Miner capacity depends on container size and miner model. A 20ft container can accommodate 154-176 units (such as approximately 154Antminer S19). A 40ft container can accommodate 336-396 units (such as approximately 396 Whatsminer M30S). A 45ft container can accommodate 420 units. A 53ft container can accommodate 478 units. Specific quantities also need to consider miner power and cooling requirements. High-power miners (such as S21 XP) require better ventilation space, and single container capacity will be reduced accordingly. Our technical team will provide optimal layout solutions based on your selected miner model, ensuring optimal balance between cooling effectiveness and hashrate density.

Maintenance costs are relatively low. Daily maintenance (cleaning fans, checking connections) is self-operated. Regular maintenance: fan filters ~50-100 USD/quarter, professional testing ~500-1000 USD/quarter. Annual maintenance ~3000-5000 USD (electrical inspection, anti-corrosion). Main wear parts: fans (300-800 USD, replace every 3-5 years), circuit breakers (200-1000 USD, 5-10 years). Optional annual service package ~5000-8000 USD/container covers all regular maintenance.

Absolutely! Our products are designed for global markets. CSC certified (globally recognized), with optional CE (EU) and UL (North America) certifications. Supports ocean, land, and rail shipping. Usually classified as "metal products" or "prefabricated buildings" with 0-15% tariffs in most countries. We customize voltage for destination countries (USA: 220V/480V, Europe: 230V/400V, etc.) and assist with customs documentation.

Yes! Our mining racks use modular design with adjustable heights and spacing for new miners (compatible if width ≤450mm). Electrical system reserves expansion space for capacity upgrades or cooling system adjustments. Management system supports software upgrades. Many customers have used containers for 3-5 years across 2-3 miner generations.

Delivery time depends on the selected solution and customization degree. Standard Shell Solution: 3-7 days for stock inventory, 15-20 days for custom production. Semi-Integrated Solution: 20-30 days (requires mining rack and wiring installation). Fully Integrated Solution: 30-45 days (including miner procurement and pre-installation commissioning). Customized Solution: 45-60 days (depending on customization complexity). If your selected miner model is relatively common (such as S19, M30 series), we usually have ready-made design solutions that can accelerate delivery speed. For urgent orders, expedited production can be applied for with an additional 10-15% expedited fee, reducing delivery time by approximately 30%.

Both cooling solutions have their advantages. Choose air-cooled solution if your mining farm is located in dry or semi-arid climate regions, electricity prices are low and energy costs are not sensitive, maintenance personnel have limited technical capabilities, budget is tight (air cooling costs 20-30% less), and you are using air-cooled miners (such as S19, S21, M50, etc.). Choose water-cooled solution if your mining farm is located in high-temperature humid regions (such as Southeast Asia, tropical areas), has strict noise requirements (such as near residential areas), wants to improve miner stability and lifespan, has sufficient power and wants to improve cooling efficiency, or uses water-cooled dedicated miners (such as S9 Hydro, M33S). If uncertain, we can provide free solution consultation services based on your specific location and climate conditions.

Different specifications have varying power requirements: 20ft containers have a maximum design power of 800kW with a recommended incoming supply of 1000A at 460V three-phase working voltage; 40ft containers have a maximum design power of 2000kW with a recommended incoming supply of 2500A; 45ft containers have a maximum design power of 2150kW with a recommended incoming supply of 3000A; 53ft containers have a maximum design power of 2400kW with a recommended incoming supply of 3500A. Actual power consumption will fluctuate based on mining machine models, operating status, and ambient temperature, so it is recommended to reserve a 10-15% margin. Our power distribution system adopts a modular design, allowing flexible adjustment of power configuration according to the actual number of mining machines. If the power supply is unstable, it is recommended to additionally configure UPS uninterruptible power supply, automatic transfer switches, and lightning protection devices.

Transportation conditions: Ocean shipping can use standard container cargo ships, freight calculated by volume. Land transportation requires flatbed trucks or container trucks, ensuring transport route clearance height not lower than 3.2 meters. On-site requires 15-ton or above crane or forklift for lifting. Installation conditions: Site requires level hardened ground (concrete or compacted gravel), slope ≤3%. Power supply requires power access point matching container power, recommended within 10 meters of container. Network requires stable internet access (wired or 4G/5G). Ventilation surroundings need sufficient air circulation space, at least 2 meters front and rear. We provide detailed "Site Preparation Guide" and can dispatch engineers for site survey and installation guidance. Standard installation takes only 2-3 days.

Our mining containers are designed to meet C3/C4/C5 environmental rating standards, suitable for various harsh environments. C3 is suitable for temperate climates with low pollution (such as rural areas, suburbs). C4 is suitable for marine climates or industrial pollution environments (such as coastal areas, industrial parks). C5 is suitable for highly corrosive environments (such as near-shore areas, high-humidity chemical zones). Container bodies undergo hot-dip galvanizing or professional anti-corrosion coating treatment, capable of normal operation in ambient temperatures from -40°C to +55°C. Air-cooled systems are suitable for dry climates, water-cooled systems are suitable for high-temperature humid environments.

We have integrated multiple safety protection systems. Electrical safety: industrial-grade circuit breakers, leakage protection, flame-retardant cables, IP54-rated electrical cabinets. Fire safety: A-grade fireproof rock wool insulation, smoke detectors, optional automatic fire suppression. Structural safety: withstands category 12 typhoons, 8-degree seismic design, anti-theft doors and windows. Environmental monitoring: real-time temperature and humidity monitoring, automatic alarms, remote monitoring.
