Coal wagon de-icing plant
The purpose of the coal wagon thawing room is to allow coal to be thawed from the wagon on the coal wagon thawing room. We achieve this by heating the walls of the wagon, which causes the coal layer to thaw from them. At the same time, we pay great attention to the temperature of the wheels, bearings and axles, which for safety reasons must not be heated to too high a temperature.
