Unlike traditional PUR, Polyisocyanurate (PIR) panels manufactured in advanced Chinese factories utilize a specialized isocyanurate ring structure. This chemical configuration provides superior Class B1 fire resistance, essential for meeting stringent global insurance and safety standards.
Our PIR core achieves a thermal conductivity as low as 0.019 - 0.022 W/m·K. For global enterprises, this translates to a 20-30% reduction in energy consumption compared to standard EPS or Mineral Wool alternatives.
Leading factories in Shaanxi utilize double-belt continuous production lines. This ensures uniform density across the entire panel length, eliminating cold spots and structural weaknesses often found in manual or batch-produced panels.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Since our inception in 1996, we have integrated high-quality product manufacturing with one-stop project solutions. Our expertise spans across fruit and vegetable refrigeration, the food processing industry, large-scale logistics, and medical cold storage.
With over 20 years of experience, we provide a holistic approach to thermal management, ensuring that every PIR sandwich panel meets the rigorous demands of the modern cold storage environment.
Our factory operates 4 standardized workshops equipped with advanced production lines. We specialize in PIR/PU sandwich panels, cold storage doors, and comprehensive refrigeration components.
International buyers are moving away from purely price-based selection toward Lifecycle Cost Analysis (LCA). Chinese PIR factories now offer FM-approved panels that lower insurance premiums, making them a strategic choice for Fortune 500 logistics firms.
The industry is transitioning to Pentane-blown foam technology, which has Zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). Shaanxi YuanShengHeTong is at the forefront of this eco-friendly shift.
Modern PIR panels are designed with "Cam-lock" and "Z-Lock" mechanisms for rapid assembly. This reduces on-site labor by 40%, a critical factor for rapid-growth markets in Southeast Asia and Africa.
PIR panels provide the ultra-stable temperature control required for GSP/GMP certified pharmaceutical storage, preventing temperature fluctuations that could compromise vaccine integrity.
Our seamless PIR sandwich panels are ideal for semiconductor and electronics manufacturing, offering non-gassing properties and easy-to-sanitize surfaces.
For cross-docking facilities, the structural strength of PIR panels allows for taller wall heights without secondary steel support, maximizing internal storage volume.
Our commitment to quality is verified by global certification bodies.
