Case Study: Halton’s Success in the Tunnelling Sector
Tunnel infrastructure—whether for roads, railways, metros, or utilities—presents one of the most challenging environments for mechanical systems. In enclosed underground settings, ventilation is a life-critical system, serving not just comfort and air quality but also smoke extraction, fire containment, and emergency response. Ventilation equipment in tunnels must meet: - Stringent fire safety regulations - Extreme temperature and pressure tolerances - Low-leakage and corrosion resistance - Custom engineering for space-constrained, harsh environments
