Cold storage insulated rapid rolling door  

Cold storage insulated rapid rolling doors are installed in more and more cold rooms, cold chains, cooler room, refrigeration warehouse and also temperature control workshop with air conditioners.  It is energy saving by reducing cold air loss and thermal transduction. With fast opening and close speed, cold room insulated rapid rolling door can finish a running cycle in only several seconds. People and vehicles will be able to pass the door in short time. This obviously lower cold air loss volume. When you install a regular traditional cold room sliding door, it is difficult to keep it closed when there is a lot traffic. So workers will tend to keep the sliding door open in long time, which lead to big cold air loss. This situation will be changed when you install a cold storage insulated rapid rolling door. It will quickly open and close automatically after people or vehicle passing. …
