How to update the current (failing) noise risk management process to make it much more effective – and self-financing Noise Induced Hearing Loss claims of £400,000,000 per annum show that thousands of people are suffering hearing damage, most of which could be avoided by changing the way risk management is is carried out. A simple, innovative approach that dramatically improves the effectiveness of noise risk management was described at the BOHS
Stack and Fan Systems: Increased Efficiency and Lower Noise
Stealth and efficiency: the potential to make fans and stacks 20% more efficient and 99% quieter*
Did you know it’s often possible to improve the efficiency of industrial fan and stack systems and to reduce the noise using innovative aerodynamic technology instead of silencers? The technique can even allow you to remove existing silencers for yet greater efficiency gains (up to 20% or more). This approach is not only a fraction of the cost of silencers, but the efficiency gains can often make fan noise control projects profitable. Even if noise is not an issue, system efficiency can often be significantly improved as an end in itself. Moreover, we can evaluate the options for most fan systems from a couple of photos and a smartphone video or noise recording.
What is the award winning technology?
Fan efficiency is intimately related to fan noise: maximum efficiency occurs at the point of least noise (noise is energy wasted as turbulence). F1 car and aircraft designers develop sophisticated aerodynamic aids that enhance performance by controlling air flow. We’ve developed similar technology for fan systems to make them as efficient as possible. We model the system and design retro-fit aero-inserts for existing fans to reduce noise at source. Where applicable, it is also often possible to dispense with conventional silencers entirely, increasing the efficiency gains still further… The same approach is equally applicable to entire fan / stack systems.

Silencing Performance and Costs
80% reduction in capital cost, 20% efficiency improvement*
Typically 10dB – 30dB tonal attenuation at a fraction of the capital cost of conventional silencers and with a fraction of the down-time required for installation (see example here). We have also developed a range of innovative complementary silencing techniques that address higher frequency broadband noise without compromising efficiency.
Partner with us to benefit from the technology
We have been setting up partnerships with organisations across the globe to provide the technology as a very high added value complementary service for existing (or new) partner clients.
