Since the low temperature of cold storage also varies, some reaching minus 20 or 30 degrees Celsius, for this electric door, how to prevent the door curtain guide rail from freezing and frost, the details are as follows.

    How to protect thermal insulation doors from freezing and frost

    1. Guide rail anti-freeze lubricant. The reason why the door curtain can open and close automatically smoothly and quickly without any lag is because the lubricant makes the connection between the guide rail and the zipper smoother. In order to prevent the formation of frost, choose anti-freeze lubricant.

     2. The guide rails are electrically heated. The guide rails of the thermally insulated rolling shutter door are equipped with electric heating wires. The guide rails are in a constant temperature state, which can prevent ice and snow from adhering and freezing, ensuring that the door curtain can run smoothly up and down the guide rails.

      3. The air curtain machine keeps blowing air, and the reason for frost on the door curtain is that water droplets and condensation often form on the door curtain. In order to prevent the door curtain from thawing, use the air curtain machine to keep the door curtain dry and dry the water droplets on the surface.
