In the modern cold chain industry, thermal integrity is not just a requirement; it is a critical factor for operational efficiency and food safety compliance. CE Certified Cam Lock Cold Room Panels represent the pinnacle of modular refrigeration construction. Unlike traditional continuous line panels, cam-lock systems utilize a high-strength eccentric hook mechanism embedded within the polyurethane (PU) or polyisocyanurate (PIR) core during the foaming process.
This technical configuration allows for a "tongue and groove" assembly that ensures a hermetic seal. From a thermodynamic perspective, the cam-lock mechanism minimizes "thermal bridging," a common phenomenon where heat leaks through panel joints, causing compressor overwork and increased energy costs. For global enterprises, choosing a manufacturer that integrates CE (Conformité Européenne) standards ensures that the panels meet rigorous safety, health, and environmental protection requirements.
China is home to the world’s most advanced automated PIR/PU production lines. With factories spanning over 60,000 square meters, we achieve economies of scale that reduce unit costs while maintaining precision engineering. Our Shaanxi and Lanzhou facilities are optimized for high-volume international orders.
Since 1996, the evolution from basic refrigeration to AI-integrated cold storage has been driven by Chinese manufacturing. We specialize in custom-engineered solutions, including FM-approved fire-resistant panels and specialized coatings for corrosive environments (e.g., seafood processing).
By sourcing from a manufacturer like Shaanxi YuanShengHeTong, you gain access to an entire ecosystem: from the sandwich panels themselves to condensing units, evaporators, and intelligent control systems. This one-stop project solution minimizes logistics complexity.
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.
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 an existing production site of 60,000 square meters, 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.
Founder started business in refrigeration marketing and installation.
First factory in Shaanxi completed; produced first cam-lock sandwich panels.
Second factory in LanZhou completed, covering north-west China market.
Shaanxi factory relocated to 120-acre area with 8 advanced workshops.
First automatic split-joint production line introduced.
Second advanced automatic production line put on stream.
Moving into an eco-friendly factory model with a focus on global sustainability and CE certification expansion.
The global cold storage market is shifting from mere "refrigerated space" to "intelligent cold chain assets." Our solutions cater to this evolution through:
1. AI Integration: Panels with embedded sensors to monitor moisture and heat flux in real-time.
2. Prefabricated Modularization: Rapid-deploy cold rooms using cam-lock panels that reduce installation time by 60%.
3. Green Blowing Agents: Transitioning to Pentane-based foaming to achieve zero ODP (Ozone Depletion Potential).
In Southeast Asia and Africa, our high-density panels provide extreme insulation against high ambient temperatures, preserving tropical fruits like Durian and Mango for export.
UV-resistant exterior coatings on our PIR panels ensure longevity in desert environments where solar radiation can degrade standard materials within years.
CE certified panels meeting strict EU fire safety regulations (EN 13501-1) are ideal for supermarket chains and urban distribution centers.
