In the modern era of logistics, the "Cold Chain" is the backbone of global food security and medical safety. As a leading CE Certification Sandwich Panel PIR Manufacturer, Shaanxi YuanShengHeTong Refrigeration Co., Ltd. recognizes that insulation is not just about keeping things cold—it's about thermal precision, energy conservation, and structural longevity. Our PIR (Polyisocyanurate) panels represent the pinnacle of chemical engineering, offering a closed-cell structure that outperforms traditional materials in every metric.
PIR panels feature an incredibly low thermal conductivity (Lambda value), typically around 0.022 W/m·K, ensuring minimal energy loss even in extreme ambient temperatures.
Unlike standard PUR, PIR panels are engineered for higher fire safety standards (B1/B2 rating), charring rather than melting under direct flame exposure.
Our export-grade panels undergo rigorous testing to meet European Union standards, guaranteeing safety, health, and environmental protection compliance.
The global demand for high-end cold storage is shifting from simple warehouses to "Smart Cold Hubs." Whether in the humid tropical regions of Southeast Asia or the arid climates of the Middle East, our PIR sandwich panels are designed to adapt.
In Southeast Asia, moisture resistance and anti-corrosion are paramount. Our panels utilize high-specification galvanized or stainless steel skins to prevent oxidation in high-humidity environments. In European markets, the focus is on the Circular Economy and carbon footprints. Our automatic production lines minimize waste, and the long lifecycle of our PIR cores aligns with Green Building certifications.
Ultra-precise temperature control for vaccines and sensitive biologics, requiring panels with zero thermal bridging.
Hygienic, easy-to-clean surfaces that withstand rigorous chemical sanitization protocols in meat and dairy plants.
Modular PIR solutions for urban distribution centers, supporting the rapid growth of e-commerce grocery services.
Operating from Shaanxi and Lanzhou, Shaanxi YuanShengHeTong Refrigeration leverages China's unmatched manufacturing ecosystem. Our factory doesn't just produce panels; we manage a vertically integrated supply chain that ensures price stability and rapid fulfillment even during global logistics disruptions.
Direct partnerships with top-tier steel and chemical suppliers ensure the highest grade MDI and polyol precursors for our PIR foam.
With our advanced automatic split-joint production lines (introduced in 2018 and expanded in 2020), we have slashed lead times by 40% while increasing dimensional accuracy to the millimeter.
Foundation: Focus on refrigeration marketing and installation services.
Expansion: Shaanxi factory relocated to a 120-acre facility with 8 advanced workshops.
Innovation: Second automatic line operational, reaching peak productivity.
Sustainability: Transitioning to a net-zero, eco-friendly manufacturing model.
Our future roadmap includes the integration of Phase Change Materials (PCM) within the PIR core to further stabilize temperatures during power outages, and the implementation of IoT sensors directly into panels to monitor structural health and insulation performance in real-time.
A: While both are polyurethane-based, PIR uses a higher ratio of isocyanurate, resulting in a stronger chemical bond that significantly improves fire resistance and thermal stability.
A: It ensures that the product meets EU safety standards, simplifies customs clearance, and provides peace of mind regarding the structural and fire-safety integrity of the building materials.
A: Yes, our automatic production lines can adjust panel lengths and thicknesses (from 50mm to 200mm+) to meet specific R-value requirements for any industrial design.
A: When properly installed and maintained, our panels are designed to last over 25 years without significant loss in thermal performance.
