The "Full Form" of PIR stands for Polyisocyanurate. In the global construction and refrigeration industry, PIR Sandwich Panels represent the evolution of the traditional Polyurethane (PUR) system. By increasing the ratio of isocyanurate, the chemical structure creates stronger molecular bonds, resulting in a material that offers superior thermal resistance and exceptional fire performance.
As a leading PIR Sandwich Panel manufacturer and exporter, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. provides CE-certified solutions that integrate high-density PIR foam between two layers of galvanized or stainless steel. This modular "sandwich" structure is the backbone of modern temperature-controlled environments, offering an unmatched strength-to-weight ratio.
Modern enterprises in the EU, Middle East, and Southeast Asia are shifting procurement strategies toward CE-certified PIR panels due to tightening building codes and insurance requirements (such as FM Global). The demand is driven by three core pillars:
Large-scale logistics hubs require PIR panels to minimize HVAC operational costs. Our PIR solutions reduce energy leakage by 35% compared to conventional materials, directly supporting Corporate Social Responsibility (CSR) and ESG goals.
Insurance premiums for industrial warehouses are significantly lower when using PIR over PUR. The char-forming property of polyisocyanurate acts as a barrier to flame spread, meeting stringent international safety audits.
For global exporters, the "Cam-Lock" or "Tongue-and-Groove" joints allow for rapid installation. This reduces "Time-to-Market" for pharmaceutical cold chains and food processing plants.
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 manufacturing with one-stop project solutions, including project design, construction, installation, and after-sales support.
With an existing production site of 60,000 square meters and 4 standardized workshops, our 180+ workers and dedicated QC team ensure that every panel leaving our facility meets the highest global standards. Our specialization in PIR (Polyisocyanurate) and PU (Polyurethane) sandwich panels has made us a preferred partner for large supermarkets, hotels, medical centers, and logistics companies worldwide.
Founder started business in refrigeration equipment marketing and installation.
First factory completed in Shaanxi, producing the first generation of cam-lock sandwich panels.
Relocated to a 120-acre facility with 8 advanced workshops to handle growing international business.
Implemented the first automatic split-joint production line for precision engineering.
Second advanced automatic line commissioned, reaching peak production efficiency.
Transitioned into an eco-friendly factory with a focus on sustainable manufacturing processes.
The PIR sandwich panel industry is evolving towards "Smart Thermal Envelopes." Our R&D focuses on the following technical trajectories:
Pushing the thermal conductivity (位) below 0.018 W/m路K through nanopore insulation integration within the PIR matrix.
Full transition to Pentane-driven blowing agents with Zero Ozone Depletion Potential (ODP) and Global Warming Potential (GWP).
Developing recyclable PIR cores and using recycled steel substrates to achieve a 100% closed-loop product lifecycle by 2030.
Providing digital twins for our panels to allow architects to simulate thermal performance in 3D Building Information Modeling environments.
Our products are rigorously tested to meet EN 14509 standards, ensuring structural integrity and thermal consistency for international export.
Custom PIR panel configurations for -40掳C blast freezers and +15掳C distribution zones. Our systems prevent thermal bridging through specialized joint designs, ensuring the integrity of perishable goods.
High-density PIR panels with anti-bacterial coatings and flush-mount finishes, meeting GMP standards for vaccine and medicine storage.
Corrosion-resistant surface materials (SS304/SS316) combined with PIR cores to withstand frequent chemical cleaning and high-humidity environments.
Providing the optimal R-value for vertical farms and greenhouses, reducing the carbon footprint of indoor cultivation.
The full form is Polyisocyanurate. It is a thermoset plastic produced as a foam and used as rigid thermal insulation. It is chemically similar to polyurethane (PUR) but with a higher percentage of isocyanurate, which significantly improves its fire resistance and thermal stability.
CE Certification ensures the product complies with EU safety, health, and environmental protection requirements. For PIR panels, it guarantees that the declared thermal conductivity (U-value) and fire classification (Reaction to Fire) have been verified by third-party laboratories.
PIR has a much lower thermal conductivity (approx. 0.020 W/m路K) compared to Rockwool (approx. 0.035-0.040 W/m路K). This means you can achieve the same insulation performance with a much thinner PIR panel, saving space and reducing structural weight.
Yes. As an exporter, we offer comprehensive installation drawings, remote technical supervision, and on-site support for large-scale infrastructure projects across Africa, Central Asia, and Southeast Asia.
We manufacture panels ranging from 50mm to 250mm. For standard cold storage (-18掳C), 120mm to 150mm PIR panels are recommended, while deep-freeze applications typically use 200mm+ thicknesses.
