Aluminum spacer, PVC spacer and traditional warm edge spacer hollow insulated glass cooler/refrigerator door have dissatisfying sealing performance. The argon filled inside the cavity of insulating glass unit (IGU) cavity quickly leaks or lose performance. After 1-2 years,argon percentage drops to below 80% and glass will lose its heat insulation and energy saving effect.

Because of the poor sealing performance, water vapor and moisture will soon penetrate into/enter the hollow glass cavity, causing condensation/dew in the glass cavity, evening forming water droplets, and the glass door will lose energy saving performance and has to be replaced with new ones.

To overcome this argon leak problem, we imported flexible ESG spacer insulated glass machine from Europe, and design a new generation of insulation glass and doors for upright beverage display cooler/freezer.
