The global demand for PU (Polyurethane) and PIR (Polyisocyanurate) sandwich panels has seen a CAGR of 7.4% over the last decade. As urbanization accelerates and the global cold chain logistics market expands to reach an estimated $585 billion by 2028, the role of high-efficiency insulation panel machines has become a cornerstone of industrial growth.
Current trends are shifting toward continuous production technology and "Smart Factories." Manufacturers are now integrating AI-driven quality control to ensure uniform foam density and structural integrity. There is a marked transition from traditional PUR to PIR cores due to stricter fire safety regulations (B1/B2 ratings) in Europe and North America.
Eco-friendly blowing agents like Pentane are replacing HCFCs. OEM manufacturers are prioritizing energy-efficient machinery that reduces waste and carbon footprints during the manufacturing of insulation panels, aligning with global Net-Zero initiatives.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a premier professional factory and enterprise focusing on insulation panels and refrigeration equipment. Beyond product manufacture, we provide comprehensive services including project design, construction, installation, and dedicated after-sales support.
We integrate "high-quality products, one-stop project solutions, advanced engineering services, and international trade" to provide customers with excellent products and satisfied services. Our expertise spans fruit and vegetable refrigeration, the food processing industry, large supermarkets, medical storage, and logistics companies.
Since starting our journey in 1996, we have accumulated over 20 years of experience, establishing ourselves as a trusted OEM PU Sandwich Panel Machine Manufacturer and exporter.
In Southeast Asia, our panels are engineered for high humidity resistance to prevent corrosion in tropical food processing plants. In the Middle East, our PIR panels are favored for their extreme thermal stability under high ambient temperatures. In the European market, we focus on seamless cam-lock systems for modular cold rooms that meet strict hygiene standards.
Phase 1: Integration of automated double-belt laminators for continuous panel production.
Phase 2: Implementation of IoT sensors on production lines for real-time monitoring of foam injection pressure.
Phase 3 (Current): Development of "Zero-Thermal-Bridge" joint designs to eliminate energy leakage in high-end cold storage facilities.
We don't just sell machines; we provide turnkey industrial ecosystems. This includes the integration of Copeland/Bitzer compressor units with our proprietary PUR/PIR panels to create a hermetically sealed environment. This holistic approach ensures that the "Information Gain" for our clients isn't just about the product—it's about the efficiency of the entire refrigeration cycle.
PUR (Polyurethane) is a standard insulation material. PIR (Polyisocyanurate) is a fire-improved version of PUR. PIR has a higher ratio of isocyanate to polyol, which creates stronger molecular bonds that provide better heat resistance and lower flammability, often reaching B1 fire ratings.
The cam-lock system allows for "click-and-connect" assembly. It ensures a high-tension joint between panels, minimizing thermal bridges and air leakage, which is critical for ultra-low temperature medical and food storage.
Yes. As an OEM manufacturer, our automatic production lines can be adjusted to produce panels with thicknesses ranging from 50mm to 200mm and lengths tailored to specific project site requirements.
We have transitioned to using Pentane-based blowing agents, which have zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential), ensuring our products meet international environmental standards.
