In an era defined by carbon neutrality targets and the rapid expansion of global cold chains, Polyurethane (PUR) and Polyisocyanurate (PIR) Sandwich Panels have emerged as the gold standard for high-performance building envelopes. As a premier OEM Sandwich Panel Polyurethanes Factory, we recognize that modern infrastructure demands more than just insulation; it requires "thermal intelligence."
Global industrial trends are shifting toward modularity and energy efficiency. From massive logistics hubs in the Middle East to pharmaceutical cleanrooms in Europe, the integration of PUR/PIR technology ensures minimal thermal bridging, superior fire resistance (Class B1), and a structural integrity that withstands the test of time and climate extremes.
By controlling everything from raw material sourcing to final panel assembly, our Shaanxi and Lanzhou factories mitigate market volatility and ensure consistent lead times.
Our 60,000 sqm production site utilizes advanced automatic split-joint production lines, ensuring every PUR/PIR core is uniform in density and bond strength.
With a 10-person dedicated QC team and CE certification, we bridge the gap between "Made in China" and "Global Quality Standards."
Proximity to key transport hubs allows us to export high-volume orders with optimized shipping costs and real-time tracking for global clients.
In high-ambient regions like Southeast Asia or Africa, our high-density PUR panels reduce energy consumption for cold storage by up to 40%, preventing "thermal leakage" in harsh sun.
For medical and vaccine storage, we provide seamless wall panels that meet strict hygiene standards, facilitating easy sterilization and stable -80°C environments.
In rural development projects, our cam-lock sandwich panels allow for rapid deployment of modular fruit and vegetable storage, reducing post-harvest losses significantly.
Founded on a legacy of excellence since 1996, Shaanxi YuanShengHeTong Refrigeration Co., Ltd. has evolved into a leading professional factory focusing on insulation panels and refrigeration equipment. We provide a comprehensive "one-stop project solution," integrating design, manufacture, and international trade.
With over 20 years of experience, we specialize in the refrigeration of fruits, vegetables, and the food industry, alongside serving large supermarkets, hotels, and logistics giants. Our 60,000 square meter site and 180 skilled workers guarantee efficiency and peak performance.
The next decade of sandwich panel manufacturing is driven by three pillars: Sustainability, Digitalization, and Performance.
Developing low-GWP (Global Warming Potential) blowing agents to meet future environmental regulations in the US and EU.
Integrating IoT sensors within the panel core to monitor thermal performance and structural integrity in real-time for smart warehouses.
Combining Vacuum Insulation Panels (VIP) with PUR to achieve R-values twice that of traditional panels with half the thickness.
Entering international markets requires deep knowledge of local building codes. We ensure our panels meet CE Certification, ASTM fire tests, and ISO 9001 standards.
Beyond logistics, we provide remote installation guidance and on-site engineering support for major infrastructure projects, ensuring that our "China-made" panels perform perfectly in their destination environment, regardless of local humidity, seismic activity, or wind load requirements.
PIR (Polyisocyanurate) is an evolved version of PUR. It offers significantly better fire resistance (Class B1) and higher thermal stability compared to standard PUR, making it ideal for high-risk industrial environments.
Yes. As an OEM factory, we offer thicknesses ranging from 50mm to 200mm to accommodate temperatures from standard ambient storage down to -80°C blast freezing.
Cam-lock panels feature integrated eccentric locking systems that allow panels to be joined tightly without external fasteners, significantly reducing onsite labor and ensuring air-tight seals.
Absolutely. We provide one-stop project solutions including compressors, condensers, air coolers, and the sandwich panels themselves, ensuring full system compatibility.
With proper maintenance, our PUR/PIR panels maintain their thermal efficiency and structural integrity for over 20-30 years in industrial environments.
Every batch undergoes rigorous QC testing for density, bond strength, and fire resistance. We provide detailed lab reports and CE certification documentation with every shipment.
