Overview
The Bitdeer SealMiner A3 Pro Hydro 660T is an industrial SHA-256 miner built around a rated hashrate of 660 TH/s and power consumption of 8250W. At 12.5 J/TH, it targets operators who need high compute density while using centralized hydro cooling instead of conventional high-airflow thermal management.
The chassis uses a compact 2U format measuring 665 × 482 × 86 mm and connects to the mining network through Ethernet. It requires a 380–480V electrical supply, so buyers should verify site voltage, circuit capacity, protection equipment and connector requirements before ordering. The cooling loop, heat rejection equipment and installation fittings must also be sized for the full 8250W thermal load.
This model mines Bitcoin and other compatible SHA-256 networks. Actual hashrate and efficiency can vary with operating conditions and delivered-unit tolerances. Pool results, electricity cost and network conditions determine operational economics; no fixed mining return is implied.
Before deployment, confirm the current batch’s coolant specifications, flow requirements, inlet conditions and electrical configuration with Bitark. The miner should be installed by qualified personnel in infrastructure designed for continuous high-load operation.

Bitdeer SealMiner A3 Pro Hydro 660T FAQs
It is rated at 660 TH/s with 8250W power consumption and 12.5 J/TH efficiency. Delivered performance may vary within the applicable production tolerances and operating conditions.
The miner runs the SHA-256 algorithm. It is primarily configured for Bitcoin and can also work with compatible SHA-256 networks such as Bitcoin Cash and Bitcoin SV when supported by the selected mining pool.
The specified input range is 380–480V. Have a qualified electrician confirm voltage, circuit capacity, phase configuration, protection devices and cabling for continuous 8250W operation before installation.
No complete facility cooling system should be assumed. This hydro-cooled miner requires a compatible external coolant loop and heat-rejection system. Contact us to confirm the current batch's connections, coolant, flow and inlet requirements before ordering.
It is intended for purpose-built mining infrastructure. Its 8250W load, 380–480V input and external hydro-cooling requirements generally make it unsuitable for ordinary residential or office electrical systems.
The stated manufacturer warranty is 365 days from shipment and remains subject to the applicable warranty terms. Incorrect installation, unauthorized modification or operation outside approved conditions may affect coverage.
