Stack and Fan Systems: Increased Efficiency and Lower Noise
Stealth and efficiency: the potential to make fans and stacks up to 20% more efficient and 99% quieter*
Did you know it’s often possible to reduce the noise from stack systems and associated fans and to improve the efficiency 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 and downtime associated with fitting conventional attenuators, but the efficiency gains can often make stack and 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 systems from a few photographs and a smartphone video or noise recording.
What is the award winning technology?
Most stack noise problems are created by fans and efficiency is intimately related to fan noise: maximum efficiency occurs at the point of least noise (noise is created by 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 stack and fan silencers entirely, increasing the efficiency gains still further…

Silencing Performance and Costs
80% reduction in capital cost, 20% efficiency improvement*
Typically 10dB – 30dB tonal attenuation at a fraction of the typical 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.
*typical large fan, low frequency noise control applications versus typical conventional attenuators e.g. $1.25 million refinery project silencer cost reduced to $250k.
How to benefit from the technology
We can provide a free evaluation of the potential for our technology on any stack / fan system anywhere on the globe if you can provide us with photos and data from any smartphone by email or over the internet.
Remote control of stack and fan noise – anywhere
We have developed the technology to diagnose and solve stack / fan noise problems anywhere via the internet – without a site visit. This saves time and money and gives the whole planet access to our innovative power saving noise control technology. We’ve completed many very successful world-wide projects from our offices, including this oil refinery in the USA where capital costs were reduced from c $1.25 million to c $0.25 million…
