Brazilian mine benefits from cooling system installation
Mine ventilation, refrigeration and cooling engineering consultant BBE Group has successfully completed the installation of a ventilation and cooling system at the Caraíba mine, in the Curaçá river valley, in Brazil.
“BBE was brought in to consult on and supply the full cooling system, which includes a radiator, spot cooler, fan and cooling coil, as well as general ancillary items,” says BBE director Richard Gundersen.
The system has maintained an air temperature under 30 °C since it was commissioned in November 2021.
Gundersen says that KTI had developed its range of specialised underground chillers with cooling capacities of up to 600 kW in one unit, but until this contract, had yet to find a suitable client.
“An engineer from United Mining Services, served as our ‘eyes on the ground’, helping us assess the mine’s requirements so that we could work on the best possible solution for the mine, without having to travel to Brazil to do so,” he says.
He suggests that, not only were logistics a challenge for the project, owing to the various component suppliers being on different continents, but so was the language cocktail and time differences between the German, Brazilian and South African technicians working on the project.
A fully qualified technician from KTI was able to commission the complete installation.
