Air-Cooled Mining Container

Our mining containers are designed to meet C3/C4/C5 environmental corrosivity classes for use in a wide range of demanding conditions. C3 suits temperate, low-pollution environments (such as rural and suburban areas), C4 suits marine or industrially polluted environments (such as coastal areas and industrial parks), and C5 suits highly corrosive environments (such as offshore or high-humidity chemical zones). The enclosure is hot-dip galvanized or treated with a professional anti-corrosion coating and operates normally across an ambient temperature range of -40°C to +55°C. Air-cooled systems suit dry climates, while liquid-cooled systems suit hot, humid environments.

Miner capacity depends on container size and miner model. A 20ft container holds 154–176 units (for example, about 154 Antminer S19 units), a 40ft container holds 336–396 units (for example, up to 396 Whatsminer M30S units), a 45ft container holds about 420 units, and a 53ft container holds about 478 units. Exact counts also depend on miner power and cooling requirements. High-power miners (such as the S21 XP) need more ventilation space, so per-container capacity drops accordingly. Our technical team provides an optimal layout based on your chosen miner model to ensure the best balance of cooling and hashrate density.

Each cooling approach has its strengths. Choose air cooling if your mining farm is in a dry or semi-arid climate, electricity is cheap and energy cost is not a concern, maintenance staff have limited technical skills, the budget is tight (air cooling costs 20–30% less), or you run air-cooled miners (such as S19, S21, or M50). Choose liquid cooling if your mining farm is in a hot, humid region (such as Southeast Asia or the tropics), noise must be strictly limited (such as near residential areas), you want to improve miner stability and lifespan, power is plentiful and you want higher cooling efficiency, or you run dedicated liquid-cooled miners (such as S9 Hydro or M33S). If you are unsure, we offer free consultation based on your specific location and climate conditions.

Lead time depends on the chosen package and degree of customization. Standard Enclosure Package: 3–7 days from stock, or 15–20 days for custom production. Semi-Integrated Package: 20–30 days (for installing miner racks and wiring). Fully integrated package: 30–45 days (including miner procurement and pre-installation/commissioning). Fully Customized Package: 45–60 days (depending on customization complexity). If your chosen miner model is common (such as the S19 or M30 series), we usually have a ready design that speeds delivery. Rush orders can be requested for an extra 10–15% expediting fee, shortening lead time by about 30%.

Shipping: sea freight can use standard container vessels with freight charged by volume; land transport needs a flatbed or container truck, with route clearance height of no less than 3.2 m; on-site lifting requires a 15-ton-plus crane or forklift. Installation: the site needs a level, hardened surface (concrete or compacted gravel) with a slope of ≤3%; power requires a connection point matched to the container's rated power, ideally within 10 m of the container; the network requires a stable internet connection (wired or 4G/5G); ventilation requires sufficient airflow space around the unit, at least 2 m front and back. We provide a detailed Site Preparation Guide and can dispatch engineers for a site survey and installation guidance. Standard installation takes just 2–3 days.

Power needs vary by size: a 20ft container has a maximum design power of 800 kW, with a recommended 1000A incomer at 460V three-phase; a 40ft container has a maximum design power of 2000 kW, with a recommended 2500A incomer; a 45ft container has a maximum design power of 2150 kW, with a recommended 3000A incomer; a 53ft container has a maximum design power of 2400 kW, with a recommended 3500A incomer. Actual consumption fluctuates with miner model, operating state, and ambient temperature, so we recommend reserving a 10–15% margin. Our power-distribution system is modular and can flexibly adjust the power configuration to the actual number of miners. If the power supply is unstable, we recommend adding a UPS, an automatic transfer switch, and surge protection devices.

We integrate multiple safety protections into the design. Electrical safety: industrial-grade breakers with automatic overload trip, residual-current devices that cut power immediately on detecting leakage, a grounding system for personal safety, flame-retardant cables that meet fire codes, and electrical cabinets with IP54 dust and water protection. Fire safety: Class-A fire-rated rock-wool insulation, smoke detectors for early fire warning, an automatic fire-suppression system (optional), and insulating mats to prevent static-induced fires. Structural safety: wind-resistant design rated for force-12 typhoons, seismic design meeting intensity-8 seismic standards, three-point-locking anti-theft doors and windows, and an emergency escape route. Environmental monitoring: real-time temperature and humidity monitoring, smoke and gas concentration monitoring, automatic alarms for abnormal conditions, and remote monitoring to check the container's status at any time.

Yes! Our design fully accounts for future expandability. The miner rack system is modular, with adjustable tier height and spacing to fit miners of different sizes. As long as the new miner's width does not exceed the standard rack (typically 450 mm), it is compatible. The power-distribution system has reserved expansion room: if the new miners draw more power, you can keep total power constant by reducing the number of miners per container, upgrade distribution-panel capacity (replacing breakers and busbars), or increase cooling capacity (adding fans or upgrading the liquid-cooled system). The smart management system supports software updates and is compatible with the monitoring protocols of new miner models. Many customers' mining containers have run continuously for 3–5 years, swapping through 2–3 generations of miners, with the enclosure still in normal service.

Maintenance costs are relatively low. Routine maintenance (monthly): clearing dust from cooling fans, checking electrical connections, and cleaning the floor and vents — all free, owner-performed tasks. Periodic maintenance (quarterly): replacing fan filters at roughly 50–100 RMB each, checking fasteners (free, owner-performed), and testing protection devices (a professional is recommended, roughly 500–1000 RMB per visit). Annual maintenance: a full electrical-system inspection at roughly 2000–3000 RMB, anti-corrosion touch-up painting at roughly 1000–2000 RMB, and replacement of aged parts at actual cost. Wear-part replacement costs: fans at roughly 300–800 RMB each (3–5 year life), breakers at roughly 200–1000 RMB each (5–10 year life), and lighting fixtures at roughly 50–150 RMB per set (3–5 year life). Our annual maintenance service package (roughly 5000–8000 RMB per container per year) covers all of the above periodic maintenance and routine wear-part replacement.

Absolutely! Our products are designed for the global market. International certifications include CSC certification (Container Safety Convention, recognized worldwide), CE certification (meeting EU standards, optional), and UL certification (meeting North American standards, optional). For export shipping, options include sea freight (most economical, suited to large-volume export), land transport (suited to neighboring countries in Central and Southeast Asia), and rail (China-Europe freight, faster than sea). For tariffs and customs clearance, units are typically classified as "metal products" or "prefabricated buildings," with most countries applying 0–15% tariffs, and we can help provide the documents needed for customs declaration. For localization, since voltage standards differ by country, we can customize to the destination country (United States 220V/480V, Europe 230V/400V, Japan 200V/200V, etc.).
