Polyisocyanurate (PIR) foam sandwich panels offer exceptional fire resistance compared to standard PUR. Our panels are B1/B2 class certified, ensuring safety in high-density industrial environments.
With a thermal conductivity as low as 0.019 - 0.022 W/mยทk, PIR panels maximize energy savings in cold storage and HVAC applications, reducing operational costs by up to 30%.
Engineered for durability, our OEM panels feature high compressive strength and moisture resistance, making them ideal for large-span industrial roofs and walls.
Established in 1996, Shaanxi YuanShengHeTong Refrigeration Co., Ltd. has evolved from a local installation firm into a global leader in insulation panels and refrigeration equipment. Our integrated approach combines high-quality manufacturing with one-stop project solutions.
Our 60,000 square meter facility houses four standardized workshops equipped with advanced automatic production lines. With over 180 skilled workers and a dedicated 10-person QC team, we ensure every panel and unit meets international standards.
Since 2018, we have invested in automatic split-joint production lines. This reduces human error, ensures uniform foam density, and increases output to meet global demand efficiently.
Located in the heart of China's industrial hub, we have immediate access to high-grade steel and chemical raw materials, allowing us to offer competitive OEM pricing without compromising quality.
Our experience in international trade since the early 2010s means we handle the complexities of global shipping, documentation, and compliance, providing a "factory-to-site" experience.
The transition to pentane-based blowing agents has made PIR panels much more environmentally friendly, with zero Ozone Depletion Potential (ODP). As a responsible factory, we adopted green manufacturing practices in 2023 to support global carbon neutrality goals.
The rise of "Dark Stores" and rapid-deployment vaccine storage requires modular PIR solutions. Our cam-lock and tongue-and-groove designs allow for assembly in days rather than months.
Modern PIR panels are now being integrated with IoT sensors to monitor internal temperature gradients, ensuring the integrity of sensitive pharmaceutical and food products.
Global building codes are tightening. The shift from PUR to PIR is no longer a luxury but a requirement for high-rise cold storage and high-value industrial warehouses.
Controlled atmosphere storage for fruits and vegetables, extending shelf life and reducing waste.
Strict temperature-controlled environments for vaccine and medicine storage (GSP/GMP compliant).
Large-scale distribution centers and automated cold-chain hubs for e-commerce giants.
Thermal management for high-density server rooms, preventing overheating through precision insulation.
