Product Overview

The Bitdeer SealMiner A2 Pro Hydro 500TH is a next-generation SHA-256 ASIC miner designed for serious Bitcoin and Bitcoin-fork mining operations. It delivers a hashrate of 500 TH/s (typical, up to ~530 TH/s) with a power draw starting around 7,450W, achieving an energy efficiency of 14.9 J/TH in a compact, rack-mountable hydro-cooled form factor.

Optimised for BTC / BCH / BSV, the A2 Pro Hydro combines high-density performance with advanced liquid cooling, making it ideal for high-capacity mining rooms, containers and data centres where airflow, heat and noise must be tightly controlled.

Key Features

• 500 TH/s SHA-256 performance
  Industrial-grade hashrate for Bitcoin and other SHA-256 coins, with an official range of 500–530 TH/s depending on operating mode and conditions.

• High efficiency at 14.9 J/TH
  Designed to run around 7,450–7,900W, the A2 Pro Hydro targets a power efficiency of 14.9 J/TH (±5%), placing it in the high-efficiency tier of current-generation Bitcoin miners.

• Advanced hydro-cooling system
  Instead of traditional air cooling, the miner uses a closed-loop watercooling system to move heat away from the hashboards. This supports higher density deployments, more stable chip temperatures and significantly lower acoustic output compared to large air-cooled units.

• Low-noise operation
  With the cooling load shifted into a hydro loop and external radiators, the A2 Pro Hydro is rated at roughly 50 dB at the unit itself in suitable setups, substantially quieter than typical 75–80 dB air-cooled ASIC miners.

• Rack-mount 2U server style
  The chassis follows a 2U server design that is suitable for racks and professional environments, making it easier to integrate into existing infrastructure and mining containers.

Power, Hydro Loop & Installation Notes

The SealMiner A2 Pro Hydro is a high-power, high-density miner and should be deployed in an environment that is properly engineered for both electrical load and liquid cooling:

• Electrical requirements (South Africa context):

  • Ensure a dedicated 230V circuit per unit with correctly sized breakers and wiring.

  • Use industrial-grade cabling and plugs rated comfortably above the continuous ~7.5–8 kW draw.

  • Total electrical design should be verified by a qualified electrician familiar with high-load equipment.

• Hydro-cooling loop:

  • Requires a compatible pump, radiator(s) and plumbing sized for the miner’s heat output and recommended flow rate.

  • Maintain coolant quality (distilled water + additive) and regularly inspect for leaks, flow issues and air pockets.

  • Place radiators and fans where hot air can be exhausted effectively from the room or container.

• Site planning:

  • Best suited to dedicated mining rooms, containers or data centres, not residential living areas.

  • Allow sufficient clearance around the unit for hose routing, power cabling, and access for maintenance.

Correctly specifying the electrical and hydro-cooling system is critical for safe, reliable 24/7 operation and to keep chips within the intended thermal envelope.

Ideal Use Cases

• Professional Bitcoin mining farms looking to add high-density, liquid-cooled SHA-256 capacity.

• Containerised / mobile mining solutions where air-cooling noise and exhaust heat are a constraint.

• Operators transitioning from older, less efficient air-cooled fleets to new-generation 14.9 J/TH hardware.

The A2 Pro Hydro is particularly attractive in setups where you can leverage existing chilled-water or heat-recovery infrastructure, or where air-cooled noise and hot exhaust are a challenge.

What’s Included

• 1 × Bitdeer SealMiner A2 Pro Hydro 500TH unit

• Integrated power supply (AC input)

Important:

• Hydro-cooling components (pump, radiator, reservoir, coolant, hoses, fittings) are typically not included and must be sourced and installed separately.

• Power cables may not be included by some suppliers; ensure you have appropriately rated cables and connectors for your local standard.
