Acoem Tunnel Sensors

is a leading specialist in the design and manufacture of advanced technology instrumentation for tunnel atmosphere monitoring.

We design and manufacture our own analysers specifically for pollution monitoring in the traffic tunnel environment.

Our analysers are designed to be combined in a modular fashion, offering the flexibility to create monitoring systems specifically adapted to the requirements of individual tunnels.

Our tailored range – designed to meet your needs

We design, manufacture, commission and maintain a complete range of road tunnel monitoring systems. Our instruments communicate with tunnel ventilation systems, automatically instructing them when to turn on critical jet fans due to changes in internal atmospheric conditions.

Superior road tunnel monitoring solutions

As global populations grow and existing road infrastructure become more congested, urban planners are increasingly turning to underground road tunnel networks to support smart city and regional expansion. Accurate and efficient monitoring of atmospheric conditions in tunnels using accurate tunnel sensors is critical to ensuring the safety, health and wellbeing of those who use them. It is mandatory for regulatory compliance and integral to maintaining the longevity of the asset for road owners/operators.

New build tunnels

We work collaboratively with ventilation contractors to ensure we commission the best possible road tunnel monitoring equipment to meet each project’s specifications, whether that is a fully integrated measurement system, a network of instruments or a single sensor or component. We offer flexible solutions that allow for the nuances of each project.

Tunnel refurbishments

When tunnel infrastructure ages, structural components and auxiliary systems need to be upgraded. Every 10 years, tunnels generally undergo major refurbishments, including replacing electronics, lighting, controls, fire alarms and measurements systems.
Our team of specialists works closely with tunnel operators and their contractors to ensure that all replacement sensors and integrated systems are tailored to meet individual requirements and offer the most advanced technology available – providing accuracy and ongoing efficiency.
