The 25mm sandwich panel, often referred to as a "thin-profile high-performance insulator," occupies a critical niche in the global construction and refrigeration market. Unlike thicker panels (50mm-200mm) used for heavy-duty cold storage, the 25mm variant is the gold standard for HVAC ducting, cleanroom partitions, and modular cabin construction. As global energy prices fluctuate, the demand for PIR (Polyisocyanurate) cores with CE certification has surged, offering a superior thermal-to-thickness ratio that traditional fiberglass or rockwool cannot match.
In the EU and North American markets, stringent fire safety regulations and the "Green Building" initiative have pushed manufacturers to innovate. Our 25mm panels are engineered to provide maximum R-value while maintaining a lightweight footprint, facilitating rapid installation and reducing structural load in high-rise industrial complexes.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is not just a manufacturer; we are a comprehensive solution provider. Founded in 1996, our journey spans over two decades of technical evolution. We integrate one-stop project solutions with international trade standards to serve industries ranging from food processing to pharmaceutical logistics.
Our commitment to quality is backed by a 60,000 square meter facility and four standardized workshops. We specialize in the production of PIR and PU sandwich panels, air coolers, and advanced condensing units. Our "engineering advanced services" ensure that every 25mm panel we produce meets the precise thermal requirements of your specific project.
Transitioning from standard PU to high-index PIR cores to achieve B1 fire ratings even at thin 25mm dimensions.
Implementation of the automatic split-joint production line (2018) to ensure 0.1mm tolerance levels for seamless locking.
2023 Roadmap: Introducing low-GWP blowing agents to meet future environmental mandates across the EU and Asia.
Internal partitioning in large-scale refrigerated warehouses where space optimization is paramount.
The 25mm panel's seamless surface provides an anti-bacterial environment essential for medical manufacturing.
