Antrack V2 Specifications

Antrack V2 Cabinet Specifications

The cabinet side of the Antrack V2 houses the compatible mining servers, coolant manifold, power connections and primary circulation equipment. Its compact dimensions allow four hydro miners to be organized within a footprint considerably smaller than a containerized mining facility.

The 24kW maximum load applies to the combined mining-server demand. Operators should verify the individual power consumption of every installed server before loading the cabinet.

Physical compatibility should also be confirmed. The fact that a machine uses hydro cooling does not automatically mean that its dimensions, hose connections, power interfaces and firmware are suitable for the Antrack V2.

Antrack V2 Heat-Pump Specifications

The heat-pump side receives thermal energy carried away from the mining servers by the coolant circuit. It can then reject or recover that heat, depending on the final system design.

The listed 32kW heating capacity is higher than the rack’s 24kW maximum mining load because the heat-pump system can move thermal energy using additional electrical input. It should not be interpreted as a 32kW mining capacity.

The heat-pump module must be positioned where its fan airflow remains unobstructed. Maintenance access should be preserved around the fan, pump, piping and service connections.

Advanced Hydro Cooling Performance

The Antrack V2 transfers heat from compatible ANTMINER servers through a circulating liquid loop. Coolant passes through the miners, absorbs heat from internal components and carries that energy to the heat-pump side.

This approach removes the need for the high-speed server fans commonly used by air-cooled ASIC miners. As a result, a properly installed hydro system can reduce miner-level noise and provide more controlled chip temperatures.

Hydro cooling can also reduce direct exposure of miner components to dust and airborne debris. However, it introduces additional requirements involving pumps, coolant chemistry, seals, manifolds and leak detection.

The supplied specifications list an acceptable liquid pH range of 7.8–8.5. Operators should use only coolant and water-treatment methods approved for the system and installed mining equipment.

Coolant quality should be tested periodically. Incorrect pH, dissolved minerals, corrosion products or biological growth can restrict passages, damage components and reduce thermal performance.

BITMAIN publishes additional guidance for water quality in its hydro cooling infrastructure. Operators should review the official BITMAIN hydro cooling water-quality requirements as part of system planning.

80°C Hot-Water Heat Recovery

One of the most distinctive features of the Antrack V2 is its ability to provide hot water at a listed outlet temperature of up to 80°C. This can allow mining heat to become a usable energy resource rather than being discharged entirely into the environment.

Potential heat-reuse applications may include:

• Building space heating
• Domestic hot-water preheating
• Greenhouse heating
• Swimming-pool heating
• Agricultural drying
• Workshop or warehouse heating
• Suitable industrial processes

The actual amount of recoverable heat depends on mining load, inlet-water temperature, flow rate, outdoor conditions and heat-pump operation. The quoted outlet temperature does not guarantee that every application will continuously receive water at 80°C.

A heat exchanger may be required to separate the mining coolant circuit from building or process water. Pressure relief, expansion control, temperature regulation and scald protection should be incorporated where necessary.

Any connection between the Antrack V2 and a building-heating or potable-water system should be designed by qualified mechanical and plumbing professionals.

Antrack V2 Miner Compatibility

The Antrack V2 is designed to support four compatible ANTMINER hydro servers. The exact supported models may vary according to the rack interface, power demand, cooling connections and production version.

Before installing a miner, confirm:

• The exact ANTMINER model and production batch
• The machine’s maximum power consumption
• The physical dimensions and mounting format
• The coolant inlet and outlet connections
• The required flow rate and pressure
• The power-plug and cable configuration
• The miner firmware version
• The total combined cabinet load

The total mining load must remain within 24kW. Installing four machines rated above 6kW each could exceed that limit, even if they physically fit inside the rack.

Antrack V2 Electrical Requirements

The Antrack V2 requires a three-phase 380–415V electrical supply operating at 50–60Hz. The listed input-current requirement is 80A.

The supplied power conductor specification is 6AWG, approximately 16mm². Final conductor sizing must still account for cable length, installation method, ambient temperature, local electrical codes and continuous-load requirements.

The electrical installation should include:

• Correctly rated three-phase conductors
• Protective grounding
• Suitable overcurrent protection
• Phase balancing
• Surge protection
• Lockable isolation equipment
• Accessible emergency shutdown
• Protection from water and condensation

The 24kW server load does not include every auxiliary component. Water pumps, heat-pump equipment, monitoring systems and networking may add to total facility consumption.

Only qualified industrial electricians should connect and commission the Antrack V2. The system is not suitable for standard residential outlets.

Antrack V2 Installation Guide

Installing the Antrack V2 requires coordinated electrical, hydraulic, structural and network preparation. Both the cabinet and heat-pump unit need stable foundations and adequate maintenance clearances.

1. Prepare level foundations for the cabinet and heat-pump module.
2. Confirm that the installation surfaces can support 140kg and 375kg respectively.
3. Provide suitable delivery and lifting access.
4. Install the required 380–415V three-phase electrical supply.
5. Complete grounding, protection and emergency-disconnect systems.
6. Position the heat pump where fan airflow will remain unrestricted.
7. Install correctly sized coolant pipes between the two units.
8. Flush and pressure-test the cooling circuit.
9. Fill the system with approved coolant at the correct pH.
10. Connect Ethernet networking and monitoring equipment.
11. Install compatible hydro miners in the designated slots.
12. Confirm that the combined server load does not exceed 24kW.
13. Start the pumps and remove trapped air from the circuit.
14. Check every connection for leaks.
15. Commission one miner at a time while monitoring temperature and flow.

Do not energize mining servers until adequate coolant circulation has been confirmed. Running hydro miners without proper flow can cause rapid overheating and equipment damage.

Maintenance and Coolant Management

Routine maintenance helps protect the Antrack V2, the installed miners and the heat-recovery system. Operators should maintain written inspection and coolant-service schedules.

• Inspect pumps for vibration, noise and reduced flow.
• Check hoses, manifolds and fittings for leaks.
• Test coolant pH and condition regularly.
• Remove trapped air from the liquid circuit.
• Inspect electrical terminals for heat damage.
• Keep the heat-pump fan and heat-exchange surfaces clean.
• Monitor inlet and outlet temperatures.
• Verify that pressure remains within the approved range.
• Maintain clear service access around both units.
• Record temperature, load and pump-performance trends.

A gradual increase in miner temperature may indicate restricted flow, degraded coolant, pump wear, trapped air or fouling inside the cooling circuit.

Why Choose the Antrack V2?

The Antrack V2 may suit professional miners who need hydro cooling capacity without deploying a full-size container. Its four-miner configuration offers a more compact entry point for testing or expanding hydro-cooled operations.

The principal advantages include:

• Capacity for four compatible hydro miners
• Maximum 24kW server load
• Reduced dependence on miner-level cooling fans
• More controlled operating temperatures
• Compact rack footprint
• Integrated coolant circulation
• Potential recovery of mining heat
• Hot-water output up to 80°C
• 365-day listed warranty

The system can be particularly valuable where useful demand exists for recovered heat. However, the financial benefit depends on electricity cost, mining performance, climate, heat demand and the expense of integrating the hot-water system.
