But thus in any situation revolving doors, to be exact their shutters, block a direct stream of air from the street to the room, allowing to keep warmly inside even in hard frosts. In other words, revolving doors don’t demand additional installation of the platform without what it is impossible to do in any other case.
Unlike other types of automatic doors and even unlike analogs of other producers, rotary doors can be used also as an emergency exit, thanks to the unique mechanism of folding of shutters.
