The equipment is designed for the heat pickup of 47.5 MJ or 13.2 kW / h of electricity. For example, 4 Antminers S9 х 2,5kW (electricity power with overclocking) = 10 kW. At the same time, the installation itself consumes 0.165 kW for the operation of the circulation pump. It connects to a source of cold water up to 20 С degrees. It can be network circulating water, well water (river, ponder, lake), wellsite or closed circuit, that in its turn has a plenty of versions (pipes laid in the ground, returning network water to the main through the bypass, water draw-off heating etc.) With a normal electricity consumption of up to 10 kW / h, approximately 0.2 m³ of water per hour is required. As for electrcicity, the equipment is connected with a cable of 10 mm² x 5 copper wires. In the power panel, the cable is protected by a 20 amp device. In a regular installation panel, the cable is connected to a protection tripping unit of 20 amps. After that there is a contactor that turns on / off the power supply miners. There are 4 power devices one device for one miner. Also there are the devices for the control circuit, the pump and the block of two additional sockets for connecting a network switch, a computer, etc. As for water, the equipment is connected with a flexible connection. The heat exchanger pipes have an external thread of 3/4 inch, thus, depending on the cooling option you choose, reducing sockets may be required. To connect to the network plumbing flexible connection of 1/2 inch is suitable. In other cases, we will help you if necessary. It is preferable to set at the entrance a mash filter for water coarse filtering and a valve for smooth adjustment of the water supply to the heat exchanger. The volume of cold water supply will determine the temperature of the transfer liquid in the equipment. The recommended transfer liquid temperature is 50-65 degrees for the Antminer S9 (for other equipment, it may vary). It is equipped with overheating protection. The thermostat is set to 68-72 degrees. Thus, when reaching 72 degrees, the installation will be disabled. After cooling to 68 degrees it will turn on automatically. If needed the the threshold off/on can be changed, but we do not recommend setting it at more than 80 degrees. It is also envisaged the disabling of the equipment in case the transer liquid level in the its falls below the critical level.
