Engineered thermal systems and components integrated seamlessly with our PU wall insulation panels.
Modern commercial warehousing, agricultural cold-chain distribution, and chemical cleanrooms demand uncompromising performance in thermal boundaries. PU (Polyurethane) and PIR (Polyisocyanurate) sandwich panels represent the pinnacle of thermal efficiency, combining low thermal conductivity with strong structural rigidity. As leading global manufacturers, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. addresses the evolving needs of structural engineering, fire dynamics, and energy economics.
Polyurethane chemistry utilizes a highly cross-linked, closed-cell polymer structure. When integrated as the core insulation of sandwich panels, it restricts convective, conductive, and radiative heat transfer. By maintaining a closed-cell ratio exceeding 95%, our high-density panels retain their thermal properties over decades of operation. This whitepaper explains our design, material science, and engineering principles, showcasing how we deliver reliable containment for global cold chains.
Utilizing high-density polyurethane (40–42 kg/m³) to achieve a thermal conductivity lambda value ($\lambda$) as low as 0.021 W/m·K. This ensures minimal temperature drift and significantly lowers refrigeration power consumption.
Equipped with eccentric cam-lock structural hooks or double tongue-and-groove joints. The air-tight seals eliminate thermal bridging, preventing condensation, mold development, and envelope failure.
Providing advanced PIR core formulas matching the ASTM and European Class B-s1, d0 fire rating criteria. PIR forms a carbonized char layer under direct flame exposure to retard flame propagation.
A Pioneer in Thermal Enclosure and Energy-Efficient Refrigeration Engineering
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.
Our business in refrigeration fields started in 1996, with more than 20 years experience in refrigeration industry, we are confident in our professionality. And our factory is specializing in refrigeration manufacturing and technology.
Comprehensive technical data for architects, consultants, and procurement managers evaluating design criteria.
High-throughput continuous panel press systems and quality control infrastructure.
Operating out of our 60,000 square meter standardized production hub, our facility utilizes continuous automatic double-belt production technology. Unlike old, manual discontinuous molds, our automated lines provide uniform pressure and heating during the liquid polyurethane injection phase. This ensures even density distribution and helps prevent panel deformation over time.
With about 180 workers and 10 QC team, the quality and efficiency are guaranteed of our products. And we are always aiming for higher quality products and better service. Now, the factory has 4 standardized workshops, high quality and efficient production equipment, as well as advanced production lines and techniques. Our factory mainly produces PIR (Polyisocyanurate) and PU (Polyurethane) sandwich panels, cold storage doors, air coolers, condensers, condensing units, compressor units etc.
By sourcing raw steel coils and MDI chemicals from top suppliers (like Baosteel and Wanhua Chemical), we protect our supply chain from cost volatility. Our automated processes keep panel thickness tolerances within ±1mm and cut overall manufacturing lead times to 7–15 working days. This speed and precision support large global infrastructure projects.
Tailoring modular wall systems and cooling machinery to meet specialized industry requirements.
Optimized storage environments for fruits and vegetables. Balanced atmospheric systems use 100-150mm PU panels to control gas and moisture infiltration, maintaining produce quality and extending shelf life.
High-traffic distribution facilities require robust wall systems. Our thick-skinned steel panels resist mechanical impacts and structural fatigue from frequent forklift operations and temperature variations.
Strict temperature and hygiene control. Cleanroom profiles feature flush ceiling designs, anti-microbial coatings, and fully sealed panel joints that prevent dust accumulation and air leakage.
Our commitment to sustainable development, greener raw materials, and next-generation insulations.
The global shift toward green building standards is transforming the industrial insulation sector. To meet these demands, we are upgrading our core polyurethane chemistry to use hydrofluoroolefins (HFOs) as blowing agents instead of standard hydrofluorocarbons (HFCs). This transition reduces the Ozone Depletion Potential (ODP) to zero and lowers the Global Warming Potential (GWP) to under 1, helping our clients meet international environmental regulations.
We are also researching structural bio-resins that replace petroleum-derived polyols with soy or castor oil extracts. Additionally, we are developing smart wall panels with embedded micro-sensors. These sensors monitor temperature gradients, joint strain, and moisture levels in real time, alerting facility managers to insulation leaks before thermal failures can occur.
Over two decades of growth, technological upgrades, and manufacturing expansion.
Our founder started the business from refrigeration equipment marketing and installation.
With our first factory completed in Shaanxi, we produced our first cam-lock sandwich panels.
The second factory in LanZhou completed, our business started to cover the whole north-west market in China.
Follow with larger business and international business, the Shaanxi factory relocated to a larger fields, now we possess with 120 acers area with 8 advanced workshops.
With more advanced technology in insulation panel industry, we input our first automatic split -joint production line. Here the new chapter begins.
Our second advanced automatic production line put on stream, we reach to a higher productivity and efficiency with better quality.
With the responsibility of sustainability, we are now moving into an eco-friendly factory, enhancing our green manufacturing standards.
Streamlined B2B importing processes and compliance frameworks for global procurement officers.
Industrial procurement teams require complete regulatory compliance and transparent shipping processes. Our product lines hold CE Certification, ISO 9001:2015 Quality Management status, and strict fire performance classification documents.
For global logistics, our panels are packed with protective PE films and heavy-duty cardboard edge-guards on reinforced wooden pallets. This packaging minimizes risk of face metal scratching or denting during sea transit and port handling.
We supply full CAD project drafting, load-span structural calculations, and step-by-step layout drawings for international building projects. Our engineering team assists with remote installation planning, ensuring your local contractors can build quickly and without error.
Technical answers regarding material properties, mechanical values, installation, and procurement logistics.
High-capacity evaporators, compressor units, and industrial walk-in doors designed to optimize cold storage performance.
