#Hardware #Enterprise #Bitdeer
Bitdeer SealMiner is the fleet to buy when efficiency per watt matters more than brand familiarity: the SealMiner A4 Ultra Hydro runs at 9.45 J/TH, the second-most-efficient hydro miner in the MineForgeX catalog behind only the Antminer S23 XP Hyd at 8.9 J/TH, and the air-cooled A4 Pro Air leads all air-cooled models at 10.9 J/TH. This guide compares all seven SealMiner models MineForgeX stocks — five SHA-256 miners for Bitcoin and two Scrypt miners for Litecoin and Dogecoin — on verified hashrate, power, efficiency and price, so a fleet plan can be priced before it is ordered.
Bitdeer SealMiner at a Glance
Bitdeer builds its own silicon and its own miners, and the SealMiner line is the result: the A4 range was announced in April 2026, sampled in the second quarter and shipped in volume from the third, and Bitdeer broke ground in July 2026 on a manufacturing and assembly facility in Sparks, Nevada, its first in the United States. The range splits cleanly into three groups: the A4 hydro and air flagships, the A3 workhorses, and the DL1 Scrypt pair for Litecoin and Dogecoin.
- Seven models in the MineForgeX catalog: five SHA-256 Bitcoin miners and two Scrypt miners.
- Efficiency from 9.45 J/TH (A4 Ultra Hydro) to 12.5 J/TH (A3 range) on the Bitcoin side.
- Hydro models run at 50 dB in a 2U rack form factor on 380 to 415 V three-phase power; air models run at 75 dB on 200 to 240 V single-phase power.
- Every model carries a 12-month warranty; the A3 pair is in stock for spot delivery, the A4 and DL1 models are on limited allocation.
The SHA-256 Fleet Ladder: Five Models Compared
The five Bitcoin miners span 290 TH/s to 886 TH/s, and the ladder is really two ranges: the A4 pair at 9.45 to 10.9 J/TH and the A3 pair at 12.5 J/TH. The A3 models cost more per terahash to run, so the choice is between the A4's efficiency premium and the A3's lower ticket price and immediate availability.
| Model | Hashrate | Power | Efficiency | Price | Cost per TH/s |
|---|---|---|---|---|---|
| Bitdeer SealMiner A4 Ultra Hydro | 886 TH/s | 8,373 W | 9.45 J/TH | $10,600 | $11.96 |
| Bitdeer SealMiner A4 Pro Hydro | 680 TH/s | 7,412 W | 10.9 J/TH | $8,699 | $12.79 |
| Bitdeer SealMiner A4 Pro Air | 336 TH/s | 3,662 W | 10.9 J/TH | $6,750 | $20.09 |
| Bitdeer SealMiner A3 Pro Hydro | 660 TH/s | 8,250 W | 12.5 J/TH | $9,970 | $15.11 |
| Bitdeer SealMiner A3 Pro Air | 290 TH/s | 3,625 W | 12.5 J/TH | $4,490 | $15.48 |
The efficiency leader: A4 Ultra Hydro
The A4 Ultra Hydro is the fleet standard for SealMiner: 886 TH/s at 8,373 W and 9.45 J/TH, priced at $10,600, or $11.96 per TH/s — the lowest cost per terahash in the range and the second-best hydro efficiency in the catalog. It is a 2U hydro unit at 50 dB on 380 to 415 V three-phase power, with a 12-month warranty and limited allocation. The full listing is on the [SealMiner A4 Ultra Hydro product page](/product/bitdeer-sealminer-a4-ultra-hydro-886t).
The mid-range: A4 Pro Hydro and A4 Pro Air
The A4 Pro Hydro delivers 680 TH/s at 10.9 J/TH for $8,699, or $12.79 per TH/s, in the same 2U hydro form factor at 50 dB. The A4 Pro Air delivers 336 TH/s at the same 10.9 J/TH for $6,750, or $20.09 per TH/s, on standard 200 to 240 V single-phase power at 75 dB. The Hydro is the better buy on cost per terahash; the Air is the pick where there is no hydro loop and no three-phase supply, and at 10.9 J/TH it is the most efficient air-cooled miner in the catalog.
The value range: A3 Pro Hydro and A3 Pro Air
The A3 pair runs Bitdeer's SEAL02 silicon at 12.5 J/TH. The A3 Pro Air delivers 290 TH/s for $4,490, or $15.48 per TH/s, and the A3 Pro Hydro delivers 660 TH/s for $9,970, or $15.11 per TH/s. Both are in stock for spot delivery, which the A4 models are not. Note the pricing quirk: the A3 Pro Hydro costs more than the A4 Pro Hydro while using more power per terahash, so compare allocation and delivery dates before ordering either. Buy the A3 pair for immediate deployment and a low ticket price, not for operating cost.
