Detailed description and instructions The unit is designed for heat removal of 95 MJ or 26.4 kW/h of electricity. For example, 8 Antminer S9 x 2.5 kW (max. el. power, overclocked) = 20 kW/h. The unit itself consumes 0.165 kW on the circulation pump. It is connected to a source of cold water below 20 degrees Celsius. Tap water can be used, as well as, water from a reservoir (river, pond, lake), a well or a closed circuit, which presents lots of options (pipes laid in the ground, return of tap water to the water main through a bypass, heating of water intake, etc.). During routine operation below 20 kW/h, approximately 0.5 m³ of water per hour is required. Elecricity wise, the unit connects with a 10 mm² x 5 copper core cable. In the distribution board, the cable is protected by a 40 amps automatic circuit-breaker. In the unit's board the cable is connected to a 40 amps RCD, and then to a contactor that switches power for miner's circuit-breakers. 8 circuit breakers in total, 1 per miner. The board also features control chain circuit breakers, a pump, and a unit with four additional sockets for connecting a network commutator, a computer, etc. Water wise, the unit connects with a flexible flow pipe. The heat exchanger nozzles have a 3/4" external rifling, so, depending on the cooling option you choose, adapter couplings may be required. A 1/2" flexible flow pipe is enough to connect to a main water supply. In other cases we will consult you if needed. It is advisable to put a mesh filter for primary water refining and a valve for smooth adjustment of water flow to the heat exchanger. Volume of cold water supplied determines temperature of the coolant in the unit. Recommended coolant temperature is 50-60 degrees Celsius (for Antminer S9, may vary depending on hardware). The unit comes equipped with overheat protection. The thermostat is set to 68-72 degrees. When the unit heats up to 72 degrees it shuts down. After cooling down to 68 degrees it will turn on automatically. The user is able to change values of those thresholds, however it is ill-advised to set them above 80 degrees. The unit also features a system that automaticaly turns it off when level of coolant in the tank is lower then critical.
