Our Story

Where it all began

RTS was established in 1999 by Jan Erasmus in order to develop and improve the safety of miners working underground by supplying a unique range of environmental gas monitoring equipment to coal mines in South Africa.


In 2018, RTS decided to expand its horizons and embrace a new chapter in its history. The company transitioned its marketing rights to Radio Transmission Services Electronics PTY Ltd (RTSE). This transformation marked a significant milestone as RTS became a Level 2 BBEE (Broad-Based Black Economic Empowerment) company. We are proud to be 49% black woman-owned and 51% black-owned in total, contributing to South Africa's growth and transformation.


Over the past four years, RTSE has experienced exponential growth. Our team now comprises four dedicated Directors and an additional 13 employees, enabling us to provide a comprehensive range of services. Beyond supplying top-quality equipment to mines, we have expanded our expertise to include installation, maintenance, and consulting services. RTSE has become synonymous with safety and innovation within South African coal mines. Our history is a testament to our unwavering commitment to making mining safer for humans and the environment.
