Acoustic Cleaners - 100% Effective – Proof Positive!

I firmly believe that not only do we design and build:-

• The best quality acoustic cleaners
• Offer the widest range of models
• With the most powerful and consistently reliable performance

but we also have the finest technical back-up and R & D department. Let me give you an example of why I can make this claim.

One of the most frequently asked questions is:
Will your Acoustic Cleaner Damage My Steel Boiler Or Concrete Silo?
Well the answer is most affirmatively - NO
However can we prove it – YES

So let me show you the results of one of our many extensive field trials which proves that our powerful sonic waves, at the frequencies we use, that is between 420 Hz and 60 Hz, are totally absorbed by the material to prevent particulate build up and maximise material flow.

One of our flour mill clients had a series of concrete flour silos and they were having a lot of problems with flour building up on the side walls, then collapsing on mass and spilling out like water from the silo dischargers. They were very keen to install our acoustic cleaners/sonic horns, however they had great concerns that the sound waves would be absorbed by and damage the concrete silos.

In their field trial we measured both the constant existing vibrations that occur within and around the concrete silos, such as fork lift truck passing by or electric motor vibration etc. We did this by fitting accelerometers to the silo walls. We then placed a sound meter some 10 metres/33’ down the silo and the silo was filled with flour. Finally we installed a Model PAS-75 acoustic cleaner/sonic horn on top of the silo and sounded for a few seconds at periodic intervals.
The graph below measures Frequency along the X axis and dB along the Y axis.

The orange graph is measuring the already occurring vibrations of the silo picked up by the accelerometers and the blue graph is recording what the sound meter, buried deep within the flow is picking up. You can clearly see that the sound meter is clearly recording a high burst of acoustic energy at 75 Hz and again at 150 Hz (2 x 75 Hz). You will also clearly see that none of these powerful ‘debonding’ sonic sound waves have been absorbed into the concrete silo structure.
This is just one of many similar field trials which we have carried out on silos, boilers, baghouse filters and ESPs.

Proof positive that the power of our acoustic cleaners is 100% effective in debonding the material with 0% effect on the structures.

Sometimes we forget that our acoustic cleaning technology is so innovative that many companies within key industries around the world still don't even know it exists! So when companies approach us for a solution to their material flow problems and they have never heard of the technology before, they can be understandably reticent about making the capital investment.

We can quote them excellent case studies of course with great, proven success and that sometimes works - such as the client who came to us with a waste to energy boiler problem and did not realise that there was an alternative to the aggressive cleaning system of steam soot blowers. They purchased an acoustic cleaning system from us and have not looked back, benefiting from ash build up prevention, significant cost savings and improved performance in terms of heat transfer.

However, even a good case study and client referral is not always enough. So I made the decision to put my belief in the product on the line and allow companies to enter into a rental agreement. This way they can test the product directly and have their engineers witness first hand the startling difference in performance and savings that acoustic cleaners offer.

This idea has proven a great success to date and our acoustic cleaners have gone out on rental all over the world resulting in extra sales within a matter of a few months. Recent acoustic cleaner rental agreements we have agreed to include:

• for hopper cleaning operations at a port in South Africa (PAS-350 model)
• for silo cleaning at a chemicals plant in Sweden (PAS-230 model)
• for hopper cleaning at a major British port (PAS-75 model)
• for rotary dryer cleaning at a British chemical plant (PAS-230 model)
