Bitdeer SEALMINER A2 Hydro official specifications and infrastructure boundary

SEALMINER A2 Hydro official performance contract

• Comparison nominal/bin: 446 TH/s at 7359 W
• Manufacturer efficiency: 16.5 J/TH
• Published hashrate range: 446–446 TH/s
• Published power range: 7359–7359 W

Exact launch nominal; Normal and High Hash coolant modes have different inlet-temperature limits.

SHA-256 and the manufacturer-listed BTC, BCH and BSV workload labels are retained. They are not profitability or current network guarantees.

Hydro-cooling and facility boundary

The A2 Hydro guide specifies Normal mode coolant inlet 20–55 °C and High Hash inlet 20–45 °C, flow at least 10.2 L/min and inlet pressure no more than 350 kPa. Use distilled water with corrosion inhibitor and antifreeze as conditions require; copper piping is prohibited. Cooling must circulate, purge and pass leak/condensation checks before energizing. Drain promptly when disconnected, stored or exposed to freezing risk.

Hydro units ship without power cables by default. Replacement-PSU dimensions and mass are not whole-miner dimensions.

Acoustic, physical and firmware boundary

Manufacturer language such as low-noise or near-silent is qualitative. No absolute dBA test protocol is published, so the former 50/75 dB values are withheld. Whole-miner dimensions, weights and environment fields are withheld where accessible first-party text did not authenticate them.

Firmware is exact-model and revision gated. Do not cross-flash Air/Hydro, base/Pro or A2/A3 artifacts. A2 Air Single Input and Double Input packages are distinct. A future CTA requires exact selector, controller/board match, version, checksum and rollback instructions.

Current revenue, profit, MSRP, BTU and home-suitability claims are unavailable.

Exact physical, electrical and environmental table

• Miner dimensions: 482 x 665 x 88 mm; net weight: 20.5 kg
• Package: 567 x 787 x 203 mm; gross weight: 23 kg
• Input contract: {"voltage":"380-480 VAC","phase":"3-phase","max_psu_input_w":10000,"max_current_a":20,"frequency":"47-63 Hz","connector":null}
• Environment/cooling contract: {"coolant_inlet_c":"20-55","storage_c":"-30 to 70 after draining","rh":"10-90% noncondensing","liquid_pressure_bar_max":3.5,"pure_water_flow_l_min":10.199999999999999289457264239899814128875732421875,"glycol_30pct_flow_l_min":11}

Maximum PSU input and current are equipment-table limits, not branch-circuit designs. Connector, phase or protective-device fields remain unresolved wherever the manufacturer table is silent.
