Electric heaters with an automatic control system for the removal of snow and ice turnouts in winter

  • The most effective way to clean turnout of ice and snow has fallen or caused
  • Automatic control of heating
  • Ability to connect up to eight switches to one
  • control cabinet
  • High reliability design heaters, electrical
  • The installed capacity of 6.4 kW at a turnout
  • Stepped power regulation
  • Significant energy savings compared with existing analogues
  • Easy installation and use
  • Operating voltage 220 V


CNM system is designed to clean up the drop-down, or snow and ice caused rail turnouts in the winter.


CNM system includes a heater mounted on the outside of switches and automatic heating control system equipped with temperature sensors and precipitation. The system automatically turns on the heating in the presence of snow or ice translation, as well as under conditions favorable for their formation.


High Performance

The special shape of the contact surface of the heaters and the application of thermal interface material provides effective heat transfer from the heater to the body turnout.

mechanical stability

The design of the heating elements ensure reliable operation of the heaters in the conditions of vibration and mechanical forces associated with the movement of rail transport.

resistance to aggressive media and temperature changes

The elements of the system are made of corrosion-resistant materials to provide device performance upon exposure to atmospheric precipitation and the cycle-cal temperature changes.

Reliability, electrical safety, resistance to stray currents


The heaters have a high insulation resistance, ensuring reliable operation in the presence of stray currents associated with the operation of the electric vehicle.

To ensure that activities of automation in all the climatic conditions of the control cabinet housing has a performance of not less than IP-54.

The control system is equipped with circuit breakers and protective device power is turned off.

100% of the products are factory tested, including high voltage test in water.

Cost-effective heating system

Cost of energy consumption provided by the control system automatically changes the power of the heaters or completely breaking them coming from the environmental sensors, depending on the signal environment.

Universal application

Thanks to several sizes of heaters, as well as the possibility of manufacturing non-standard lengths of the heaters can transfer different types of heating and crossings, rails and other structural elements of the upper path.
