In the modern industrial landscape, the term "Composite Sandwich" refers to much more than a structural component; it is the cornerstone of thermal efficiency, structural integrity, and sustainable building practices. As a premier OEM Composite Sandwich Factory & Exporter, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has spent over two decades refining the alchemy of polyurethane (PU) and polyisocyanurate (PIR) cores bonded with diverse facings to meet the rigorous demands of the global cold chain, pharmaceutical cleanrooms, and architectural sectors.
The "Information Gain" we provide lies in our integrated approach. While many suppliers offer panels, we deliver a holistic thermal envelope. This includes the thermodynamic synergy between our FNV series condensers and the R-value stability of our PIR cam-lock panels. By controlling the entire ecosystem—from core chemistry to the precision engineering of cold storage doors—we ensure that "zero thermal bridging" is not just a marketing claim, but a measurable performance metric.
Utilizing high-density PIR cores (40-45kg/m³) that offer superior fire resistance (Class B1/B2) and structural load-bearing capacity.
Achieving thermal conductivity as low as 0.019 W/(m·K), reducing HVAC energy consumption by up to 35% in large-scale logistics.
Customized dimensions, facings (SS304, Color Steel, GRP), and cam-lock configurations tailored to specific regional installation standards.
Established in 1996, Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Beyond mere manufacture, we provide comprehensive project design, construction, installation, and dedicated after-sales service.
We integrate high-quality products, one-stop project solutions, and international trade expertise to serve sectors including fruit/vegetable cold chains, large supermarkets, hospitality, medical logistics, and pharmaceutical storage.
Years Experience
Sqm Factory
Expert Staff
Founder started in refrigeration marketing and installation services.
First factory in Shaanxi completed; produced initial cam-lock sandwich panels.
LanZhou factory completed, covering the expansive North-West China market.
Shaanxi factory relocated to a 120-acre site with 8 advanced workshops.
Implemented the first automatic split-joint production line for insulation panels.
Second advanced automatic production line commissioned, doubling productivity.
Evolution into an Eco-Friendly Factory, prioritizing sustainable materials.
Our commitment to Industry 4.0 is visible in our 60,000 square meter production site. By utilizing AI-driven precision in our 4 standardized workshops, we minimize material waste and maximize the structural consistency of every PIR and PU panel. Our automatic production lines ensure that the foaming density is uniform across the entire 12-meter panel length, a critical factor for large-scale industrial cold storage.
Supply Chain Resilience: In an era of global uncertainty, our factory serves as a stable hub. We maintain strategic reserves of high-grade steel and chemical precursors, allowing us to maintain lead times even during market volatility. As a leading exporter, we provide full transparency in logistics, ensuring that our products reach sites in SE Asia, the Middle East, and beyond in pristine condition.
Technical Roadmap: Looking toward 2030, our R&D is focused on Ultra-Low GWP (Global Warming Potential) blowing agents and vacuum-insulated core composites. We are also developing "Smart Panels" with embedded sensors to monitor real-time thermal leakage, providing facilities managers with actionable data to prevent food spoilage or pharmaceutical loss.
From pre-cooling at the farm gate to regional distribution centers, our integrated systems ensure the "first mile" and "last mile" are thermally secure.
Cleanroom-certified sandwich panels with antimicrobial coatings, meeting stringent FDA and EMA regulatory requirements for sterile environments.
High-span structural panels that reduce the need for internal steel framing, maximizing internal storage volume and lowering construction costs.
We understand that a "one size fits all" approach doesn't work in international construction. Our engineering team provides localized support, ensuring all OEM Composite Sandwich products meet regional building codes such as:
A: While both offer excellent insulation, PIR (Polyisocyanurate) features a modified molecular structure that significantly enhances fire resistance. PIR panels can achieve a B1 fire rating, charred at the surface to prevent flame spread, whereas standard PU is more flammable. PIR also maintains better dimensional stability across extreme temperature gradients.
A: The Cam-Lock system provides a high-tension mechanical connection between panels. When combined with our precision-engineered gaskets, it creates an airtight seal that eliminates "thermal leaks" at the joints. This is crucial for ultra-low temperature environments (-40°C) where even minor air infiltration can lead to ice buildup and energy loss.
A: Absolutely. For high-humidity tropical environments, we utilize 304/316 stainless steel facings and anti-corrosive coatings. For high-wind load areas, we increase the core density and the gauge of the external skin to ensure structural resilience. Our OEM services cover core thickness from 50mm to 200mm.
A: With proper installation and maintenance, our panels have a service life exceeding 25 years. The closed-cell structure of our foam (over 95% closed-cell content) prevents water absorption, ensuring the R-value remains constant throughout the product's lifecycle.
