In a Brazilian gold mine, we installed an underground ventilation system, our Underground Chiller UC 500, with a cooling capacity of up to 600 kWR. The mine urgently needed spot cooling to deepen the shaft for further exploration. Since our underground chillers are specifically designed for the adverse conditions and can be easily moved through the mine, installation and commissioning was quick. The mine now meets its safety requirements for safe working.<\/strong>\u00a0In 2021, we were approached by our customer when an urgent need for underground cooling arose in the course of shaft deepening. In cooperation with a partner company that is a global leader in mine ventilation, we were able to develop a cooling concept on site. Our Underground Chiller was integrated into the cooling concept as it offers several advantages compared to conventional water coolers. A crucial requirement was the high corrosion potential due to the acids and minerals contained in the groundwater. Due to the special design and material selection of the heat exchangers, the Underground Chiller was able to cope with this without any problems. In addition, the service life is much longer as a result. The entire unit was lowered upright through the shaft and then simply moved underground to where it was needed. This met a second requirement and avoided the need to build special ramps. After placing and connecting the chiller to water, power and cooling car, our trained technicians successfully commissioned the chiller. Several tests were carried out and the performance record of the Underground Chiller was established to the full satisfaction of all parties involved<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
