Polyisocyanurate (PIR) core technology offers superior fire resistance compared to standard PUR. Our panels are engineered to char rather than melt, significantly slowing flame spread and smoke production, meeting international safety protocols for large-scale industrial facilities.
With a thermal conductivity of approximately 0.019 - 0.022 W/m·K, PIR panels provide the highest R-value per inch of any commercial insulation. This translates to 30% higher energy savings compared to EPS or Rockwool solutions in cold storage environments.
The high-density foam (typically 40-42 kg/m³) provides immense compressive strength. When bonded with galvanized or stainless steel skins, these panels act as high-load-bearing structural elements for walls and roofs.
In the global refrigeration and construction sectors, the "China PIR Sandwich Panel Specification" has become a benchmark for balancing cost-efficiency with high-end performance. As energy costs rise, the demand for "Information Gain" in building materials has shifted from mere thickness to chemical composition and manufacturing precision. Shaanxi YuanShengHeTong, with its 20-year legacy, integrates advanced Pentane Foaming Technology, ensuring zero ODP (Ozone Depletion Potential) and low GWP (Global Warming Potential), aligning with modern ESG (Environmental, Social, and Governance) requirements for multinational corporations.
By managing everything from the chemical formulation of the PIR core to the precision cold-rolling of the steel skins, Chinese factories reduce lead times by 40% compared to Western competitors.
Our 60,000 sqm facility utilizes Hennecke (Germany) style continuous production lines, ensuring consistent density and bond strength across every square meter produced.
Strategically located in Shaanxi and Lanzhou, we leverage the "One Belt One Road" infrastructure for seamless rail and sea transport to Central Asia, Europe, and Southeast Asia.
Whether it's Cam-lock systems for portable cold rooms or continuous panels for mega-logistics centers, our engineering team provides localized drawings and CAD support.
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.
Our business in refrigeration fields started in 1996, with more than 20 years experience in refrigeration industry, we are confident in our professionality. And our factory is specializing in refrigeration manufacturing and technology.
The PIR sandwich panel industry is evolving towards "Smart Insulation." This includes the integration of IoT sensors within panels to monitor moisture ingress and thermal bridging in real-time. Furthermore, the shift from PUR to PIR is accelerating as insurance companies demand higher fire ratings for warehouses containing high-value electronic or pharmaceutical goods.
For global procurement managers, the focus has shifted from "Price per Square Meter" to "Total Cost of Ownership (TCO)." High-quality Chinese PIR panels reduce lifelong energy consumption and insurance premiums, providing a superior ROI (Return on Investment).
Precision temperature control (+2°C to +8°C) is critical. Our PIR panels ensure zero thermal fluctuation, protecting life-saving vaccines and biologics.
The non-porous, anti-bacterial coating on our steel skins makes our panels ideal for semiconductor and biotechnology cleanrooms requiring ISO Class 5 air purity.
PIR panels resist the frequent wash-downs and chemical cleaners used in meat and dairy processing facilities while maintaining structural strength.
