Types of connection

Electric connection

This steel ladder radiator is electric compatible and can be equipped with an electric rod with a temperature limiter set to 85°C, which protects the device against overheating. Radiators are factory pre-filled with an antifreeze mixture with a freezing point of -5 ° C.

You can choose from more types of thermostats to further set up the heating temperature, more about
