Reliable Cooling for Mine Ventilation Expansion
Impala Platinum South Africa
To support increased production capacity, a South African platinum mining operation required an upgrade to its refrigeration and ventilation infrastructure. Contracted by BBE Projects, IWC (NEXT Cooling) delivered a high-performance cooling solution designed to operate reliably in harsh mining conditions.
The project focused on enabling additional cooling capacity while ensuring fast deployment, long-term durability, and consistent performance in a demanding underground environment.
Requirement
The Opportunity
BBE Projects, a specialist in mine refrigeration and ventilation systems across Africa, was tasked with
expanding cooling capacity at an operational mine.
As production demands increased, so did the need for enhanced underground ventilation. Without
sufficient cooling, the mine would not be able to:
- Maintain safe working conditions
- Support increased operational throughput
- Achieve targeted production levels
This created a clear requirement for a dependable, fit-for-purpose cooling solution.
The Challenge
The project presented a combination of operational and environmental challenges:
- Requirement for a minimum 15-year operating life
- Need for rapid construction and commissioning
- Operation in a dusty environment with poor water quality
- Critical dependence on cooling to sustain ventilation performance
Traditional concrete cooling structures were considered but ruled out due to long construction timelines and unnecessary structural lifespan for the application.
Solution
IWC (NEXT Cooling) designed and supplied a single-cell field-erected FRP cooling tower, engineered specifically for mining conditions.
Key features included:
- FRP (Fibre Reinforced Plastic) structure for faster construction and corrosion resistance
- NEXT’s proprietary splash grid fill, designed to be non-clogging
- High tolerance to dirty water and dusty environments
- Optimised design balancing performance, cost, and durability
This approach allowed for a significantly reduced build time while still meeting the client’s long-term operational requirements.
Process Integration
The cooling tower is a critical component of the mine’s refrigeration system:
- It cools water circulating through heat exchangers
- These heat exchangers drive the mine ventilation and cooling cycle
- The system functions similarly to a radiator, removing heat and maintaining stable operating temperatures
This ensures effective thermal management, enabling safe and efficient underground operations
Why IWC (NEXT Cooling)
BBE Projects selected IWC based on a proven track record of successful collaboration and delivery.
- Established working relationship
- Strong expertise in mining cooling applications
- Ability to deliver practical, fit-for-purpose solutions
- Alignment with performance, cost, and construction timeline
The Outcome
The solution delivered measurable operational impact:
- 6.5 MW of additional cooling capacity installed
- Improved ventilation and environmental control underground
- Enabled the mine to maintain and increase production levels
- Reduced risk associated with heat and insufficient airflow
Why This Project Matters
This project highlights IWC (NEXT Cooling)’s ability to deliver robust, efficient cooling solutions tailored to real mining conditions.
By combining smart engineering with innovative technology, such as non-clogging splash fill, IWC ensures reliable performance even in the toughest environments.
The result: cooling systems that don’t just meet requirements but actively enable operational growth.
