Changzhou, Jiangsu – May 23, 2026 – Changzhou Yijing Refrigeration Equipment Factory, a professional manufacturer of cold storage insulation panels since 2003, has officially launched its Insulated Cold Storage Panel No.3, a high-performance PU sandwich panel designed to meet the growing global demand for energy-efficient, durable, and eco-friendly cold storage solutions. The new product targets low-temperature freezers, chilled warehouses, and pharmaceutical storage facilities, offering superior thermal insulation and structural reliability.
Insulated Cold Storage Panel No.3 features a premium CFC-free rigid polyurethane (PU) foam core with a density of 40±2kg/m³ and thermal conductivity of ≤0.022W/(m·K), ensuring exceptional heat resistance and minimal energy loss. The panel’s facings are available in 0.426–0.6mm pre-painted galvanized steel (PPGI), 304/316 stainless steel, or embossed aluminum, providing excellent corrosion resistance and food safety compliance. Its innovative interlocking cam-lock joint system enables airtight and watertight assembly, reducing cold leakage by 20–30% compared to traditional panels.
Standard specifications of Insulated Cold Storage Panel No.3 include a width of 960mm, thickness options of 50mm, 75mm, 100mm, 125mm, 150mm, and 200mm, and customizable lengths up to 12 meters. The panel operates efficiently in temperatures ranging from -40°C to +10°C, making it ideal for storing seafood, meat, fruits, vegetables, and temperature-sensitive pharmaceuticals. It boasts a compressive strength of ≥160kPa and bending strength of ≥0.3MPa, ensuring structural stability even in high-traffic industrial environments.
In terms of safety and sustainability, Insulated Cold Storage Panel No.3 meets B2 fire resistance standards, self-extinguishing within 3–5 seconds, and complies with GB 8624 and EU EN 13501-1 regulations. The closed-cell foam structure has a water absorption rate of <0.3kg/m³, preventing moisture ingress and mold growth, while the panel is formaldehyde-free and 100% recyclable, aligning with global eco-friendly initiatives.
Founded in 2003, Changzhou Yijing Refrigeration Equipment Factory operates a 30,000㎡ production facility with 12 advanced PU foaming lines, achieving an annual production capacity of 600,000 square meters of cold storage panels. The company has over 20 years of experience in the refrigeration industry, exporting products to more than 20 countries across Europe, Southeast Asia, and the Middle East. It holds ISO 9001, ISO 14001, and CE certifications, ensuring strict quality control from raw material procurement to finished product delivery.
The global cold storage sandwich panels market is projected to reach USD 4.23 billion by 2035, growing at a CAGR of 6.5%, driven by the expanding cold chain infrastructure and increasing demand for temperature-controlled storage in food and pharmaceutical sectors. With the launch of Insulated Cold Storage Panel No.3, Changzhou Yijing Refrigeration aims to strengthen its market position by providing cost-effective, high-performance solutions that address the evolving needs of the cold chain industry.
Insulated Cold Storage Panel No.3 is now available for global distribution, with OEM/ODM customization options for size, thickness, facing material, and color. The company offers a minimum order quantity of 50㎡, sample delivery within 3–5 days, and a production lead time of 15–20 days after deposit.
