    20ft Sea ContainerStandardized, internationally accepted standard housing, certified and proven design, seaworthy.
    Puristic DesignDue to its standardized dimensions, our units are designed to be transported by virtually any vehicle (road truck, vessel, train) capable of transporting 20 or 40 ft containers (TEU/FEU).
    StackabilityBased on stackable standard containers, our units can be stacked on top of each other to form a powerful, functional array: A stack of 2x3x3 units can be deployed in less than an hour, requires a mere 100 Sq m of floor space and provides an energy conversion of about 1 Megawatt. A stack can share infrastructure features such as satellite / 4G uplinks.
    Built to LastBuilt from best established Corten steel, harsh climate conditions and corrosion are not a problem anymore as this type of steel was originally developed for use without paint. Also known as “weathering steel”, this material rapidly develops a patina of iron oxide, which protects the steel from further corrosion.
    Readily rearrangeableUsing a standard forklift truck, our units can be rearranged any time. For example, if used as an auxiliary heater in a warehouse or greenhouse, the units can be moved in- and outside as required by the season. For heating warehouses or industrial halls, the units can be moved from one place to another depending on the required local air temperatures. Additionally, the units can be moved between transformer stations inside industrial buildings to ensure the best use of spare capacities and avoid the need for large, long, inefficient cables.
    Remote ManagementAutomatic satellite antenna positioning allows for convenient and automated adjustments. The satellite antenna is positioned on the basis of receiver signal strength indications, ensuring a functionally optimized and autonomous positioning anywhere in the world. For transportation purposes, or in case of severe weather conditions (storms), the antenna can be automatically retracted, laid flat on top of the container or fully removed manually. All of these features are remotely manageable.
    SystemRacks inside the container contain the computer systems which are either graphical processing unit based (GPU-based) or based on the high-performance cubic/cylindrical shape of the “antminer”.

    In the GPU-based computers, the GPUs are the energy-intensive parts with a “hot(H)” and a “cold(C)” side and are thus placed as far as possible from each other. In general, the GPUs are arranged along the long horizontal axis of a shelf (width of the shelf). The order of the GPUs is important. They are in an ...HC-CH-HC-CH-HC... alternating order (each GPU rotated by 180 degrees compared to its neighbor), forming CH-HC-pairs, and the distance between two opposing hot sides is much further compared to the distance between two opposing cold sides. Additionally, each HC-CH pair of GPUs is placed alternatingly away from the neighboring pairs of GPUs on the second horizontal axis perpendicular to the axis of the primary direction of the GPU arrangement on the rack of shelves (long axis of the shelf). These results are based on a working prototype, where optimization experiments and calculations using thermography and air-flow simulations have resulted in the development of this schema.

    Heat Simulation

    Adjustable RacksThe positions between the racks are readily adjustable by using an archive rack system on rails. Rails are welded into the container when they are manufactured. To ease maintenance and for cooling optimization, the racks can later be moved along the short horizontal axis of the container so that the space between racks can be adjusted.

    Cooling System

    Fail-Proof Air FlowCentrally installed fans (one each side) with a large fan diameter are highly efficient and superior to small fans installed inside the equipment. These fans create a pressure gradient with a lower pressure inside the container by pushing the air out of the container. The inflow is exclusively possible via (adjustable) air inlet hoses that lead the inflowing air directly to the equipment that needs cooling. This way, the same airflow that could be achieved using standard small diameter fans can be created by investing fractions of the energy required by small fans. Moreover, a fail-proof system is generated, since cooling of the individual components can be considered “passive”. Failure of one of the (at least) two large diameter fans results in compensatory upregulation of the remaining fan, an automated maintenance message and full cooling capacity for the remaining time to maintenance even with only a single fan running.
    The racks are placed in a special order that allows the incoming air to reach all GPUs

    For “tube-like” cylindrical computing units like the “antiminer S9”, a hose is directly fitted onto the air inlets of the antminer. The fans can be completely removed, since an adequate air flow is always ensured passively.

    Filters that can be placed inside the air intake hoses (depending where the container is deployed, filters may not be necessary at all) can be automatically purged by a maintenance sequence in the fan controller to reverse the fans – and thus the pressure gradient – forcing airflow in the opposite direction. This is achieved by temporarily changing two phases of the 3-phase AC fan motors by using two relais during the fans' off cycle. Reversing the pressure results in a purge of dirty filters/nets in the air inlets.

    The condition of the nets is calculated by determining the pressure difference induced by activating the fans. By means of a calibration curve, the relative decrease in pressure after the fans are activated is used to estimate the resistance of the whole system which correlates with the degree of obstruction of the air inlets. Simulatneous power measurements of the fan power lines allows for reliable identification of properly running fans.
    Sensors Humidity and water sensors identify various weather conditions. If a container is deployed outside, severe storms and rain will be detected and the ventilation system adjusted so that no water can be sucked into the container. The pressure and temperature sensors mentioned above will control ambient outside and inside air temperatures, allowing for adjustments of the converted energy and cooling power to the required (preset) temperatures. In certain use-cases, it may be desirable to increase the operating temperature of the unit (e.g. heating a swimming pool). The sensors allow for such adjustments to be set and monitored remotely.
    The fan control is realized by means of a PID loop with setpoint: Temperature, Input: Temperature Readings, Current Readings, Output: Hashrate-factor, Fan Driver Circuit

    Electrical System Features

    Power supplyElectrical power supply is realized via regular, internationally accepted CEE 32-Amp hubs. Depending on the type, either 2 or 4 plugs are installed.
    Power ManagementThe distribution of power is controlled through a small linux-based server system and Atmel® chip-based microcontrollers. Using node.js-based applications and accessed via http-served dashboards, the general purpose in-out pins of a server-connected control board or of a raspberry single-pcb-computer are used to trigger a set of solid state relays that control the power connections of the power supply units of the computing and mining rigs.
    Surge protectionAn essential feature of a safe and feasible startup procedure is a strategy to cope with the massive surge currents imposed by the large capacitive loads of the power supply units. Operation without physical access to the unit’s power switches and fuses, by simply connecting the power plugs, is therefore only possible by using a strategy to reduce these massive surge currents. Our strategy involves the use of random solid state relays activated within 20 seconds. Once power is supplied, all solid-state relays are in an “off” state. After about 10 seconds, the linux-based server system and Atmel® chip-based microcontrollers are up and ready. A startup script is then automatically executed, randomly activating the solid-state relays for the (16) racks, ensuring that only one rack receives power at a time. Once turned on, a second, rack-specific set of (3) solid-state relais controlled by an atmel microcontroller is sequentially activated. Power consumption is also read by this controller and sent to the corresponding server via the serial line (USB connection)..
    Automatic startup sequenceThe automatic startup sequence safely connects standard plugs to the system without the need for sophisticated, special circuit breakers, ensuring the versatility of the container to be plugged into virtually any sufficient power source.
    Automatic shutdown sequenceAnalogous to the automatic startup sequence, the capacitive loads are disconnected sequentially from the power plugs upon entering a (secret) code into the numpad that is used for access control purposes. This code triggers the closure of a signal circuit connected to the central servers, which will trigger a shutdown program once it senses the closure of the circuit, shutting down all solid-state relais so that plugs can be removed safely and avoiding electric arcs inside the plugs.
