Q: What sizes and models of immersion cooling containers are available?

A: Our immersion cooling containers are specifically designed to accommodate standard shipping container sizes. We provide multiple options, including 10-foot, 20-foot, and 40-foot containers, all customizable to suit your mining machine capacity and operational needs.

The BC series offers various models, including BC40, BC20, BC10, and BC10Semi, while the MC series features MC40, MC20, and MC10. Additionally, the BC series provides Basic and Pro configurations to support a wide range of mining machine models.

Q: What is the difference between the Basic and Pro versions?

A: Our BC series offers both Basic and Pro configurations. The Pro version provides enhanced electrical setup and improved cooling capacity, allowing your mining machines to operate at higher power consumption levels for overclocking.

Q: What is the power consumption of your systems?

A: Our systems consume different amounts of power to run key components such as cooling fans, water pumps, oil pumps, and more. For instance, the BC40 Basic system has a self-power consumption of around 96 kW, excluding the miners.

Q: What is the difference between maximum power load and cooling capacity?

A: The maximum power load of a system is determined by the specifications of the distribution cabinet, indicating the highest power consumption the system can support. Similarly, the cooling capacity depends on the specifications of the cooling unit, representing the maximum cooling capability the system can handle.

For example, the BC40 Basic system is equipped with two 1200A x 2 distribution cabinets, supporting a maximum power consumption of 1.58 MW. Its electrical design includes redundancy to ensure a safety margin. In terms of cooling, the system is designed to handle a power consumption of 3.5 kW per miner and offers 1.34 MW of cooling capacity under standard operating conditions.

Q: Approximately how much oil is used per container?

A: The total oil consumption of our immersion cooling containers is based on the number of immersion cooling tanks used.

Typically, each cooling tank requires about 750-800 liters of oil, although consumption may vary depending on the specific miners being used. For example, the BC40 system, which includes 16 cooling tanks, needs approximately 13,000 liters of oil.

Q: Why are multiple coolers used in immersion cooling systems?
A: FogHashing’s immersion cooling system utilizes a modular, single-loop circulation design. Each pair of immersion cooling tanks, which consists of two inlets and two outlets, is linked to one cooler for effective heat dissipation.

For example, the BC40 system houses 16 immersion cooling tanks and is equipped with eight coolers. This design allows each tank to operate independently, offering the flexibility to open or close individual circulation loops. This modular setup ensures high system uptime and minimizes downtime during maintenance.

Q: What are the cooler options available?
A: The cooler choice can vary based on factors like environmental conditions, mining facility setup, and daily maintenance needs. The available options include both air coolers and closed-loop cooling towers.

Q: How does an air cooler work to cool the coolant?
A: An air cooler cools the dielectric liquid by exchanging heat with the surrounding air. The hot dielectric liquid travels through pipes to the air cooler, where fans blow air onto the cooler, facilitating heat exchange. This process reduces the temperature of the dielectric liquid.

Q: What type of environment is ideal for an air cooler?
A: Air coolers are best suited for dry, low-temperature, or humid environments where there are limited water resources. Their design relies on air to cool the dielectric liquid, making them effective in such conditions.

Q: How does a closed-loop cooling tower work?
A: A closed-loop cooling tower cools the dielectric liquid by using water and air to dissipate heat. The hot dielectric liquid is sent to the cooling tower through pipes, where it is sprayed over fillings and pipes. Fans introduce air into the tower to facilitate heat exchange between the water and the dielectric liquid, thus lowering the liquid’s temperature.

Q: What is the water consumption of a cooling tower?
A: Water consumption in a cooling tower depends on the system and environmental conditions. For instance, the BC40’s cooling tower circulates and reuses up to 50 tons of water per hour. Under extreme high-temperature or overclocking conditions, the water consumption remains minimal, not exceeding 1%. Thus, each cooling tower requires up to 0.5 tons of water per hour, with a maximum of four tons per hour for a 40-foot container equipped with eight cooling towers.

Q: What environment is best for a closed-loop cooling tower?
A: Closed-loop cooling towers, which utilize water for heat dissipation, are best suited for dry, high-temperature environments that also have access to sufficient water resources.
