Point heating system

Product Application

Electric point heating system equipment is an indispensable system in the field of modern rail transit. The main function is to heat the movable parts of the turnout through automatic control means to melt the ice and snow at a specific location, thus eliminating the impact of rain and snow on the operation of the turnout, ensuring driving safety and operating efficiency.   
"RDK5-INSV electric point heating system" is the contribution of years of Keanda’s continuous research and development and field application of point heating in response to the actual needs of Chinese railways industry for point heating. The system has three control modes: automatic control, manual control and remote monitoring. It adopts a variety of heating elements and heating methods for outdoor turnouts to achieve the best heating effect and meet the requirements of various occasions.
