In the modern commercial landscape, energy efficiency, long-term environmental sustainability, and regulatory compliance have transitioned from optional metrics to core operational directives. For multinational corporations, agricultural logistics firms, cold storage developers, and pharmaceutical distribution networks, the selection of wall and ceiling cladding systems is crucial. High-performance building insulation sandwich panels, particularly those optimized for thermal barrier integrity and carrying CE certification, form the structural backbone of these climate-controlled facilities.
The global enterprise demand for high-caliber polyurethane (PU/PUR) and polyisocyanurate (PIR) core sandwich panels is driven by the necessity to maintain tight thermal tolerances, prevent thermal bridging, and satisfy strict building codes. As modern facility managers seek to optimize lifecycle costs (LCC) and achieve high LEED rating scores, they rely heavily on proven manufacturing partners that bridge the gap between custom modular engineering and scalable supply capabilities. Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. represents the peak of this standard, supplying robust cold storage panel solutions designed to perform under demanding environmental dynamics.
Manufactured in full compliance with EN 14509 standards, ensuring optimal mechanical strength, fire safety performance, and structural stability.
Industry-leading thermal performance with low thermal conductivity (λ ≤ 0.020 W/m·K for PIR), translating to direct energy savings.
Engineered with high-precision cam-lock joints that lock panels seamlessly, cutting onsite assembly labor and overall execution timelines.
Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is a leading professional manufacturer and enterprise specializing in insulation panels, high-performance cold room doors, and integrated refrigeration systems. Our operational philosophy is anchored on providing clients with a seamless, comprehensive one-stop project solution. Beyond manufacturing high-end thermal isolation materials, we excel in offering custom engineering design, detailed structural consulting, construction supervision, precise installation, and responsive global after-sales support.
By blending top-tier manufacturing processes, international trade capabilities, and modern engineering practices, we deliver tailor-made systems for agriculture, food processing, logistics distribution, retail supermarkets, cleanrooms, and biological pharmaceutical hubs. Our involvement spans complex high-load environments that demand high thermal reliability, such as multi-temperature zones, blast freezing tunnels, controlled-atmosphere packaging cleanrooms, and heavy-duty cold storage structures.
Our centralized manufacturing facility represents the transition to "China Factory 4.0"—an industrial framework prioritizing process control, high automation, environmental safety, and lean material flow. Operating from a 60,000-square-meter site, the production facility houses four standardized, climate-monitored workshops equipped with continuous double-belt laminating machines and high-precision sheet metal stamping equipment.
With an experienced workforce of over 180 technicians and a dedicated QC squad of 10 QA engineers, quality checks are integrated at every step—from raw steel coil inspection and polyurethane foam chemistry balancing to the profiling phase, cam-lock insertion, and protective film wrapping. By adopting automated continuous PU/PIR foaming production lines, we minimize human error and ensure density uniformity across every batch. Our high efficiency ensures consistent production capacity, shielding our global clients from lead-time volatility and shipping bottlenecks.
Our commitment to sustainable production is reflected in our modern raw material handling. We utilize eco-friendly pentane-blown foaming systems, yielding zero ozone depletion potential (ODP) and negligible global warming potential (GWP), aligning with global green building mandates.
The core efficiency of a cold chain system is determined by the physical characteristics of its thermal envelope. The thermal transmission coefficient (U-value) is determined by the core density, cell structure, and metal facing design. Polyurethane (PUR) and Polyisocyanurate (PIR) cores represent the peak of modern polymer foam insulation.
Thermodynamic Performance: PUR foam consists of closed cells filled with high-efficiency insulating gas. PIR foam, synthesized via isocyanate trimerization, forms a robust ring structure that offers high thermal resistance and fire safety performance. This structural configuration yields a thermal conductivity (λ) of 0.020 W/m·K to 0.024 W/m·K, far lower than typical rockwool or EPS equivalents.
Mechanical Integrity and Lock Mechanics: For modular cold storage facilities, structural stability depends on connection integrity. Shaanxi YuanShengHeTong's Cam-Lock system features high-strength composite locks cast directly into the core foam during manufacture. These interlocking mechanisms slide together securely, pulling the tongue-and-groove joint tight. When sealed with high-elasticity gaskets, this design eliminates thermal bridging and moisture ingress, preventing frost formation and subsequent energy loss.

Different commercial industries require distinct temperature controls. Shaanxi YuanShengHeTong develops custom solutions tailored to specific commercial realities:
Our founder started the business from refrigeration equipment marketing and installation, laying the groundwork for engineering expertise.
With our first factory completed in Shaanxi, we produced our first cam-lock sandwich panels under strict quality controls.
The second factory in LanZhou completed, our business started to cover the whole north-west market in China.
Follow with larger business and international business, the Shaanxi factory relocated to a larger fields, now we possess with 120 acers area with 8 advanced workshops.
With more advanced technology in insulation panel industry, we input our first automatic split-joint production line. Here the new chapter begins.
Our second advanced automatic production line put on stream, we reach to a higher productivity and efficiency with better quality.
With the responsibility of sustainability, we are now moving into an eco-friendly factory, introducing green pentane-blown options.
Securing project approvals requires verified product compliance. Our products undergo third-party structural and environmental assessments, maintaining conformity across our major target markets.
CE Certification & Standard EN 14509: This standard defines the requirements for factory-made self-supporting double-skin metal-faced insulating sandwich panels. Achieving this certification guarantees that our panels resist shear forces, wind-load bending, thermal expansion stresses, and maintain sound-barrier properties.
Onsite Support and Complete Solutions: Our engineering services bridge standard product manufacturing and onsite realization. We provide detailed CAD layouts, load calculations for support structures, joint detailing diagrams, and dispatch experienced engineers to coordinate structural installation on site.
PUR (Polyurethane) and PIR (Polyisocyanurate) are similar polymer foams, but PIR uses a different isocyanate ratio that forms cross-linked chemical rings. This structure makes PIR more resistant to high temperatures, improves fire performance, and yields a lower thermal conductivity rating.
CE Certification verifies that the building panels meet European Union safety, health, and environmental standards (EN 14509). This ensures the structural performance, fire retardancy, and durability of the panels meet compliance standards for commercial construction projects worldwide.
The cam-lock mechanism features hook-and-pin components embedded into the foam core. During installation, these components are tensioned together with an Allen key to pull the panels tight, sealing the joints to prevent thermal leakage and moisture buildup.
Yes. We supply steel facings with custom anti-corrosion properties, including PVDF-coated steel, pre-painted galvanized iron (PPGI), stainless steel (SUS304 or SUS316), and PVC-laminated coatings for high-corrosion or sanitization-heavy environments.
Through our 60,000-square-meter facility and long-term partnerships with raw material chemical suppliers, we maintain steady stock levels. Our automated continuous foaming lines ensure high production rates and stable pricing structures for long-term projects.
We provide complete layout blueprints, structural connection details, and equipment matching proposals. Our team coordinates design parameters for sandwich panels, condensing units, cold storage doors, and evaporator arrays to ensure system compatibility.
