Industry Applications
01
Food Factory Industry
Food Factory Industry
Cold storage doors are key equipment for maintaining strict temperature control, hygiene standards, and operational efficiency in the food industry. Taking the chain enterprise Holiland as an example, after upgrading to high-airtightness polyurethane cold storage doors, the temperature fluctuation inside the storage was reduced from ±2.5°C to ±0.8°C, significantly decreasing the frequency of compressor start-stop cycles and saving over USD 1500 in annual electricity costs. Additionally, the door body is made of anti-bacterial and anti-mold materials with a seamless structural design, effectively eliminating sanitary dead corners, enabling the company to successfully pass the BRCGS Food Safety Standard certification during third-party audits. It is evident that high-quality cold storage doors are not only a temperature barrier but also a crucial support for ensuring food safety and reducing operational costs.
02
Logistics Industry
Logistics Industry
Modern logistics centers demand both efficiency and stability, with door system performance directly affecting warehouse operations. Industrial sectional doors offer rapid response and superior insulation, enabling fast cargo flow without compromising temperature control. At JD.com's fresh food cold chain center—handling over 30,000 orders daily with doors opening every three minutes—upgrading to polyurethane-core sectional doors with double-layer seals reduced temperature fluctuation from ±2°C to ±0.5°C, cut daily refrigeration runtime by nearly two hours, and saved over RMB 80,000 annually per warehouse. The doors' vertical lift design saves aisle space, improving forklift efficiency and boosting pallet handling by over 20%。
03
Pharmaceutical Industry
Pharmaceutical Industry
Pharmaceutical storage demands stringent temperature control and cleanliness. As core environmental control equipment, cold storage doors must deliver excellent thermal insulation and hygiene assurance. High-quality doors minimize temperature fluctuations, preventing drug efficacy loss, while their anti-bacterial, seamless design complies with GMP standards, eliminating cross-contamination risks. At a vaccine facility, upgrading to professional cold storage doors improved temperature stability by over 30%, enabling consecutive years of quality audit approval and maintaining a product qualification rate above 99.9%.
04
Factory Warehouse
Factory Warehouse
High-speed doors are core equipment for improving loading/unloading efficiency, cargo turnover speed, and passageway safety in factories and warehouses. Made of high-strength PVC fabric, they offer durability and wear resistance. With opening speeds of 1.5–2.0 m/s, they significantly reduce waiting times, greatly enhancing efficiency. The PVC curtain, combined with multi-layer sealing, reduces energy consumption by 20%–30% compared to traditional doors. Safety sensors enable automatic reversal upon obstruction, ensuring safe passage for personnel and vehicles.
