In the rapidly evolving landscape of global logistics and temperature-controlled storage, High-Quality Sandwich PU (Polyurethane) and PIR (Polyisocyanurate) Panels have emerged as the gold standard for thermal integrity. At Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd., we combine over 27 years of engineering heritage with cutting-edge manufacturing to provide more than just building materials—we provide high-performance envelopes for the world's most critical assets.
Understanding the difference between PUR (Polyurethane) and PIR (Polyisocyanurate) is crucial for procurement officers and engineers. While both offer exceptional thermal conductivity (λ values as low as 0.019 - 0.022 W/m·K), PIR panels are engineered with a higher isocyanate index. This chemical structural difference grants PIR superior fire resistance properties, often achieving B1 fire ratings, making them the preferred choice for large-scale industrial warehouses where safety compliance and insurance premiums are a priority.
From raw chemical formulation to precision metal roll-forming, our 8 standardized workshops control every variable. This reduces lead times by 30% compared to decentralized manufacturers.
Operating a 60,000 sqm facility allows us to source premium steel and chemical components at scale, passing significant cost savings directly to the global buyer.
Our two advanced automatic production lines utilize Italian-tech continuous foaming processes, ensuring consistent density and zero-void insulation across every panel.
As a leading China PIR/PUR manufacturer, we leverage the robust industrial ecosystem of Shaanxi. Our location serves as a strategic hub for the "One Belt One Road" initiative, allowing for efficient rail and sea logistics to Europe, Southeast Asia, and the Middle East. For global enterprises, this means a reliable "just-in-time" supply chain for massive cold storage projects.
Modern procurement is no longer just about price; it’s about Information Gain and risk mitigation. Shaanxi YuanShengHeTong understands that a cold room in the humid tropics of Indonesia requires different specifications than a logistics hub in the freezing winters of Kazakhstan.
Our sandwich panels are deployed across diverse sectors, including:
• Pharma Logistics: Maintaining ultra-stable temperatures for vaccine storage.
• Food Processing: PIR panels for high-hygiene cleanroom environments.
• Large Supermarkets: Aesthetic exterior wall panels that combine insulation with architectural appeal.
• Data Centers: Managing heat loads with thermal-bridge-free panel joints.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Besides product manufacture, we also provide services like project design, construction, installation, as well as after-sales service.
We integrate "high quality products, one-stop project solution, engineering advanced services, and international trade" to provide customers with excellent products and satisfied services. Our involved professional fields include refrigeration of fruits, vegetables, food industry; also refrigeration of large supermarkets, restaurants, hotels, medical and logistics companies etc.
The move toward "Zero-on-site waste." Our panels are precision-cut to project specs, allowing for 40% faster site assembly.
Integrating IoT sensors within the sandwich panel core to monitor thermal performance and moisture ingress in real-time.
Switching to low-GWP (Global Warming Potential) blowing agents to meet the rising demand for green building certifications like LEED.
