Engineered for excellence, certified for the global market.
In the modern landscape of thermal insulation, the 20mm sandwich panel has emerged as a critical component for high-precision environments. While thicker panels dominate large-scale cold storage warehouses, the 20mm variant offers a unique blend of structural rigidity and space-saving efficiency that is indispensable for cleanrooms, HVAC ducting, and specialized modular partitions.
As a leading CE Certification 20mm Sandwich Panel Manufacturer, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has pioneered the integration of Polyisocyanurate (PIR) and Polyurethane (PUR) cores within this slim profile. Our panels are not merely building materials; they are engineered thermal barriers designed to meet the rigorous demands of the "Zero-Emission" global initiative. By leveraging advanced cam-lock mechanisms and high-density foam injection, we provide a solution that minimizes thermal bridging—a common failure point in traditional insulation methods.
Global exporters now prioritize CE Certification as a non-negotiable benchmark for reliability. This certification ensures that our 20mm sandwich panels comply with European safety, health, and environmental protection standards, facilitating seamless entry into international markets from the EU to Southeast Asia.
The transition from standard PU to high-index PIR has revolutionized fire safety ratings (B1/B2), making 20mm panels safer for high-occupancy industrial zones.
Global buyers are moving away from simple "product sourcing" to "systematic solutions," demanding integrated data on U-values and life-cycle costs.
Post-pandemic logistical shifts have increased demand for "Flat-Pack" insulation kits where 20mm panels serve as the primary lightweight envelope.
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.
Implementing machine learning algorithms to detect micro-cavities in the 20mm foam core during the injection process.
Development of bio-based resins for external panel skins to further reduce the carbon footprint of industrial construction.
Integrating aerogel technology within the 20mm profile to achieve R-values equivalent to 100mm traditional materials.
Founder started business in refrigeration equipment marketing and installation.
First factory completed in Shaanxi, produced first cam-lock sandwich panels.
Second factory in LanZhou completed, covering north-west China market.
Relocated to a larger field, possessing 120 acres area with 8 advanced workshops.
Input first automatic split-joint production line for insulation panels.
Second advanced automatic production line put on stream for higher productivity.
Transitioned into an eco-friendly factory with a focus on sustainability.
We provide localized technical documentation for global exporters. Whether it's complying with Saudi Arabia's SASO standards or the EU's EN 13165 benchmarks, our 20mm sandwich panels are supplied with comprehensive test reports (Fire, Sound, and Thermal).
Beyond panels, we offer full-spectrum support including condensing units and air coolers. This holistic approach ensures that the 20mm partition works in harmony with the refrigeration equipment, optimizing overall energy COP (Coefficient of Performance).
20mm panels are ideal for internal partitions, cleanrooms, and HVAC ducts where space is at a premium but thermal integrity must be maintained. They provide a lightweight yet rigid alternative to traditional masonry or thin metal sheets.
Yes, our CE Certification for PIR/PU sandwich panels ensures they meet the Essential Requirements of the relevant European health, safety, and environmental protection legislation.
Our specialized cam-lock mechanism for 20mm panels is downsized to fit the profile without compromising pull-strength, ensuring an airtight seal that is critical for cold storage efficiency.
With our dual automatic production lines, we typically fulfill large-scale export orders within 15-25 business days, depending on the customization and volume.
