Description
The SKN low-frequency warning siren with an anti-freeze system is a reliable warning device designed for railway applications, meeting the requirements of the Regulation of the Minister of Infrastructure of 18 July 2005. It guarantees effective sound signalling even in extreme weather conditions.
How does it work?
Compressed air fed into the sound generator causes the diaphragms to vibrate, generating acoustic waves of a specific frequency. The anti-freeze system maintains the optimum temperature of the components, eliminating the risk of failure caused by freezing..
Benefits:
+ Reliability in all conditions – the built-in anti-freeze system prevents moisture build-up and the freezing of key components, ensuring continuous operation in winter.
+ Powerful warning signal – a low-frequency sound with a long range improves safety on and around the tracks.
+ Compliance with railway regulations – the device meets applicable standards, enabling its seamless integration into railway systems.
+ Simple and durable design – 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 the stable generation of sound waves at the required frequency.
