Addressing global food security by minimizing post-harvest losses through high-performance thermal insulation. Our PUR/PIR panels ensure a stable -40°C to +10°C environment, critical for the global logistics of perishable goods.
With rising energy costs, our CE-certified panels offer superior R-values, reducing HVAC energy consumption by up to 30%. We support enterprises in meeting their Carbon Neutrality goals through advanced materials.
Providing sterile and temperature-precise environments for the medical industry. Our panels meet international hygiene standards, ensuring the safe storage of vaccines and life-saving biologicals.
As a leading CE Certification PUR PIR Sandwich Panels Exporter, understanding the material science is paramount. Both Polyurethane (PUR) and Polyisocyanurate (PIR) are high-efficiency insulators, but they cater to different engineering requirements.
Thermal conductivity as low as 0.019 - 0.022 W/(m·K), making it the most efficient mass-produced insulation material available.
PIR panels achieve Class B1 fire ratings. Under high heat, they form a carbonized protective layer that prevents further flame spread.
Our panels feature high compressive strength (>150 kPa), allowing for the construction of high-bay cold storage warehouses exceeding 30 meters.
Closed-cell rates of over 95% ensure water absorption is negligible, maintaining insulation properties for over 25 years.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Besides product manufacture, we also provide services like project design, construction, installation, as well as after-sales service.
We integrate "high quality products, one-stop project solution, engineering advanced services, and international trade" to provide customers with excellent products and satisfied services. Our involved professional fields include refrigeration of fruits, vegetables, food industry; also refrigeration of large supermarkets, restaurants, hotels, medical and logistics companies etc.
With about 180 workers and 10 QC team, the quality and efficiency are guaranteed. Now, the factory has an existing production site of 60,000 square meters, 4 standardized workshops, and advanced production lines.
Our products undergo rigorous testing to meet CE Certification requirements, ensuring safe entry into European and North American markets.
We provide localized installation guides and 24/7 technical support, adapting our engineering solutions to local climate conditions and building codes.
Strategically located in Shaanxi, we leverage major logistics hubs to ensure timely delivery to the Belt and Road regions and beyond.
Our R&D team is currently focusing on Next-Generation "Smart Panels" integrated with IoT sensors to monitor thermal leakage in real-time. We are also transitioning to zero-ODP (Ozone Depletion Potential) blowing agents to protect our environment.
Developing structural panels designed specifically for AI-driven automated retrieval systems (AS/RS).
Optimizing PIR core density to achieve "passive house" standards for refrigerated warehouses.
Switching to bio-based polyols to reduce the carbon footprint of sandwich panel manufacturing.
PUR (Polyurethane) is excellent for standard cold storage. PIR (Polyisocyanurate) is an enhanced version with superior fire resistance (Class B1) and slightly better thermal stability, often required for large-scale industrial projects.
CE Certification ensures the product meets EU safety, health, and environmental protection requirements. For importers, it guarantees high quality and simplifies customs clearance in many international regions.
Yes. Our panels are designed with smooth surface finishes (PPGI or Stainless Steel) that are easy to sanitize, making them ideal for pharmaceutical and food processing cleanrooms.
Thanks to our high closed-cell foam technology and anti-corrosive steel coatings, our panels typically have a service life exceeding 20-25 years with proper maintenance.
