Bitdeer SealMiner A2 Pro Hydro (500TH)

500 TH/s SHA-256 at 7,450W and 14.9 J/TH with hydro cooling on Bitdeer's proprietary SEAL01 chip. ±3 percent hashrate and ±5 percent power tolerance. Upgrades the original A2 Hyd (446 TH/s, 16.5 J/TH) with 12 percent more hashrate at 10 percent better efficiency from the same SEAL01 silicon. The "Pro" designation reflects improved chip binning and power delivery from the same first generation architecture.

A3 Pro Hydro at 660 TH/s, 8,250W, 12.5 J/TH, $10,449 (SEAL02). A2 Pro Hydro at 500 TH/s, 7,450W, 14.9 J/TH, $6,900 (SEAL01, this product). The A3 delivers 32 percent more hashrate at 16 percent better efficiency for $3,549 more. The A2 Pro Hydro produces higher daily dollar profit (+$4.30 versus +$3.56) because lower CapEx shifts the daily economics. For deployments under 26 months, the A2 Pro Hydro delivers better total return per dollar invested. For longer deployments, the A3 Pro Hydro's efficiency advantage compounds past the CapEx gap.

S21 XP Hydro at 473 TH/s, 5,676W, 12 J/TH, $6,899. A2 Pro Hydro at 500 TH/s, 7,450W, 14.9 J/TH, $6,900. Same price within $1. The A2 Pro Hydro produces 5.7 percent more hashrate but at 24 percent worse efficiency. Daily profit: A2 Pro Hydro at +$4.30 versus S21 XP Hydro at +$3.01. The A2 Pro Hydro produces more Bitcoin per day because it deploys more hashrate. The S21 XP Hydro is more electricity efficient per terahash. At $0.08 per kWh, the A2 Pro Hydro wins. At higher electricity rates the S21 XP Hydro's efficiency advantage narrows and eventually reverses the margin.

380 to 480V three phase AC. Standard commercial and industrial electrical service. Not compatible with residential single phase (110V or 240V). At 7,450W on 380V three phase, draws approximately 11.3 amps per phase. Requires a dedicated 3-phase circuit in a data center, mining container, or industrial facility. This is standard infrastructure for any hydro cooled ASIC miner.

Yes. MillionMiner calculator at $0.08 per kWh: +$4.30 daily ($18.61 revenue minus $14.30 electricity). Monthly: +$129. At $6,900 acquisition: payback approximately 54 days. At $0.07 per kWh: +$6.09 daily, payback approximately 38 days. At $0.05 per kWh: +$9.67 daily, payback approximately 24 days. Profitable at any rate below approximately $0.10 per kWh at April 2026 conditions. The daily profit is higher than the newer A3 Pro Hydro because of the $3,549 lower acquisition cost.

2U rack mount. 482 x 665 x 86 mm at 20.5 kg. Standard 19 inch rack width. A 42U rack holds 21 units: 10.5 PH/s aggregate hashrate at approximately 156 kW total power. The 2U height and 20.5 kg weight allow single technician installation. Quick disconnect water fittings for tool free coolant connection and miner swapping. Designed for professional data center deployment, not home mining.

Closed loop water or water glycol system. Pump to circulate coolant. Heat exchanger (CDU, dry cooler, or radiator) to dissipate heat. Supply and return plumbing with quick disconnect fittings per unit. Rack manifold for multi unit deployment. Flow rate approximately 8 to 10 L/min per unit. Inlet coolant temperature 20 to 40 degrees Celsius. No dielectric fluid required. Single unit cooling infrastructure costs approximately $1,000 to $3,000. Full rack system $7,000 to $20,000.

50 dB. Water cooling eliminates high speed fans. Comparable to a quiet conversation. 25 dB below air cooled Bitcoin miners at 75 dB. Suitable for shared data center environments with noise restrictions. At 21 units per rack, the aggregate noise from a full rack remains manageable in professional facility settings.

SEAL01 is Bitdeer's first generation proprietary SHA-256 mining chip. Bitdeer designs chips in house through their SEAL program. The SEAL01 powers the entire A2 series: A2 Hyd (446 TH/s, 16.5 J/TH) and A2 Pro Hydro (500 TH/s, 14.9 J/TH, this product). The SEAL02 chip (A3 series) is the second generation delivering 12.5 J/TH. The SEAL04 chip (A4 series) is the third generation delivering sub-11 J/TH. Each generation represents a meaningful efficiency step.

