in its fans . Given the stringent regulations surrounding noise levels in mining operations , the company has developed effective attenuators to minimise sound level output . This commitment to compliance extends to their HardLine ducting , which offers significant energy savings compared to traditional PVC ventilation ducting . The use of engineered polymers for duct construction enhances safety through anti-static and fireretardant properties , crucial for underground environments .
One of the standout benefits of the HardLine ducting is its ease of installation . Unlike traditional galvanised steel ducting that requires bolts and spanners , ABC ' s ducting is designed for quick assembly , making it user-friendly for mine workers . The lightweight material is also recyclable . At end of lifecycle , the ducting can be repurposed into various products , for example furniture and school containers which can then be donated . This initiative aligns with corporate social investment plans that many mining houses are adopting to give back to the communities affected by their operations . The company ’ s ability to recycle approximately 10-15 % of its materials back into production not only minimises waste but also supports local economies .
While the initial implementation costs may be higher than traditional galvanised steel ducting options , the company emphasises the long-term benefits associated with operational savings and energy efficiency .
“ Central to these savings is the advanced friction factor of ABC Ventilation Systems ' HardLine ducting materials . Unlike conventional ducting , which can have significant friction losses , our engineered polymer ducts provide a smoother airflow , allowing for more efficient air transport . This design enhances laminar flow , reducing turbulence and enabling the air to travel further , up to 60-70 % more distance , compared to traditional options . This efficiency translates into lower energy costs over time , making the investment in the product economically advantageous in the long run ,” says Van der Bank .
Pearce adds : “ To support local economies and mitigate supply chain issues , ABC Ventilation Systems has committed to sourcing raw materials locally and establishing domestic manufacturing processes . This strategy not only reduces reliance on fluctuating international shipping but also supports job creation and economic development within South Africa . Our vertically integrated structure ensures greater control over production , leading to improved product quality and consistency .”
He notes that by maintaining dedicated on-site teams at major mining operations , the company ensures that clients receive immediate technical support and training . “ This handson approach facilitates skills transfer and helps clients maximise the benefits of ABC Ventilation Systems ’ products . The company ’ s commitment to local operations extends beyond client support . We have established a comprehensive network across Africa , with trade distributors in numerous southern African countries , and are part of a global joint venture that includes operations in South America , Canada and Australia . This extensive reach allows us to provide consistent service and training , ensuring that the quality of support remains high across different regions ,” adds Pearce . RACA
