Estimating the term…
A gate arrangement for closure of a passageway between rooms with markedly different temperatures, such as the passageway of a freezer-room. Two door curtains are arranged parallel to one another, with each being capable of closing the passageway independently of the other. The door curtains have an abutting insulating air buffer between them, wherein at least one of the door curtains can be motor-driven at such a speed that it is suitable as a temporary high-speed closure between successive passages or transits therethrough. The two door curtains together with the insulating air buffer develop the insulation effect required to maintain the desired cooling temperature. Thus, frequent stocking of the room is possible while compromise of the climate in such rooms during stocking operations is kept to the minimum possible.
