Safety is key in monitoring mining environments

ACTOM Industry, which is well known for its expertise in mine winder hoists within the ACTOM group, is expand ing its portfolio with the introduction of fire detection and safety solutions designed for explosive atmospheres. Leveraging its advanced power electronic drive, control, and switchgear technology, ACTOM Industry continues to lead the industry in providing enhanced safety and protection in hazardous environments. Intrinsically safe fire detection systems Janna Kapp, General Manager at ACTOM Industry, says the company’s fire detection systems, rigorously tested and certified by the South African Bureau of Standards (SABS) to meet the stringent criteria of SANS 1515, are intrinsically safe for use in explosive atmospheres. This approval underscores ACTOM Industry’s commitment to safety and quality. Its comprehensive range of fire detec tion systems 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, consolidating its position as the premier pro vider of safety solutions. The acquisition gives it exclu sive 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. Using the reliable VORTEX method, it ensures precise measurements, independent of small particles, to ensure optimal performance even in dusty or high-moisture conditions. The CT-8000 S3 is Vanguard Instruments’ fourth gener ation EHV (Extra High Voltage) circuit breaker analyser. The CT-8000 S3, with integral 200 A source, is available with three or six contact timing channels. It can fully an alyse a circuit breaker’s performance by measuring the main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes. Another outstanding feature of the CT-8000 S3 is the ability to perform dynamic resistance tests on cir cuit breaker contacts. It is also capable of performing dual side grounded tests on circuit breakers, enhancing safety and accuracy by grounding both sides of the ap paratus during testing and helps to reduce test set up time. As well as the USB computer interface and flash drive interface, the analyser can be supplied with an optional Advanced digital circuit breaker analyser

ACTOM Industry supplies a range of intrinsically safe fire detection systems to support safety in mining environments. In underground mining, proper air circulation is vi tal for safety. The ACTOM Air Velocity Detector quickly detects any decrease in airflow, alerting operators with in seconds through SCADA systems. The detector is housed in a robust metal enclosure to withstand impacts during handling and minimise the effects of crossflow, ensuring consistent and reliable performance. Extensively tested in the South African mining sector, the Air Velocity Detector has proven to be the top choice for underground applications. It delivers a measurement accuracy of about 89% and is unmatched in durability and precision. Its resilience against water mist and dust minimises maintenance demands, ensuring continuous safety in hazardous environments. With its advanced solutions delivering proven per formance, ACTOM Industry confirms its commitment to safety in industrial settings.
