Each tunnel engineering project presents you with unique challenges that our Tunnel Ventilation attenuators and noise control solutions are perfectly designed to overcome.

Caice Tunnel Ventilation Attenuators

Guaranteed noise reduction and years of low maintenance with our Tunnel Ventilation, we have developed a robust, modular system for our Attenuators that have been put to use in prestigious global Tunnel Ventilation projects, are performance-tested and fully compliant with BS EN ISO 7235: 2009.

Never worry about integrating products from different manufacturers again, as our Acoustic Louvres, Enclosures and wall linings are all designed to work together with our Tunnel Attenuators in one complete system.

A turnkey solution that is perfect for your project

Our team of Tunnel Ventilation experts work hard to understand you and your project challenges and a turnkey solution can encompass an acoustic survey, technical design, structural design, project management and manufacture, ensuring that every element of your project is covered.

Caice Tunnel Ventilation

Our Tunnel Attenuators quieten the ventilation systems, which not only provide fresh air for weary train passengers or drivers using the tunnel, but they also create a safe, comfortable environment for users. Whilst the noisy plant and equipment above is prevented from disturbing neighbours and spoiling the environment.

Reducing Installation Time for authorised personnel

Your project team will find installing our Tunnel Ventilation systems a simple and effective task as we coordinate the design of our products to allow suitable offloading and distribution with specific instructions, as well as detailed drawings that reduce site installation time.
