A range of fire detection and safety solutions designed for explosive atmospheres aims to ensure enhanced safety and protection in hazardous environments. 

ACTOM Industry, specialists in mine winder hoists within the ACTOM group, has expanded its portfolio with the introduction of its fire detection systems.

Tested and certified by the South African Bureau of Standards to meet the criteria of SANS 1515, the systems are said to be intrinsically safe for use in explosive atmospheres.

The range includes:

• Air velocity detectors
• Carbon monoxide detectors
• Methane detectors
• Particle smoke detectors

In 2023, ACTOM Industry acquired sole ownership of the Safdy air velocity detector and the Safdy methane detector, which gave it exclusive rights to manufacture, market and distribute these products.

Formerly known as the Safdy flow meter, the ACTOM air velocity detector features a solid-state airflow sensor designed specifically for monitoring airflow rates in challenging environments typical of mining operations. Utilising the VORTEX method, it is designed to ensure precise measurements independent of small particles to provide optimal performance even in dusty or high-moisture conditions.

“In underground mining, proper air circulation is vital for safety. Our air velocity detector swiftly detects any decrease in airflow, alerting operators within seconds through supervisory control and data acquisition, or SCADA, systems,” says ACTOM Industry GM Janna Kapp.

Enabling real-time monitoring, the unit is housed in a robust metal enclosure, allowing it to withstand impacts during handling and minimising the effects of crossflow, to provide consistent and reliable performance.

The company notes that its solution has been extensively tested within the South African mining sector and boasts an accuracy rate of approximately 89%. Its resilience against water mist and dust helps minimise maintenance demands and is integral to ensuring continuous safety in hazardous environments.
