Trends in HVAC systems for mobile equipment in surface mining
The landscape of HVAC systems for mobile equipment in surface mining and quarrying sectors has evolved significantly over the past decade. The shift has been towards more robust systems capable of withstanding the harsh conditions typical of these operations. Brenton Spies, Managing Director of Booyco Engineering, says that trends in HVAC systems have focused on operator safety and comfort, system reliability and environmental considerations.
“Over recent years, there has been a pronounced focus on operator safety and comfort,” Spies says. “The classification of climate as a Class A hazard underscores the importance of providing operators with comfortable working conditions. Ensuring a safe and comfortable environment is not just about individual wellbeing but also about enhancing productivity.”
“Reliable and effective HVAC systems are crucial in maintaining a safe working environment around the clock, and Booyco HVAC solutions play a vital role in improving working conditions, whether in extreme heat or cold,” he says. By ensuring a comfortable working environment, HVAC systems help maintain cognitive awareness among operators, preventing accidents.

Booyco HVAC systems assists in preventing serious medical conditions that could jeopardise an operator’s health and safety and by combining HVAC systems with air filtration systems mitigates the risk of respiratory illnesses by removing harmful gases and particles from the operator cab. Booyco HVAC systems are designed to integrate seamlessly with Sy-Klone air filters, enhancing air quality. Booyco Engineering is an authorised distributor of Sy-Klone air filters in southern Africa.
Spies explains that maintaining uptime of equipment on a surface mining site is critical for minimising operational costs, especially given the current pressure on commodity prices. “Good working conditions are integral to this. Operators have the right to stop working if the HVAC system in their cab becomes dysfunctional, potentially causing significant interruptions to mining operations. This, again, reinforces that reliable HVAC systems are essential to ensure continuous operation.”
Mining environments are inherently extreme, with operations often located in remote areas with severe weather conditions. Dusty operating environments are common, despite dust mitigation efforts. Booyco HVAC systems are engineered to withstand these harsh conditions, with attention to detail ensuring the systems can handle extreme vibrations when traversing rough terrain. Quality components are selected during the design phases to ensure reliable performance under these extreme conditions.
“Ongoing maintenance of HVAC systems is just as crucial as selecting the most appropriate system for an application to ensure reliability, and we offer maintenance contracts and Man on Site (MOS) options that facilitate preventative maintenance and ensure optimal uptime of our HVAC systems, ensuring maximum fleet uptime.”
A notable trend in recent years is the move towards more environmentally friendly refrigerants. Supporting the sector’s commitment to reducing its carbon footprint, Booyco Engineering has developed a fully integrated HVAC anti-idle auxiliary power unit (APU). This innovative solution significantly reduces diesel consumption during operational idle times, leading to a reduction in operating costs.
“The evolution of HVAC systems for mobile equipment in surface mining reflects a comprehensive approach to tackling the industry’s unique challenges, and Booyco Engineering has been at the forefront of these developments with continued emphasis on robust design, operator safety and comfort, reliable performance and environmental responsibility,” Spies says. “By continuously innovating, we ensure that operators work in safe, comfortable environments, enhancing productivity and operational efficiency across the mining sector.”
