In the modern era of global cold chain logistics and sustainable construction, the role of Polyurethane (PU) Sandwich Panels has transitioned from a basic building material to a critical component of energy efficiency and carbon neutrality. As a leading CE Certification Sandwich PU Panel Factory and Exporter, Shaanxi YuanShengHeTong is at the forefront of this thermal revolution.
PU panels offer the lowest thermal conductivity (λ) among common insulation materials, ensuring massive energy savings for cold storage operators.
Our panels meet rigorous European standards (EN 14509), guaranteeing structural integrity, fire resistance (B1/B2 grades), and environmental safety.
With localized support and a robust supply chain, we deliver custom-engineered panels to Southeast Asia, Europe, and the Middle East.
Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is a premier professional factory specializing in high-density insulation panels and integrated refrigeration systems. Since 1996, we have evolved from a regional equipment marketer into a global industry leader.
Our 60,000-square-meter facility houses 4 standardized workshops equipped with advanced automatic split-joint production lines. With over 180 skilled workers and a dedicated 10-person QC team, we ensure every panel and condensing unit exceeds international benchmarks.
"We integrate high-quality products, one-stop project solutions, and international trade to empower the global food and medical supply chains."
Ideal for standard cold storage (-30°C to +10°C). Our PUR panels utilize high-pressure foaming technology to ensure a uniform density of 40-42 kg/m³, providing superior structural rigidity and bonding.
The premium choice for fire-sensitive environments. PIR features an increased isocyanurate index, creating a stable cyclic structure that resists combustion and maintains thermal performance even at extreme temperatures.
Our proprietary Cam-Lock system ensures air-tight seals, reducing installation time by 40% and preventing thermal bridging—a critical factor in high-humidity tropical climates.
In Southeast Asia and the Middle East, our panels withstand 40°C+ ambient temperatures, maintaining precise -18°C for frozen food exports. The CE-certified UV-resistant coating prevents panel degradation in high-intensity sunlight.
Precision is vital for vaccines. Our seamless PUR panels ensure zero-leakage environments, compatible with high-end sensors and medical-grade air coolers to maintain GSP compliance.
Modern "Energy-Plus" buildings utilize our PIR core panels for architectural facades, combining aesthetic versatility with extreme thermal insulation for LEED-certified projects.
China’s role as the "World's Factory" is nowhere more evident than in the PU panel industry. Shaanxi YuanShengHeTong leverages this ecosystem to offer Information Gain to our clients through:
Trust is built on verification. Our factory maintains rigorous ISO 9001 and CE certifications to ensure global compliance.
Integrating IoT sensors within the PU core to monitor insulation efficiency and moisture ingress in real-time.
Transitioning from petroleum-based chemicals to renewable sources, reducing the carbon footprint of production by 30%.
Hybrid panels combining PU with VIP (Vacuum Insulation Panels) to achieve R-values previously impossible in standard widths.
