The soft curtain quick cold storage door has a simple design and is designed with a heating antifreeze device to ensure smooth and efficient operation of the product in a low temperature working environment. The structure incorporates the function design of collision avoidance recovery. When the door body is accidentally impacted, it deviates from the track and automatically repairs the return position during the ascent process. This structure not only facilitates the safe and smooth operation of the door body, but also operates more than 150,000 times a year without failure. It extends the life of the product while reducing component replacement and maintenance costs.
Such rapid door is specially designed for freezer, cold room, or cool room. It is made from 30 mm thick thermal insulated,sandwich curtain, and with all-round heating device to avoid frozen. Thus it can work well in low temperature like -25 º C. It can reduce thermal transmission by fast opening and closing, and thermal insulated door curtain. For each door, it can help customer save energy cost by at least USD 8000 every year,than traditional normal speed cold room sliding doors.
