High-efficiency components for professional refrigeration and insulation.
Why PIR (Polyisocyanurate) is redefining the global cold chain landscape.
Unlike traditional PUR, our PIR core sandwich panels achieve B1-grade fire resistance. The isocyanurate ring structure provides superior carbonization at high temperatures, preventing flame spread in critical facilities.
Our panels offer the lowest thermal conductivity in the mass-market, ensuring that your Energy Efficiency Ratio (EER) remains optimal, reducing operational costs for large-scale cold logistics.
Engineered with double-sided galvanized or stainless steel, our PIR panels serve as both load-bearing and insulation members, capable of withstanding significant wind and seismic loads.
27 Years of Manufacturing Prowess
Founded in 1996, Shaanxi YuanShengHeTong Refrigeration Co., Ltd. has evolved from a local refrigeration service provider into a global powerhouse in insulation panels and refrigeration equipment. We integrate advanced R&D, one-stop project design, and Industry 4.0 manufacturing to serve the fruit, vegetable, pharmaceutical, and logistics industries.
The transition from commodity panels to intelligent insulation systems.
Our founder launched the business focused on refrigeration equipment marketing and installation, building the technical foundation for future manufacturing.
Completed the first Shaanxi factory producing cam-lock sandwich panels. By 2012, we relocated to a 120-acre facility with 8 advanced workshops to meet skyrocketing international demand.
Integration of our first automatic split-joint production lines. Introduction of high-density PIR cores to replace traditional PUR, meeting global fire safety and thermal standards.
Transitioning into an Eco-Friendly factory. R&D focuses on Pentane-blown (CFC-free) foaming agents and AI-integrated cold storage monitoring systems for the global "Green Logistics" initiative.
Ensuring precision and quality through advanced automation.
Vertical-specific integration of PIR sandwich panels.
Ultra-precise temperature maintenance for vaccines and biologics. Our seamless PIR panels eliminate thermal bridges, critical for GXP compliance.
Extending shelf life of perishables. Our FNV and FNH series condensing units paired with PIR panels reduce energy consumption by up to 35%.
Combining aesthetics with insulation. Our PUR/PIR exterior wall panels provide a sleek, modern finish while ensuring LEED and BREEAM certification readiness.
Our commitment to global standards and reliability.
Leveraging scale, speed, and precision in PIR production.
In an era of global supply chain volatility, our Shaanxi facility stands as a bastion of resilience. By integrating raw material sourcing, automated continuous production, and a proprietary logistics network, we offer "Information Gain" to our clients—the certainty of price and delivery.
We manufacture not just the panels, but the condensers, evaporators, and doors, ensuring 100% compatibility and synchronized lead times.
Every PIR batch undergoes a Closed-Cell Content Test and Fire Retardancy verification before shipment to ensure consistency with international ASTM standards.
Located at the heart of the "One Belt One Road" initiative, our factory provides unique logistical advantages for land-bridge rail and sea freight to Central Asia, Europe, and Southeast Asia.
Bridging the gap between Chinese manufacturing and local regulations.
We provide comprehensive documentation support for local building codes, including:
Our PIR panels are designed to meet the FM Global (Factory Mutual) approach to fire safety, ensuring that global enterprises can secure lower insurance premiums for their facilities.
Expert answers to common engineering and procurement questions.
PIR is an improved version of PUR (Polyurethane). By increasing the ratio of Isocyanate, PIR forms a more stable molecular structure (isocyanurate rings) which offers significantly better fire resistance and higher thermal stability than standard PUR.
Due to its high closed-cell count (>95%) and low thermal conductivity (λ=0.019-0.022 W/m·K), PIR panels can reduce cooling energy demand by 20-30% compared to EPS or Rockwool panels of the same thickness.
Yes. Our seamless joint technology and anti-corrosive surface coatings (like PVDF or stainless steel) make our PIR panels ideal for pharmaceutical and food-processing cleanrooms where hygiene is paramount.
When properly installed, our engineering-grade PIR panels have a service life exceeding 25-30 years with minimal degradation in thermal performance.
Complete your refrigeration cycle with factory-direct equipment.
