Description
Antminer L11 Hydro 2U 35GH/s Scrypt Miner
The Antminer L11 Hydro 2U is a professional Scrypt ASIC miner manufactured by Bitmain for large Litecoin and Dogecoin mining farms, hydro-cooled data centres and high-density rack installations. Officially identified by Bitmain as the Litecoin Miner L11 HU2, this advanced machine delivers a typical hashrate of 35GH/s while consuming approximately 5,775W.
With an official power efficiency of 165J/GH, equivalent to approximately 0.165J/MH, the Antminer L11 Hydro 2U provides substantially more Scrypt output than older air-cooled Litecoin miners. Its compact 2U form allows professional operators to install significant Scrypt hashrate in standardized rack infrastructure while managing heat through a centralized liquid-cooling loop.
The Antminer L11 Hydro 2U can mine Litecoin, Dogecoin and other compatible Scrypt cryptocurrencies. Through auxiliary proof-of-work merged mining, many pools allow operators to mine Litecoin and Dogecoin simultaneously without dividing the machine’s hashrate between the two networks.
This is not a household plug-and-play miner. The Antminer L11 Hydro 2U requires 380–415V three-phase electricity, an approved hydro-cooling system, RJ45 Ethernet, suitable rack infrastructure, external heat rejection and professional installation.

Specification note: Bitmain officially lists the Antminer L11 Hydro 2U at 35GH/s, 5,775W and 165J/GH. Hashrate, power and efficiency may vary within factory tolerance and according to coolant temperature, electrical conditions, firmware and operating mode.
The original description incorrectly stated that the miner used four high-speed fans. A hydro-cooled 2U miner depends primarily on direct liquid cooling and external cooling infrastructure rather than a conventional four-fan airflow system.
Before ordering, confirm the delivered model label, batch, power connector, coolant-flow requirement, chassis measurements, firmware and warranty conditions.

Antminer L11 Hydro 2U Scrypt Mining Performance
The Antminer L11 Hydro 2U delivers a typical Scrypt hashrate of 35GH/s. This performance is intended for professional mining farms that can provide reliable three-phase electricity, continuous coolant circulation, stable Ethernet connectivity and sufficient heat-rejection capacity.
Actual accepted hashrate may vary according to pool latency, coolant temperature, firmware, input voltage, chip condition, uptime and share variance. Operators should compare the local dashboard with pool-side accepted hashrate over several hours or days.
Important performance indicators include:
- Real-time hashrate
- Long-term average hashrate
- Accepted and rejected shares
- Hashboard status
- ASIC hardware errors
- Coolant inlet temperature
- Coolant outlet temperature
- Coolant flow rate
- Coolant pressure
- Measured wall power
- Pool latency
- Ethernet uptime
A sustained reduction in Antminer L11 Hydro 2U output may indicate insufficient coolant circulation, excessive inlet temperature, trapped air, unstable voltage, network interruption, incorrect pool settings or a hardware fault.
Antminer L11 Hydro 2U 165J/GH Efficiency
The Antminer L11 Hydro 2U is officially rated at 165 joules per gigahash. Dividing 5,775W by 35GH/s confirms the efficiency:
5,775W ÷ 35GH/s = 165J/GH
Because one gigahash equals 1,000 megahashes, the same efficiency can be expressed as approximately 0.165J/MH.
At a continuous 5,775W load, estimated miner-only electricity consumption is:
- 138.6kWh per day
- 970.2kWh per week
- 4,158kWh per 30-day month
- 50,589kWh per year
Estimated monthly electricity costs are:
- At $0.03/kWh: approximately $124.74
- At $0.04/kWh: approximately $166.32
- At $0.05/kWh: approximately $207.90
- At $0.06/kWh: approximately $249.48
- At $0.08/kWh: approximately $332.64
- At $0.10/kWh: approximately $415.80
- At $0.15/kWh: approximately $623.70
- At $0.20/kWh: approximately $831.60
These calculations cover only the nominal mining load. Coolant pumps, heat exchangers, dry coolers, transformers, switches, routers and facility losses add to total energy consumption.
Mining profitability is not guaranteed. Litecoin and Dogecoin prices, Scrypt network difficulty, block rewards, merged-mining rewards, pool fees, electricity rates, cooling overhead, hardware cost and uptime all influence results.
Antminer L11 Hydro 2U Hydro-Cooling Requirements
The Antminer L11 Hydro 2U requires a professionally engineered liquid-cooling system. Coolant circulates through internal cold plates, absorbs heat from the ASIC hardware and transfers that energy to an external heat exchanger, dry cooler, cooling tower or heat-reuse system.
At 5,775W, the miner produces approximately 5.78kW of continuous heat. Liquid cooling moves this heat away from the electronics, but the facility must still reject or reuse it.

