Howden Technology Day 2025, held recently at Mintek, showcased groundbreaking advancements in mining ventilation, cooling systems, environmental pollution control, and clean energy solutions. The theme for this year was Advancing Engineering for a Sustainable Future.
The Technology Day is an exclusive event showcasing Howden’s full-spectrum engineering solutions. It features product exhibitions and case studies, highlighting their commitment to innovation across key industries. Attendees will learn about cutting-edge advancements in mine ventilation and cooling, environmental pollution control technologies, and growing opportunities in Liquefied Natural Gas (LNG) across Africa.
As global leaders in engineering, Howden once again demonstrated its commitment to driving innovation and sustainability across industries, offering attendees a unique opportunity to explore the latest technologies designed to address evolving industry needs.
Guest speaker Seggie Kistasamy, CEO of GrowthB Consulting and lecturer at Wits Business School, discussed the challenges and opportunities in the energy industry, including Africa’s 2025 economic outlook, cybersecurity threats, energy and water security, climate change impacts, economic stability, and South Africa’s commitment to a just energy transition.
Several presentations and case studies were presented during the event, including the making of an efficient mine ventilation system by Stephan Bergh, Mining Lead at Howden Middle East and Africa.
The presentation discussed the importance of designing an efficient ventilation system, optimising and automating it, and ensuring optimal ventilation to provide the best solution, following the design process. He also highlighted the importance of optimised ventilation to ensure the best solution is provided.
Howden’s Senior Application Engineer, Hernus Groenewald, highlighted the different technologies and innovative ways to integrate and create an optimal surface bulk air mine cooling solution that meets the challenges of modern-day inquires, especially those that include quick turnaround temporary cooling.
As the world moves towards a more carbon-conscious approach, the requirements and regulations around emissions control become more stringent. There are various methods of removing particles from a gas stream before to atmosphere.
The Senior Engineer in Air Pollution Control at Howden, Abri Bothma discussed the use of an Electrostatic Precipitator (ESP) and highlighted the main components of the ESP, how it looks and the potential causes of reduced collection efficiency.
