In the modern era of sustainable architecture and high-precision cold chain logistics, CE Certified Sandwich PIR (Polyisocyanurate) Panels have emerged as the gold standard for thermal insulation. Unlike traditional PUR or EPS materials, PIR offers a superior chemical structure that provides exceptional fire resistance (up to B1 grade) and thermal conductivity as low as 0.020 W/mยทK.
As a leading manufacturer, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has spent over two decades refining the structural integrity and thermal efficiency of these panels. Our CE certification is not just a badge; it is a testament to our adherence to strict European safety, health, and environmental protection requirements, ensuring that our products meet the rigorous demands of the global market.
When selecting a manufacturer, most buyers focus on price. However, our technical whitepaper highlights "Thermal Aging Stability." Our PIR panels maintain 95% of their R-value even after 25 years of service, a critical factor for long-term ROI in cold storage investments.
The secret lies in the isocyanurate ring. By increasing the ratio of MDI to Polyol and utilizing advanced blowing agents, we create a closed-cell structure that acts as a near-perfect barrier against heat transfer and moisture migration.
Our panels are tested under EN 13165 standards, ensuring that our partners in Europe, Southeast Asia, and the Americas can import with zero regulatory friction.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Since 1996, we have integrated high-quality products, one-stop project solutions, and engineering excellence.
Our factory spans 60,000 square meters with 4 standardized workshops and advanced production lines specializing in PIR and PU sandwich panels, cold storage doors, and compressor units.
Adapting PIR technology to diverse climatic and industrial needs.
In regions like Northern Europe or North America, our 200mm PIR panels are used for deep-freeze facilities (-40ยฐC), where minimizing thermal bridging is non-negotiable for energy savings.
For clients in Southeast Asia and the Middle East, our panels feature high-reflectivity steel skins to combat intense solar radiation, significantly reducing HVAC loads.
The seamless joint design and anti-bacterial coatings of our PIR panels make them ideal for FDA-compliant pharmaceutical manufacturing and storage.
With the rise of AI, data centers require high fire-safety ratings. Our B1 PIR panels provide the necessary thermal barrier and fire containment required by modern tech infrastructure.
As a leading Chinese manufacturer, our competitive advantage extends beyond low costs. It is built on Supply Chain Integration. We source premium steel and chemical raw materials from top-tier domestic clusters, ensuring stable pricing and lead times even during global market volatility.
Development of PIR panels with embedded IoT sensors to monitor real-time thermal performance and structural integrity, predicting maintenance needs before they arise.
Transitioning from petroleum-based chemicals to bio-polyols derived from agricultural waste, reducing the carbon footprint of our manufacturing process by 30% by 2030.
Engineering next-gen PIR with Opacified Aerogel integration to achieve the same R-value with 40% less thickness, maximizing usable interior space in cold storage.
Quality and compliance you can trust on a global scale.
