Project Background: An 80,000㎡ cold chain sorting warehouse with an internal temperature of -18℃. The original old door had poor sealing and slow opening and closing, resulting in:

• Serious cold air leakage, leading to high energy consumption costs of the cold storage

• Door freezing and jamming, affecting 24-hour uninterrupted operation

• Low cargo traffic efficiency and logistics congestion during peak hours

Product Solution: Customized high-cold insulated industrial sliding door with core configurations:

• 60mm thick polyurethane insulated door panel, with a sealing heat leakage rate ≤0.5W/(m·K)

• Servo motor + low-temperature heating device, opening and closing speed of 2.8 seconds, preventing freezing and jamming

• Double-layer EPDM sealing strip + loading and unloading platform linkage, forming a complete sealing system

Implementation Effect:

• Cold storage energy consumption dropped by 41%, saving about 170,000 yuan annually in cold air leakage costs

• Door trouble-free operation rate reached 99.8%, adapting to 24-hour uninterrupted operation

• Single cargo passage time shortened from 35 seconds to 10 seconds, traffic efficiency increased by 120%