MM lists 5 to 40 degrees Celsius. CryptoMinerBros and ZC Miner list -30 to 70 degrees Celsius. ASIC Marketplace lists -30 to 55 degrees Celsius. The wide range from other sources likely reflects storage temperature rather than optimal operating range, or includes the full coolant temperature envelope. The 5 to 40 degrees Celsius range for inlet coolant temperature is typical for hydro miners. Verify with Bitdeer documentation for operational specification versus storage specification.

All SHA-256 proof of work cryptocurrencies. Bitcoin (BTC) primary. Bitcoin Cash (BCH), Bitcoin SV (BSV), eCash (XEC), Fractal Bitcoin, and other SHA-256 chains. Same coin compatibility as the A3 series and all Bitmain SHA-256 hardware.

Yes per MM box contents. Built in PSU accepting 380 to 480V three phase. No external PSU to source. Water cooling infrastructure (pump, heat exchanger, plumbing) is NOT included and is the buyer's responsibility.

Connect 380 to 480V three phase power cable. Connect water supply and return lines via quick disconnect fittings to your cooling loop. Start coolant circulation and verify flow. Connect Ethernet cable. Find miner IP through Bitdeer IP scanner or network scanning. Open web interface, configure SHA-256 pool URL and BTC wallet address. Verify hashrate stabilizes at approximately 500 TH/s. Professional installation recommended for first time hydro deployments.

Yes. MillionMiner hosting facilities include hydro infrastructure and 380V+ three phase power. At $0.07 per kWh hosted: +$6.09 daily. Hosting eliminates the need to build water cooling infrastructure and source three phase power, which are the two primary barriers to hydro miner deployment. For buyers who want A2 Pro Hydro economics without building facility infrastructure, hosted deployment is the practical solution.

Yes, depending on deployment horizon and electricity rate. The A2 Pro Hydro at $6,900 produces +$4.30 daily. The A3 Pro Hydro at $10,449 produces +$3.56 daily. The A2 Pro Hydro generates more daily dollar profit right now because of lower CapEx. Over time, the A3 Pro Hydro's 16 percent efficiency advantage compounds: it consumes less electricity for more hashrate. The crossover (where total A3 profit exceeds total A2 profit) occurs at approximately month 26 at $0.08 per kWh. If you plan to mine for under two years, the A2 Pro Hydro is the better CapEx deployment. If you plan three+ years, the A3 Pro Hydro wins. Electricity rate shifts this calculation significantly.

360 day Bitdeer manufacturer warranty per BT-Miners. Covers manufacturing defects and hardware failures under normal operating conditions. Warranty may be voided by improper coolant use, operating outside specified temperature range, or voltage errors. Verify warranty terms through MillionMiner as the selling distributor.

Standard hydro ASIC maintenance. Quarterly coolant system inspection (levels, quality, flow rate). Check quick disconnect fittings for leaks. Monitor hashrate through Bitdeer web interface. Replace coolant filter if present. The 2U form factor allows individual unit removal without disturbing adjacent rack units. Hydro miners generally experience longer chip lifespans than air cooled due to more consistent thermal conditions.

A2 Pro Hydro: 21 x 500 TH/s = 10.5 PH/s per 42U rack at approximately 156 kW. Bitmain S21 XP Hydro (2U): 21 x 473 TH/s = 9.93 PH/s per rack at approximately 119 kW. Bitmain S23 Hyd (2U): 21 x 580 TH/s = 12.18 PH/s per rack at approximately 116 kW. The S23 Hyd delivers the highest per rack hashrate at the lowest per rack power. The A2 Pro Hydro delivers competitive per rack hashrate but at substantially higher per rack power consumption. Facility power capacity may limit how many A2 Pro Hydro racks can be deployed versus newer, more efficient alternatives.

The A2 Pro Hydro is the highest daily profit per CapEx dollar among currently in stock hydro Bitcoin miners at MillionMiner. At $6,900 with +$4.30 daily and approximately 54 day payback, the ROI timeline is aggressive. Buy if: you have or will build hydro infrastructure with 380V+ three phase, you prioritize maximum daily profit over maximum per terahash efficiency, your deployment horizon is under 26 months, or you want Bitdeer's vertical integration (chip design + mining operations). Consider the A3 Pro Hydro ($10,449) for deployments exceeding 26 months. Consider the Bitmain S21 XP Hydro ($6,899) if you prioritize per terahash efficiency at the same price point.