Scrypt on the Same Racks: SealMiner DL1
The DL1 pair mines Litecoin and Dogecoin on Scrypt, and both models share the same 149 J/GH efficiency — the choice is cooling and scale, not efficiency. Do not compare the 149 J/GH figure with SHA-256 J/TH: the algorithms do different work per hash, and the units are not interchangeable.
| Model | Hashrate | Power | Efficiency | Price | Cost per GH/s |
|---|---|---|---|---|---|
| Bitdeer SealMiner DL1 Hydro | 52.5 GH/s | 7,823 W | 149 J/GH | $12,900 | $245.71 |
| Bitdeer SealMiner DL1 Air | 25 GH/s | 3,725 W | 149 J/GH | $9,500 | $380.00 |
DL1 Hydro: the Scrypt flagship
The DL1 Hydro delivers 52.5 GH/s at 7,823 W for $12,900, or $245.71 per GH/s, in a 2U hydro form factor on 380 to 415 V three-phase power, with a 12-month warranty and limited allocation. At the same 149 J/GH it costs about 35 percent less per GH/s than the Air model, so hydro is the buy wherever a liquid loop exists.
DL1 Air: Scrypt without a liquid loop
The DL1 Air delivers 25 GH/s at 3,725 W for $9,500, or $380.00 per GH/s, on standard 200 to 240 V single-phase power, with a 12-month warranty and limited allocation. Both DL1 models run at 75 dB, so even the hydro unit needs a dedicated hall — unlike the SHA-256 hydro models, which run at 50 dB.
Power, Noise and Site Planning
Daily electricity is power multiplied by 24 hours: at $0.08 per kWh an A4 Ultra Hydro uses 200.95 kWh per day and costs $16.08, while an A3 Pro Air uses 87.00 kWh and costs $6.96. Per terahash the gap is wider, because the A4 Ultra Hydro's 9.45 J/TH costs $0.0181 per TH/s per day against $0.0240 for the A3 pair's 12.5 J/TH. These are electricity costs only: revenue depends on the coin price and network difficulty, which move daily, so no income or payback figure is stated here. Model revenue against these costs with the [mining calculator](/calculator) at your own power price.
| Model | J/TH | Daily cost per TH/s at $0.08/kWh | Daily electricity per unit at $0.08/kWh |
|---|---|---|---|
| SealMiner A4 Ultra Hydro | 9.45 | $0.0181 | $16.08 |
| SealMiner A4 Pro Hydro | 10.9 | $0.0209 | $14.23 |
| SealMiner A4 Pro Air | 10.9 | $0.0209 | $7.03 |
| SealMiner A3 Pro Hydro | 12.5 | $0.0240 | $15.84 |
| SealMiner A3 Pro Air | 12.5 | $0.0240 | $6.96 |
A 10 PH/s fleet built from the A4 Ultra Hydro needs 12 units (10,632 TH/s), drawing 100.5 kW and costing $127,200. The same capacity from the A4 Pro Hydro needs 15 units (10,200 TH/s), drawing 111.2 kW and costing $130,485. From the A4 Pro Air it needs 30 units (10,080 TH/s), drawing 109.9 kW and costing $202,500. From the A3 Pro Air it needs 35 units (10,150 TH/s), drawing 126.9 kW and costing $157,150. The efficiency spread is worth real money: at $0.08 per kWh the A3 fleet costs $58.56 more per day than the A4 Ultra Hydro fleet for the same 10 PH/s, or about $21,374 over a year. Noise decides the hall as well: the hydro models run at 50 dB and the air models at 75 dB, and the hydro models need a 380 to 415 V three-phase supply plus a coolant loop. The [turnkey infrastructure](/infrastructure) options cover containers, immersion tanks and dry coolers for the fleet side of the build.
Choosing a SealMiner Fleet for Your Site
Start from cooling, then pick the model. Where a hydro loop and three-phase power exist, the A4 Ultra Hydro is the pick on both efficiency and cost per terahash. Where there is no liquid cooling, the A4 Pro Air is the most efficient air-cooled miner in the catalog. Where deployment cannot wait, the A3 pair is in stock for spot delivery. Scrypt capacity belongs after the Bitcoin core is sized, and the DL1 Hydro is the buy wherever a liquid loop exists.
Who this guide is for, and who it is not for
This guide is for data centre operators, institutional buyers and fleet owners adding Bitdeer capacity. It is not for buyers choosing between algorithms on efficiency alone, and it is not a revenue forecast: no figure here promises income.
Which SealMiner is the most efficient?
The SealMiner A4 Ultra Hydro at 9.45 J/TH, followed by the A4 Pro Hydro and A4 Pro Air at 10.9 J/TH and the A3 pair at 12.5 J/TH.
Which SealMiner is the cheapest per TH/s?
The A4 Ultra Hydro at $11.96 per TH/s, followed by the A4 Pro Hydro at $12.79 and the A3 Pro Hydro at $15.11.
Can SealMiner air and hydro models share a site?
Yes, but they need different power: hydro models need 380 to 415 V three-phase power and a coolant loop, while air models run on 200 to 240 V single-phase power. Plan the electrical design before ordering a mixed fleet.
What should I confirm before ordering?
Hashrate and allocation for the model you want, your site's power type and capacity, the cooling and noise design, warranty length, and freight terms to your destination. One clear next step: shortlist from the tables above, run each candidate at your power price, and request a quote stating hashrate, power price, cooling status and destination.
