Description
The SKW high-frequency warning siren with an anti-freeze system is a professional warning device designed for railway applications, compliant with the Regulation of the Minister of Infrastructure of 18 July 2005. It provides a clear, high-pitched audible signal with high audibility, effective in open spaces and areas with high background noise.
How does it work?
Compressed air flows through the sound generator, causing the diaphragms to vibrate. This produces high-frequency sound waves. The anti-freeze system maintains the temperature of the components at a level that prevents condensation and freezing.
Benefits:
+ High signal effectiveness – the high-pitched sound cuts through ambient noise more effectively, enhancing safety.
+ Operation in all conditions – the anti-freeze system eliminates the risk of freezing and moisture condensation, ensuring continuous operation in winter.
+ Compliance with railway regulations – the device meets applicable standards, enabling its seamless integration into railway systems.
+ Simple and durable design – the robust construction (horn + sound generator) ensures a long service life and low operating costs.
+ Effective pneumatic operation – the use of compressed air (490–980 kPa) ensures stable generation of sound waves at the required frequency.
