Kahlenberg Industries

Kahlenberg Industrial Horns are powerful, high decibel signals backed by years of successful performance in coal yards, chemical plants, refineries, open pit mines and industrial facilities throughout the world. All Kahlenberg Brothers alarm products are designed to be operated indoors as well as in the most severe outdoor applications. They are simply constructed and extremely reliable resulting in a very low cost of use as compared to more complicated means of wide area notification. All of these horns are available for use with optional solenoid and manually activated valves as well as industrial timers.

Viewed here is just a sample of the air horn products available from Kahlenberg Brothers. Contact us for additional information on the full Kahlenberg Brothers product range.
