1. Questions related to the cooling tower

A: The hot oil enters the coil heat exchanger located in the middle area of the cooling tower. Cooling tower uses the evaporation of water and fan to remove process heat, and the cooled oil flows out of the cooling tower and returns to the oil tank.

A:Approximately 25KW (maximum) for the fan, water pump and oil pumps.

A:The maximum cooling capacity of 720KW is currently tested with reference of a wet-bulb temperature at 28°C, as the wet-bulb temperature in the vast majority of the world is below 28°C. When the temperature is lower, the cooling tower can achieve a maximum cooling capacity of 720KW at a lower evaporation rate. When the temperature is above 28°C, the cooling effect of the tower will be slightly reduced. 720KW cooling capacity is approximately 1.7 times higher than the actual power consumption performance of the miner operation (calculated at 3.5KW per unit). A large margin is catered to meet the future higher power consumption requirements.
A:The testing result shows that it can accommodate approximately 1.2 tons of water, with a volume of about 1.2 cubic meters (2*2*0.3)

2. Questions related to the oil tank

A:The oil selected is Shell Immersion Cooling Fluid S3X with a flash point of 198° and a pour point of -42°, which can perform normally under most weather conditions. The oil pipe also has insulation, allowing a better flow of the oil.

It is recommended to cover the container while it is not in use, to protect it from extreme weather conditions.

A:A 40ft container uses approximately 6800L of oil, and each oil tank uses roughly 850L of oil. It varies slightly from miner to miner and can be given a specific value depending on the miner model. Based on the current market price of Shell S3x (brand) at US$9/liter, the cost of filling the oil tank is about ( 9*6800) US$61,200. The average hosting cost for each miner is around US$437.50 by adding the cost of coolant.

A:The PLC is simple to operate and we can ship out Minerbase with a common basic configuration. In consideration of the varying environment around the world, we have prepared operating manuals for each product. The detailed operating procedures provide users with setting information on various geographic locations for the mining site. Remote video support is also available for any additional questions.

A:The specification of the electrical enclosure only represents the maximum power consumption supported. If the overclocking power consumption is about 6KW per miner, then the total power consumption of a 40ft mining box is about 1.49MW.

3. Questions related to daily maintenance

A:In comparison to the air cooling model, the liquid cooling container requires daily maintenance for the cooling tower, including water replenishment, blockage removals of the air outlet (located at the top of cooling tower), and regular build-up removals inside the cooling tower (pay special attention to the water collection tray, air inlet window and the water spray device). Neither the water pump nor the oil pump can operate without liquid. Other maintenance includes the regular cleaning of the dust net, daily inspection of the oil tank level, oil seepage from pipeline valves and loose screws checks.

Please carefully prevent direct skin contact with the liquid as the cooling fluid is a volatile, toxic and irritating solution.

4. Questions related to selection of data center solution

A:The common consideration will be based on your requirements of the location, weather conditions, budget, mining farm setup/layout and daily maintenance. Our team will be able to provide more detailed consultation based on your specific requirements.

A:The A series and L series are suitable for outdoor server deployment. The A series has a larger capacity that supports up to 336 units of Antminer S19. The A series is a cost-effective option with an average hosting cost as low as $78 per miner*. The L series has the immersion liquid cooling system that is more advanced in terms of cooling technology with intelligent operation system and overclocking.

The T series is designed for indoor deployment. Its integrated oil tank that introduces the water heat recycling feature. By deploying the T series, miners will be able to recover heat generated from Bitcoin mining for greenhouse agriculture, fish farming, underfloor heating and many other great use cases.

*Without the consideration for logistics and other cost factors, the average miner price starts as low as about $110 for AN20 and $78 for AE40.

A:The most suitable cooling system depends on the scale and location of the operation. Air-cooling is common for small to medium-scale operations, while larger facilities may use liquid or immersion cooling for more efficient heat dissipation.

A:Efficiency: Liquid cooling is generally more efficient at heat dissipation.

Cost: Air-cooling is less expensive and simpler to maintain.

Scalability: Liquid cooling is more scalable and effective for larger operations.

A:To know which mining container is right for your operation, consider factors like power requirements, cooling solutions, security features, and portability. The choice depends on the scale of your operation and environmental conditions.

5. Questions related to the product features

A:Portability: Allows relocation to areas with cheaper electricity or more favorable climates.

Scalability: Easy to scale operations by adding more containers.

Reduced Infrastructure Costs: Minimal need for building or construction, reducing setup costs.

A:Compatible with ASIC miner brands such as Antminer, Whatsminer, Avalon and other common mining brands*. Miners with air cooling can also adopt the liquid tank by removing the fans (a fan simulator is required).

*The amount of slots available may differ depending on the manufacturer and model of mining equipment.

A:Depending on the container size and the design of the mining rigs, a standard 20-foot container can typically hold 50-100 mining rigs.

6. Questions related to the product operations

A:The ideal temperature for Bitcoin mining containers should be aligned with working temperature of miner models to ensure optimal hardware performance and longevity.

A:Bitcoin mining container power consumption varies widely based on the number and type of rigs. A single 40FT mining container can require 1.5MW, meanwhile a 20FT mining container can require 0.775MW

7. Questions related to immersion cooling

A:In immersion cooling, the mining hardware is submerged in a non-conductive liquid. Heat from the hardware is transferred to the liquid, which is then cooled and recirculated.

A:Typically, a dielectric mineral oil or engineered fluids specifically designed for heat transfer in electronics are used.

A:Immersion cooling is highly efficient and can significantly extend hardware life. However, it's more complex and expensive, making it suitable for large-scale operations where cooling efficiency and hardware longevity are critical.
