Product Overview

The IceRiver AL3 15T Alephium is a commercial-grade Alephium (ALPH) ASIC miner from IceRiver, delivering 15 terahashes per second on the Blake3 algorithm. IceRiver has become one of the leading dedicated ASIC manufacturers for Alephium, competing directly with Bitmain’s AL1 series in the high-performance Alephium mining segment.

Alephium (ALPH) uses the Blake3 hashing algorithm as part of its Proof of Less Work consensus mechanism. The IceRiver AL3 15T is positioned at the top of IceRiver’s Alephium ASIC lineup in the AL3 series, offering operators high single-unit output with efficient power consumption. IceRiver has built a strong reputation in the Kaspa mining community with their KS-series products, and brings the same engineering approach to Alephium mining hardware.

For South African operators, the IceRiver AL3 15T offers an alternative to Bitmain’s AL1 for commercial Alephium mining, with IceRiver’s own firmware and support ecosystem. Its 1350W power draw — identical to the Bitmain AL1 — keeps electrical infrastructure requirements manageable relative to commercial Bitcoin miners.

Key Features

• 15 TH/s hashrate: High-output Alephium Blake3 mining from IceRiver’s flagship AL3 series, providing strong ALPH pool contribution per deployed unit.
• ~1350W power consumption: At approximately 1350W, the AL3 15T matches the efficiency class of the Bitmain AL1 15.6T, making it one of the more power-accessible commercial ASIC miners on this site.
• Blake3 algorithm: Dedicated to Alephium (ALPH) mining on the Blake3 algorithm. Not compatible with SHA-256 (Bitcoin), kHeavyHash (Kaspa), or other algorithm networks.
• Air-cooled dual fan design: Standard industrial ASIC enclosure with dual fans. Compatible with standard mining rack deployment without specialist cooling infrastructure.
• IceRiver Alephium ecosystem: IceRiver provides dedicated ASIC mining hardware across the KS (Kaspa) and AL (Alephium) product families. Operators familiar with IceRiver’s KS-series products will find the AL3 management interface consistent.
• Ethernet (RJ-45) connectivity: Wired network connection for pool communication. Web-based configuration interface for pool setup and monitoring.
• Competitive with Bitmain AL1: At 15 TH/s vs Bitmain’s 15.6 TH/s, the IceRiver AL3 15T is directly competitive with the Antminer AL1, offering operators a choice between manufacturer ecosystems at similar performance levels.

Power & Installation Notes

South Africa’s 230V/50Hz supply is within the IceRiver AL3 15T’s 200–240V input range. No voltage converter is required for South African installations.

At approximately 1350W, the AL3 15T is one of the more power-accessible commercial ASIC miners available. A dedicated 16A circuit is sufficient for single-unit operation with comfortable headroom (the circuit is safely rated to ~2944W at 80% load). A registered electrician should still be engaged for the dedicated circuit installation to ensure safe, properly protected operation.

Load shedding planning: at 1.35 kW, a 5kWh home battery can run the AL3 for over 3.7 hours, and a 10kWh battery for over 7 hours. This makes it feasible to run through most scheduled South African load shedding stages without a generator, though this depends on the specific stage duration and battery state.

Ventilation requirements are standard for commercial ASICs: clear airflow at inlet and exhaust fan faces, ambient temperature below 40°C. Normal mining room air extraction is sufficient.

Electricity Cost Context — South Africa

Running the IceRiver AL3 15T at 1350W continuously consumes approximately 32.4 kWh per day, or roughly 972 kWh per month. At R2.80/kWh (reference residential tariff — municipal rates vary), the estimated monthly electricity cost is approximately R2 722 per month.

Calculation: (1350 ÷ 1000) × 24 × 30 × R2.80 = ~R2 722/month.

At approximately R2 722 per month, the IceRiver AL3 15T has a significantly lower operating cost than commercial Bitcoin miners. This makes it more accessible for South African operators at standard residential tariffs, though profitability still depends on ALPH price and network difficulty. This is a cost estimate only.

Ideal Use Cases

• Commercial Alephium mining operations: Operators wanting high per-unit ALPH output in an industrial form factor with IceRiver’s dedicated Alephium hardware ecosystem.
• IceRiver ecosystem operators: Miners already running IceRiver KS-series Kaspa miners who want to add Alephium exposure within the same manufacturer’s product range and management framework.
• Operators evaluating Bitmain vs IceRiver: A direct comparison point against the Bitmain Antminer AL1 15.6T for operators choosing between manufacturer ecosystems at similar performance levels.
• Lower power budget commercial mining: At 1350W, the AL3 makes commercial-scale Alephium mining accessible without the higher electrical infrastructure requirements of Bitcoin or ETC miners.
• Diversification from BTC or KAS mining: Operators who want to allocate mining capacity to Alephium’s Blake3 network as a complement to SHA-256 or kHeavyHash operations.

Frequently Asked Questions

Does the IceRiver AL3 15T work on South African power?
Yes. SA’s 230V/50Hz supply is within the AL3’s input range. A dedicated 16A circuit from a registered electrician is recommended for safe single-unit operation.

How does the IceRiver AL3 15T compare to the Bitmain Antminer AL1 15.6T?
Both deliver approximately 15 TH/s of Alephium Blake3 hashrate at ~1350W. The Bitmain AL1 edges ahead at 15.6 TH/s vs 15 TH/s. Choice depends on manufacturer preference, firmware ecosystem, and unit availability. See: Bitmain Antminer AL1 15.6T Alephium.

What Alephium mining pools are compatible with the IceRiver AL3?
All standard Alephium Stratum-protocol pools work with IceRiver miners. Popular ALPH pools include Herominers, K1Pool, and Woolypooly. Configure via the miner’s web interface.

How does the AL3 differ from smaller Alephium home miners?
The AL3 15T is a commercial-scale ASIC. For home Alephium mining with lower power and noise, the Goldshell AL Box (360 GH/s at 240W) is better suited to residential use. The AL3 is designed for dedicated mining rooms or farms.

Can I mine Kaspa with the IceRiver AL3?
No. The AL3 is a Blake3 ASIC and mines Alephium (ALPH) only. For Kaspa mining, see IceRiver’s KS-series miners.
