Engineered thermal systems and structural sandwich assemblies designed to maintain rigid temperature differentials under extreme industrial operations.
Established as an authoritative pioneer in temperature-regulated infrastructure and composite thermal panels, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. delivers engineered, end-to-end insulation and refrigeration systems globally. With origins stretching back to 1996, we have established a robust vertically-integrated manufacturing model that blends advanced material science with industrial refrigeration engineering.
Our specialization encompasses structural polyurethane (PU) and polyisocyanurate (PIR) rigid core sandwich panels, cold-room door mechanisms, evaporators, condenser units, and high-capacity refrigeration compressors. Operating out of our specialized 60,000 square meter facility, we design custom systems serving global supermarkets, agricultural processing centers, pharmaceutical clean rooms, and logistic mega-hubs.

Exploring the convergence of insulation performance, aesthetic flexibility, and strict environmental compliance in global composite cladding technologies.
Polyurethane (PU) and Polyisocyanurate (PIR) cores offer exceptional thermal properties, achieving a low thermal conductivity (k-factor) of 0.018 - 0.022 W/m·K. This outperforms mineral wool or expanded polystyrene (EPS), enabling thinner wall profiles without sacrificing thermal performance.
Modern architectural designs demand both high performance and aesthetic appeal. Decorative PU sandwich panels feature outer layers made of pre-painted steel (PPGI), aluminum, or zinc-coated alloys. These layers are embossed with textures like woodgrain, stone, or brick to combine strength with high-end design.
To align with global environmental standards, our manufacturing lines use pentane-blown blowing agents. These formulations are CFC- and HCFC-free, resulting in zero Ozone Depletion Potential (ODP) and a low Global Warming Potential (GWP), which helps projects earn LEED and BREEAM certifications.
B2B procurement professionals, structural engineers, and cold chain managers face complex compliance and technical requirements when sourcing panels. For building facades, public facilities, and food logistics centers, projects must balance thermal, structural, and fire performance.
Our engineering support matches custom specifications to project requirements: thickness adjustments (50mm to 200mm), joint seals (interlocking cam-locks for cleanrooms, tongue-and-groove for claddings), and corrosion-resistant coatings (PVDF or HDP) for coastal and chemical environments.

| Polyisocyanurate (PIR) | 0.018 - 0.020 | 40 - 45 | Class B-s1, d0 (Self-Extinguishing) | < 1.5% | High Compatibility (Factory Molded) |
| Expanded Polystyrene (EPS) | 0.033 - 0.038 | 15 - 25 | Class E / F | < 4.0% | Low Compatibility (Requires Insertion) |
| Mineral Rockwool | 0.038 - 0.044 | 100 - 140 | Class A1 (Non-Combustible) | High (> 10% if unsealed) | Not Recommended |
Our Shaanxi manufacturing center integrates digital quality controls and lean production workflows to handle large-scale orders while maintaining consistent product standards. Automated split-joint production lines run high-pressure continuous foaming systems to ensure uniform density distribution and eliminate internal voids.
Operating with local material networks in Western and Northern China, our plants in Shaanxi and Lanzhou manage steel coil preparation, structural panel forming, and cooling processes efficiently. Testing protocols measure flat adhesion strength, compressive yield, dimensional stability under temperature variations, and core closed-cell ratios, ensuring all shipped panels perform reliably in the field.
