In the modern era of high-precision construction and cold chain management, the 25mm sandwich panel has emerged as a critical component for specialized thermal insulation. While thicker panels cater to industrial deep-freezing, the 25mm variant offers an optimized balance between space efficiency, structural rigidity, and moderate thermal resistance, making it the gold standard for cleanrooms, data centers, and specialized refrigeration units.
As a leading CE-certified factory and exporter, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has spent over two decades refining the chemical composition and manufacturing precision of these panels. Our focus on PIR (Polyisocyanurate) and PUR (Polyurethane) cores ensures that every square meter meets the stringent demands of global energy-efficiency standards.
With 20+ years of expertise, our factory integrates advanced QC protocols and CE certifications to ensure every panel provides maximum information gain for engineers.
Operating from Shaanxi, China, our facility houses 4 standardized workshops equipped with automated split-joint production lines.
From the North-West China market to international logistics hubs, we provide one-stop project solutions for global enterprises.
China has become the epicenter of the global sandwich panel supply chain, not just through scale, but through rapid technological iteration. Our factory in Shaanxi exemplifies this shift:
The industry is moving toward "Carbon Neutral Buildings." 25mm sandwich panels are increasingly used in Passive House designs and modular hospital constructions due to their lightweight nature and excellent R-value-to-thickness ratio. The demand for CE-certified products from China is skyrocketing as European and North American buyers seek reliable, high-volume manufacturing partners who understand international compliance.
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 professional fields include refrigeration of fruits, vegetables, food industry; also large supermarkets, restaurants, hotels, medical and logistics companies.
