This Low Temperature Cold Storage Warehouse is specifically designed for refrigeration applications ranging from 0 °C fresh-keeping to −18 °C freezing. It features a core made of high-density polyurethane rigid foam cold-storage panels, double-sided and clad with 0.4–0.6 mm color steel or stainless steel plates. The tongue-and-groove splicing system, combined with a triple sealing structure, ensures a core material with a closed-cell rate of over 97% and a thermal conductivity as low as 0.022 W/(m·K).
Coupled with low-temperature-resistant EPDM rubber sealing strips and a bottom hydraulic lifting anti-leakage panel, the unit achieves an airtightness rating of Class 13, effectively preventing cold loss and contributing to over 30% energy savings.
The Low Temperature Cold Storage Warehouse is equipped with DL/DD/DJ series air coolers and fully enclosed units, featuring brushless EC motors, reinforced aluminum-alloy impellers, and fully enclosed scroll compressors from well-known brands. Its energy efficiency ratio significantly surpasses that of traditional models, reducing energy consumption by up to 40%.
The system operates continuously and reliably for 24 hours, with a temperature control accuracy of ±0.5 °C, and achieves 40–50 air changes per hour to ensure rapid and uniform cooling.
The Low Temperature Cold Storage Warehouse has a compressive strength of ≥200 kPa, capable of withstanding a pressure of 3 tons/m², and meets a B1 fire rating. It uses food-grade, environmentally friendly materials, containing no formaldehyde and posing no ozone-depletion risk. An IP68 protection rating makes it suitable for high-humidity environments.
Modular installation shortens the construction period by approximately 40%. Integrated features include infrared light-curtain anti-pinch protection, multiple safety protection mechanisms, and intelligent fault warning functions. With a service life of 15–20 years, the unit is widely used in food refrigeration, pharmaceutical storage, supermarket cold-chain logistics, and other applications, providing long-term quality assurance for stored goods.
