Hexagon Electrical has expanded its manufacturing and service capabilities to meet growing demand for customised, high-performance specialised electric motors for heavy engineering, hazardous industrial and mining applications.
The company, based in Brakpan, Gauteng, manufactures flameproof and non-flameproof equipment, combining mechanical precision, electrical expertise and design innovation to deliver robust, energy-efficient certified solutions, tailored to exact customer requirements.
“Our broad product portfolio comprises motors and transformers, enclosures and switchgear, ventilation fans, scrubber fans and auxiliary equipment, as well as a full range of flameproof equipment compliant with SANS 60079 standards,” says David Dyce, CEO, Hexagon Electrical. “The range of specialised Hexagon motors includes dual kW and dual speed AC motors, slip ring motors and water-cooled flameproof motors. Also in our portfolio are flameproof or standard winch and traction motors, as well as standard or flameproof pad mount motors for heavy-duty mining applications.”
Dyce highlights that all motors are offered with optional customisation in voltage, mounting, shaft configuration and thermal protection. The company also designs, supplies and services transformers, enclosures, ventilation equipment and auxiliary components for integrated system deployment.
Hexagon Electrical equipment is robust, engineered to ensure high performance and optimum safety in critical applications, including ventilation in hazardous areas, chemical processing, materials handling and in underground mining.
“With our in-house design, manufacturing and testing facilities, our highly skilled team offers a complete lifecycle service, including system design, motor rewinding, mechanical refurbishment, electrical testing and final certification,” Dyce adds.
The company’s recent investment in test infrastructure enables it to evaluate motors at full load up to 460 kW and 6.6 kV. Flameproof inspection is conducted by accredited inspectors and all products undergo mechanical and electrical assessments prior to final assembly. A dedicated vacuum pressure impregnation (VPI) system and dual varnishing process ensure quality, durability and performance in extreme operating environments.
The manufacturing facility is equipped with four production bays, each with dedicated lifting capabilities ranging from 5 to 25 tonnes. Machining, lamination punching, coil winding, and dynamic balancing are all undertaken in house, using modern equipment, including a 460 kW Schenk dynamometer and high-voltage test systems.
The manufacturing process is supported by proprietary design software developed in collaboration with the University of Witwatersrand, enabling advanced simulation, stress verification and application-specific winding design.
The company’s operations are underpinned by environmental and safety standards and are fully compliant with SABS, SA Flameproof Association, SEIFSA, MASC and ISO technical standards. Motors and control systems are assembled in accordance with SANS 10242 and inspected against client specifications prior to dispatch. Each unit is supplied with a full data book, including balancing certificates, electrical test reports, records of the repair history and traceable calibration records.
Hexagon Electrical is led by David Dyce, whose technical background and commitment to quality assurance continue to drive the company’s focus on performance, reliability and long-term customer support. As part of Montsi Investments, Hexagon maintains a strategic focus on industrial resilience, manufacturing new equipment and providing repair services to sectors where downtime and failure risk carry high operational costs.
