Dust control solutions leader Brasco Filtration has demonstrated its industry-leading capabilities by designing, manufacturing and installing a cutting-edge pressurisation fan filter system with integrated cooling for a prominent platinum mine in the North West province. This project showcases Brasco’s unparalleled expertise and innovation in dust control and air filtration solutions.

The project brief required Brasco to create a high-efficiency system that not only featured automated reverse pulse cleaning but also met specific temperature regulation parameters. Collaborating closely with Coolcare Refrigeration and Electrical Installations, which forms part of the Brasco Group, Brasco delivered a comprehensive solution that perfectly matched the client's needs.

The sophisticated system was engineered to support both a mine winder motor and a converter room housing high-caliber switchgear. Brasco provided a wall-mounted tube sheet with a robust holding frame designed to accommodate 32 pairs of high-efficiency cartridges. The filter system achieved an outstanding filtration efficiency of 99.997% at 0.3 microns, ensuring exceptionally clean air.

The system featured differential pulse controls with a 4-20 mA output, which effectively cleaned the cartridges while optimising compressed air usage. A 75 kW belt-driven fan set, mounted on anti-vibration mounts and equipped with inlet and outlet compensators, was installed to achieve an air volume of 28 m³/s, delivering clean, filtered air to the winder motor. Complementing this, an 18.5 kW direct-driven fan set was installed to service the converter room. Both fans worked in tandem, drawing air through the shared cartridge filter system.

To address the cooling requirements, a floor-mounted cooling coil system was installed. This system featured copper coils with aluminum fins encased in galvanized steel. Designed to cool the air from an inlet temperature of 45 °C to an outlet temperature of 35 °C, it effectively maintained optimal conditions around the winder motor.

The project also included the installation of galvanized ducting with mezz flanges to direct the clean, filtered air precisely where it was needed, ensuring efficient airflow to both the winder motor and the converter room.

Executed within budget and on schedule, this project is a testament to Brasco Filtration’s exceptional design and engineering capabilities. The successful completion of this project underscores Brasco’s commitment to delivering innovative, high-performance solutions that meet and exceed client expectations.
