Polyurethane (PUR) and Polyisocyanurate (PIR) cores represent the pinnacle of thermal barrier technology. With a lambda value as low as 0.019 W/m·K, our sandwich panels provide 30% more energy efficiency compared to traditional rock wool or EPS alternatives. Our CE certified production line ensures that every panel meets the stringent European Union safety and performance standards.
In the modern industrial landscape, PIR panels offer enhanced fire safety (B1 or B2 grade) due to their thermosetting properties. When exposed to fire, the surface forms a protective carbonized layer, preventing further flame spread—a critical requirement for insurance compliance and operational safety in large-scale logistics hubs.
As a leading CE Certification Sandwich Panel PUR Factory, we navigate the complex landscape of international standards including ISO9001 and CE. This ensures our exporters can provide seamless customs clearance and building permit approvals for projects in Europe, the Middle East, and Southeast Asia.
Our manufacturing ecosystem in Shaanxi leverages automated continuous production lines to minimize human error and maximize structural uniformity.
We don't just sell panels; we engineer environments. From initial project design and heat load calculation to the manufacturing of cold storage doors and condensing units, our factory provides a vertically integrated supply chain that reduces procurement costs by up to 15%.
Our specialized PUR Polyurethane Cam-Lock Sandwich Panels utilize high-precision interlocking systems. This ensures airtight seals, vital for medical refrigeration and vacuum-sensitive food processing environments, preventing thermal bridges and ice formation.
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.
Our R&D is currently focused on next-generation blowing agents with zero Ozone Depletion Potential (ODP) and ultra-low Global Warming Potential (GWP). Transitioning to eco-friendly factory status (2023 milestone) is just the beginning of our carbon-neutral journey.
Future sandwich panels will incorporate embedded IoT sensors to monitor core temperature and moisture levels, providing real-time data to building management systems to prevent structural degradation before it occurs.
We are expanding our "Plug-and-Play" modular cold storage solutions. These units are 100% factory-prefabricated, including the condensing unit and evaporator, allowing for 48-hour onsite assembly.
Our PIR panels meet the strict hygiene requirements for pharmaceutical storage (GDP compliance). The seamless surface finish prevents bacterial growth and resists aggressive cleaning agents.
For large-scale logistics, our PIR/PUR Foam Core Wall Panels provide the structural rigidity needed for high-bay warehouses while maintaining the required thermal gradient for multi-temperature zones.
We provide localized technical support and installation training for our global partners, ensuring that our CE certified products are installed to maximum efficiency standards anywhere in the world.
