The GY and GY20 heater

1000W heater

External stairs are not only exposed to extreme sunlight and heavy rain, but also to snowfall and long lasting frost. So the escalator is not frozen, the heating elements are installed within the step belt and under the two comb plates, which can be switched on manually, or with temperature sensor. The calculation of the necessary total output KW of the heating elements is a function of the conveying length of the escalator.