Mineable Coins with Antminer L11 Hydro 2U
Litecoin
Litecoin is one of the primary Scrypt cryptocurrencies mined by the Antminer L11 Hydro 2U.
Dogecoin
Dogecoin can commonly be earned alongside Litecoin through an auxiliary proof-of-work merged-mining pool.
Bitmain also lists Bells, Junkcoin, Luckycoin and PepeCoin among the supported Scrypt networks for the L11 HU2. Additional technically compatible Scrypt currencies may be mineable where suitable pools, wallets and market liquidity exist.
Before changing networks, compare:
- Mining difficulty
- Expected block rewards
- Merged-mining support
- Pool fees
- Payout thresholds
- Wallet availability
- Exchange liquidity
- Network security and development activity
For information about Litecoin mining and its Scrypt network, review the official Litecoin website. Dogecoin information is available from the official Dogecoin website.
Antminer L11 Hydro 2U Merged Mining
The Antminer L11 Hydro 2U can benefit from auxiliary proof-of-work, commonly called merged mining. This system allows a compatible pool to use the same Scrypt work to secure Litecoin and Dogecoin at the same time.
Merged mining does not mean that the 35GH/s hashrate is split between both currencies. Instead, compatible proof-of-work submissions may qualify for rewards on the primary and auxiliary chains.
The exact rewards received depend on the pool’s payment model. Some pools automatically convert or distribute auxiliary rewards, while others require separate wallet addresses or account settings.
Before choosing a merged-mining service, confirm:
- Which Scrypt currencies are included
- How auxiliary rewards are calculated
- Whether rewards are paid directly or converted
- Pool and withdrawal fees
- Minimum payout thresholds
- Required wallet addresses
- Server location and latency
- Historical uptime
Antminer L11 Hydro 2U Mining-Pool Setup
The Antminer L11 Hydro 2U connects to compatible Scrypt mining pools through its RJ45 Ethernet interface. Pool mining combines the work of many machines and distributes rewards according to submitted shares and the selected payout method.
Pool configuration normally requires:
- A Scrypt Stratum server address
- A worker name
- A pool password
- A Litecoin or account payout destination
- Dogecoin or auxiliary wallet settings where applicable
- Primary and backup servers
Before selecting a pool, compare fees, payout methods, merged-mining support, minimum withdrawals, server locations, uptime, security controls and reporting tools.
Configure secondary and tertiary pool servers where supported. This helps the Antminer L11 Hydro 2U continue operating if the primary pool server becomes unavailable.
Antminer L11 Hydro 2U Electrical Requirements
The Antminer L11 Hydro 2U requires 380–415V AC three-phase power. It must not be connected to a normal household single-phase electrical outlet.
At the nominal 5,775W load, approximate balanced three-phase current is:
- Approximately 8.78A per phase at 380V, assuming a power factor near 1
- Approximately 8.03A per phase at 415V, assuming a power factor near 1
Actual current may differ because of power factor, voltage tolerance, startup behaviour, operating mode and cable losses.
Electrical Installation Requirements
- Grounded 380–415V three-phase supply
- Correctly rated circuit breaker or fused disconnect
- Manufacturer-approved power connector and cable
- Conductors sized for continuous operation
- Overcurrent protection
- Surge protection
- Phase and voltage monitoring
- Emergency disconnect controls
- Dry electrical terminations
- Compliance with local electrical regulations
A qualified industrial electrician should approve the circuit before the Antminer L11 Hydro 2U is energized.
