Railway heating systems

Flat tubular elements for switch points


During wintertime switch points might fail due to accumulation of ice and snow. This heating element is specially designed to solve these problems in the tough railway environment. It makes easier automatic control of railway points in winter and makes them reliable and independent of weather conditions.
The outer stainless steel sheath withstand corrosion and inner construction is resistant to mechanical shocks and vibrations. Electrical connections are totally sealed and protected from moisture penetration. Elektrotermija offers highly compressed flat tubular heating elements in various sizes, shapes, length, powers and materials. Standard elements are available from stock. 


  • Railway switch points
  • Tramway switch points
