Glyn Pierce-Jones will become managing director, overseeing product certification and sales and marketing.

Lee Pierce-Jones becomes operations director, with responsibility for production, quality and research and development.

The elder Pierce-Jones, who said his sons would help take the company in a new direction, will serve as chairman.

“This is an exciting time for Trolex as we build on the company’s firm reputation over the last 50 years as a world leader in the design and manufacture of sensors and systems for tunnelling, mining and hazardous industry,” Glyn Pierce-Jones said.

“We are planning a rapid expansion and growth program and we believe we have the potential to triple sales over the next three to four years.”

Already a global brand, Trolex has taken on a new brand image this year across all areas of the company, including a newly formed industrial division to expand into that area parallel with mining.

Trolex, established in 1960, provides gas detection and environmental monitoring systems and equipment to the mining, tunnelling, gas recovery and rail sectors.
