Bitmain Antminer L11 HU6 (33GH)

33 GH/s Scrypt at 5,676W and 0.172 J/MH (172 J/GH) efficiency. Bitmain's ±3 percent tolerance produces real world output between 32 and 34 GH/s. The highest output single unit Scrypt miner Bitmain produces.

The L11 HU6 combines a 2U miner with a 4U water cooling device in one assembly. Most hydro miners require external CDUs, chillers, and facility plumbing. The L11 HU6 includes the radiator, pumps, fans, and coolant. Water fill lasts approximately 2 years. This eliminates the facility CapEx typically required for hydro deployment.

50 dB from the three radiator fans, roughly 75 percent less perceived loudness than the 75 dB air cooled L11 models. Staff can work around L11 HU6 hardware without hearing protection. Air cooled L11 deployment typically requires hearing protection for extended exposure.

5,676W continuous at 0.172 J/MH efficiency. ±5 percent power tolerance produces real world draw between 5,392 and 5,960W. At 415V three phase: approximately 7.9 amps per phase.

Both are hydro cooled Scrypt miners. The L11 Hyd 2U produces 35 GH/s in a more compact chassis fitting approximately 21 units per 42U rack (735 GH/s per rack). The L11 HU6 produces 33 GH/s with integrated all in one cooling, fitting approximately 7 units per rack (231 GH/s per rack). The 2U packs more density but triples the plumbing connections and requires external facility cooling infrastructure. The 6U trades density for simplicity and integrated cooling.

Yes, simultaneously through Scrypt merged mining, along with Bellscoin (BELLS). Luckycoin, Junkcoin, and Pepecoin also merge mine at varying pool support. Combined merged mining revenue typically runs 20 to 40 percent above solo LTC at the same hashrate.

380 to 415V three phase industrial power input at approximately 7.9 amps per phase. Not available in residential or most light commercial settings. Purpose built for professional facilities with three phase distribution. Some distributor batches ship at 220 to 277V configurations, verify input voltage before deployment.

900 x 486 x 132 mm miner chassis at 18 kg per MillionMiner's specification. The 132 mm chassis height corresponds to 3U in standard rack measurement. With the 4U radiator attached, the complete assembly reaches 6U total height that the model name references. Some documentation lists combined assembly weight at approximately 50 kg including radiator and water fill.

No. The 380 to 415V three phase input is not available in residential settings. 5,676W continuous draw requires industrial electrical service. Chassis dimensions require 19 inch rack infrastructure. For quiet home Scrypt mining, the Fluminer L3 at 9.5 GH/s and 45 dB or Fluminer L1 Pro at 6 GH/s and 45 dB are appropriate options.

L9 at 17 GH/s and 0.21 J/MH. Air cooled L11 base at 20 GH/s and 0.184 J/MH, L11 Pro at 21 GH/s and 0.172 J/MH. L11 HU6 at 33 GH/s and 0.172 J/MH. The HU6 represents a 57 percent hashrate improvement over the L11 Pro through hydro cooling's ability to sustain higher chip power density. Efficiency improved approximately 18 percent over the L9.

All in one integrated hydro. Liquid to chip cooling carries heat from the BM1485 chips via closed loop coolant to the radiator. Three 8,000 RPM fans on the radiator dissipate heat to ambient air. Factory filled on delivery. No external CDU or facility plumbing required.

20 to 50 degrees Celsius ambient, 10 to 90 percent humidity. The 20 degree minimum is higher than most ASICs and reflects hydro cooling's need for coolant to stay above condensation dew points. Cold climate deployments require facility heating. Maximum 50 degrees Celsius ambient is higher than typical ASICs because hydro cooling handles peak chip thermal load independently of ambient air.

Four step setup. Verify 380 to 415V three phase service capable of 5,676W continuous. Connect PSU, confirm water fill on radiator assembly. Connect Ethernet. Find miner IP, open web interface, configure Scrypt merged mining pool URL and LTC/DOGE/BELLS wallet addresses. Change default credentials immediately. Verify hashrate reaches 32+ GH/s within 10 minutes.

Major Scrypt merged mining pools accept L11 HU6 hashrate including F2Pool, Poolin, ViaBTC, Prohashing, and Litecoinpool. Pool fees typically 0.5 to 2 percent. Verify Bellscoin support before deployment since not all Scrypt pools have added BELLS.

Yes at managed facilities with three phase power and ambient cooling capacity. The 380 to 415V input and 5,676W draw align with industrial hosting infrastructure. Contact MillionMiner for hosting rate tiers and availability.

Bitmain specifies approximately 2 years of continuous operation between water replacements. The closed loop is factory sealed. Periodic visual inspection of coolant level, radiator cleanliness, and fan operation recommended. Dust accumulation reduces thermal transfer efficiency over time.

Third party Scrypt firmware support is less mature than SHA-256. Most L11 HU6 operators run stock Bitmain firmware. Some BraiinsOS style tuning has targeted earlier Scrypt hardware but L11 HU6 specific deployment is minimal.

Bitdeer DL1 Air at 25 GH/s, 3,725W, and 149 J/GH delivers approximately 13 percent better efficiency per gigahash than the L11 HU6. The L11 HU6 delivers 32 percent more hashrate per unit with hydro cooling acoustic advantage and Bitmain's mature firmware ecosystem. Operators prioritizing hashrate density and Bitmain tooling choose the L11 HU6. Operators prioritizing efficiency per gigahash on air cooling choose the DL1 Air.

Pro factors: highest output single unit Scrypt miner available, integrated cooling eliminates hydro facility CapEx barriers, 50 dB acoustic advantage, mature Bitmain ecosystem, merged mining revenue across LTC/DOGE/BELLS. Con factors: three phase industrial voltage excludes most non industrial facilities, water maintenance every approximately 2 years, secondary market narrower than air cooled hardware. For industrial facilities with three phase power and dense Scrypt deployment plans, the L11 HU6 delivers leading hashrate and operating economics.

For algorithm diversification: Antminer S21 XP (270 TH/s), S23 (318 TH/s), or S23E Hyd 2U (865 TH/s) cover SHA-256 Bitcoin with similar three phase hydro deployment. Antminer KS7 (45 TH/s) covers Kaspa KHeavyHash. Within Bitmain's Scrypt family: air cooled L11 Pro (21 GH/s) and L11 base (20 GH/s) for facilities without hydro infrastructure, L11 Hyd 2U (35 GH/s) for higher density hydro deployment. For quiet Scrypt exposure on separate infrastructure: Fluminer L3 (9.5 GH/s, 45 dB) or Fluminer L1 Pro (6 GH/s, 45 dB). Bitdeer SEALMINER DL1 Air (25 GH/s) provides vendor diversification with better efficiency per gigahash. MillionMiner's ASIC hosting service covers turnkey L11 HU6 deployment without facility CapEx.
