Between 2013 and 2017, we installed several slab ice plants and chilled water plants for our customer’s operations, providing a total of 1680 tons of slab ice per day. This corresponds to around 3 MW of chilled water at 3 °C. We prefabricated the plants in Germany and were thus able to reduce installation and commissioning costs enormously. A heat load of 15MW at a depth of 2,500m requires 25,000 tons of water at 5°C, but only 3,200 tons of ice. This leads to enormous savings in pumping energy, since the heated water would have to return to the surface. In 2013, our customer, a South African gold mine, approached us to expand its cooling systems. In total, this would require about 2000 tons of ice in the next few years. The ice would be produced on the surface of the mine. However, such a large cooling system requires an enormous investment. Together with other advantages associated with containerized, modular systems, we were able to help the customer take an approach that spreads the investment over several years. For example, in 2013 we delivered two plate ice plants, Ice Crusher and Ice Discharge System to the customer with a total production of 440 tons of ice per day. A short delivery time of our equipment quickly covered the need for cooling compared to only one large plant. In a second and third phase, the plant grew with the customer’s cooling needs, as did the mine. We delivered more modules until the plant reached full size in 2017, with a total production capacity of 1680 tons of ice per day. Two water pre-coolers were also installed to supply water at a temperature of 5°C to the ice plants. This is economical and energy efficient.
