to 480V electrical service. Step two: install and commission water cooling loop including pumps, plumbing, dry coolers, and initial coolant fill. Step three: rack mount L11 Hyd 2U units in standard 19 inch racks and connect water inlet/outlet fittings to your manifold system. Verify zero leaks before energizing. Step four: connect PSU power and Ethernet management. Step five: power on, allow coolant flow to stabilize, find each miner IP through DHCP, configure Scrypt merged mining pool URL and LTC/DOGE wallet addresses through Antminer web interface, verify hashrate reaches 34 to 35 GH/s within 10 to 15 minutes per unit.

Major Scrypt merged mining pools include F2Pool (26.7 percent Scrypt network share), ViaBTC (29.0 percent with merged mining support), AntPool (17.8 percent), and EMCD (6.3 percent). All support simultaneous LTC and DOGE mining plus secondary Scrypt chain rewards. Pool fee comparison: F2Pool PPLNS at 4 percent or PPS at 4 percent, ViaBTC PPLNS at 2 percent, AntPool PPS at 3 percent, EMCD PPLNS at 1.5 percent (with 10 percent discount via AMV10 code per ASIC Miner Value listing). For fleet deployments above 1 PH/s Scrypt (equivalent to 28+ L11 Hyd 2U units), negotiated pool fees below standard rates typically become available.

Water cooling maintenance. Weekly visual inspection of all fittings for leaks or corrosion. Monthly coolant quality testing (pH within spec, particulate levels minimal). Every 12 to 24 months full coolant replacement depending on fluid chemistry. Quarterly pump and dry cooler inspection. Inline filter replacement when pressure differential exceeds specification. Higher unit count per rack (21 units versus 7 in the 3U variant) increases cumulative maintenance cycles per rack but individual unit failures have smaller fleet impact. Budget 3 to 5 percent of acquisition cost annually per unit for coolant, filtration, and spare parts.

CapEx additions beyond miner acquisition: three phase electrical service installation ($5,000 to $20,000 per facility), water cooling loop and pumps ($5,000 to $20,000 per rack), racks and cabling ($1,500 to $4,000 per rack). Annual OpEx per unit at 5.775 kW: electricity at $4,047 at $0.08 per kWh, $3,540 at $0.07 per kWh industrial rates, or $2,023 at $0.04 per kWh negotiated industrial rates. Coolant maintenance: $100 to $300 per unit annually. Spare parts: $200 to $400 annually per unit. 3 year TCO per unit at $0.07 per kWh: approximately $13,000 hardware and infrastructure plus $10,620 electricity.

Yes. MillionMiner operates managed hosting facilities with three phase industrial power and water cooling infrastructure capable of supporting L11 Hyd 2U deployments. Hosted deployment eliminates facility infrastructure CapEx. Professional hosting at negotiated industrial rates often beats self hosting for Scrypt miners without access to industrial electricity below $0.08 per kWh, because Scrypt profitability margins are tight at standard commercial rates.

Bitmain's factory warranty on the complete machine covers manufacturing defects and hardware failures under normal operation within specified environmental ranges. Warranty exclusions include damage from coolant quality neglect, leaks caused by improper fitting installation, physical damage during cooling loop maintenance, power surge damage from inadequate electrical protection, and operation outside the 5 to 45 degree Celsius range. Document coolant testing schedule and maintenance logs to protect warranty coverage. MillionMiner routes claims through direct Bitmain channels for faster resolution than secondary market purchases provide.

Standard Antminer firmware provides the same web interface, pool configuration format, and management API as other Bitmain miners. Fleet management tools including Foreman, Awesome Miner, Hive OS, and Braiins OS+ discover L11 Hyd 2U units automatically through network scanning. Additional monitoring metrics for hydro operation (coolant flow rate, inlet/outlet temperatures) appear in hydro specific dashboards. Mixed brand and cooling type fleets handle through unified dashboards, with Scrypt specific metrics tracked alongside SHA-256 or Equihash operations if running multi algorithm mining facilities.

Depends on electricity rate and LTC/DOGE price outlook. Current economics per MillionMiner onsite calculator show $11.70 net daily profit at $0.08 per kWh, so industrial facilities with rates below $0.10 per kWh maintain healthy margins. ASIC Miner Value data at consumer residential rates shows negative margins, indicating Scrypt mining at residential electricity is not economically viable at current LTC/DOGE prices. Dogecoin retail interest and Litecoin network effects continue to support Scrypt mining economics but margins have compressed over multiple years as network difficulty has grown faster than coin prices. Model conservatively against current network conditions rather than assuming favorable future price movements.

Within Scrypt: the previous generation L9 Hyd 2U at 27 GH/s (same 2U chassis, compatible with shared water manifolds), air cooled L11 Pro for facilities without hydro infrastructure, and older L7 series hardware at budget tier pricing. Cross algorithm diversification options: Antminer S21 XP at 270 TH/s or Whatsminer M70S+ at 244 TH/s for SHA-256 Bitcoin mining, Antminer KS7 at 45 TH/s for KHeavyHash Kaspa mining, Antminer Z15 at 420 kSol/s for Equihash Zcash mining, Goldshell HS5 series for Handshake (HNS) mining. For multi algorithm fleet diversification, the L11 Hyd 2U represents the Scrypt component of a balanced portfolio. MillionMiner's ASIC hosting service accepts L11 Hyd 2U units at negotiated industrial electricity rates.
