To quote the US Department of Energy:
"In the U.S., compressed air systems account for $1.5 billion per year in energy costs, and 0.5 percent of emissions. Many industries use compressed air systems as power sources for tools and equipment used for pressurizing, atomizing, agitating, and mixing applications. Optimization of compressed air systems can provide energy efficiency improvements of 20 to 50 percent."

Leak repair may be the least expensive method to control compressed gas costs. We use an ultrasonic sound detection instrument to find your leaks. Once the leak is located, a serialized tag is hung to help maintenance personnel find it for repair. Leak location can be done anytime the system is in service. We will also provide repair workorders for each leak and a summary of all leaks found.

The real power of this technology is its ability to quickly locate leaks by scanning a general area. Using ultrasonics we can find leaks in both compressed gas (air, CO2 , Ammonia, steam, etc.) and vacuum systems. In addition, valve leak through, high voltage arcing and corona, and rolling-element bearing problems all generate ultrasound.
Ultrasonics is simple in principle. As gas passes through an opening, it creates turbulence. This turbulence generates high frequency sound waves. By using the appropriate instrumentation, this sound can be heard and measured. A major advantage of this method is that very small leaks, which other wise would go unnoticed, can be easily detected. Though each of these leaks may be very small, in aggregate, they represent a large leak. And a large cost. |
