Within this dossier of case studies on the successful internationalization of Asturian companies promoted by ASTUREX, we present Zitron, the world leader in ventilation systems. Zitron has generously shared its time, work, and experiences with us to build a case study that highlights its international strategy and its global reach. Zitron is shaping the global landscape of ventilation in mines and underground infrastructure from Asturias: from the Doha Metro and the Grand Paris Tunnel to mines in Australia and South Africa and highways in Saudi Arabia and Vietnam.
