Heating, ventilation and air conditioning (HVAC) supplier Booyco Engineering, with over 40 years of expertise, is a leader in climate control solutions for South Africa’s mining and quarrying sectors, where dust, heat and toxic gases pose major health risks. As the Mine Health and Safety Act mandates safe working conditions, the industry is shifting from reactive to proactive management of environmental hazards, with increased focus on monitoring and controlling worker exposure.

In these demanding environments, machine operators often work in enclosed cabs for long periods. Booyco Engineering’s HVAC systems are engineered to safeguard operator health while ensuring compliance with global standards, including ISO 23875, which governs cab air quality. This standard requires the delivery of fresh filtered air with positive pressurisation to prevent contaminated air ingress and effective control of CO2 levels.

Achieving these conditions in harsh mining and quarrying environments is technically complex owing to high dust loads, diesel fumes and extreme temperatures. Booyco Engineering’s bespoke HVAC solutions overcome these challenges through advanced filtration 
and pressurisation technologies. The systems incorporate Sy-Klone filtration to provide clean cooled air while maintaining correct pressure and limiting CO2 buildup.

Beyond air conditioning, these are fully integrated environmental control systems that monitor cab air pressure, particulate concentrations and CO2 levels in real time. The data can be downloaded and analysed, allowing mines to track operator exposure, verify compliance 
and strengthen health and safety management.

This proactive approach supports environmental, social and governance objectives and enhances operational efficiency. By reducing downtime linked to overheating or blocked filters, Booyco Engineering’s systems improve productivity and equipment performance. Through continuous innovation and alignment with international safety standards, the company enables mines and quarries to maintain compliance, protect their people and optimise overall performance.
