In the contemporary era of green construction and cold chain optimization, the Pu Sandwich Panel Machine has emerged as the cornerstone of thermal efficiency. As a leading CE Certification Pu Sandwich Panel Machine Factory, Shaanxi YuanShengHeTong is at the forefront of this industrial revolution. Polyurethane (PU) and Polyisocyanurate (PIR) panels represent the gold standard in insulation, offering a thermal conductivity coefficient lower than any other commercially available material. This section explores the convergence of mechanical engineering, chemical precision, and global compliance.
CE certification is not merely a label; it is a rigorous verification of safety, health, and environmental protection. Our production lines adhere to the Machinery Directive 2006/42/EC, ensuring that every panel produced meets the stringent EN 14509 standards for factory-made insulating sandwich panels.
Standard panels focus on thickness; our advanced machinery focuses on density uniformity. By utilizing high-pressure foaming technology, we achieve a closed-cell rate exceeding 95%, which dramatically reduces thermal bridging and long-term operating costs for cold storage facilities.
While PU offers excellent insulation, our PIR (Polyisocyanurate) technology provides enhanced fire resistance (Class B1/B2). Our machines are engineered to handle the complex chemical reactions required for PIR, delivering a superior safety profile for industrial warehouses.
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 2020 upgrade introduced the dual-belt continuous production system. Unlike discontinuous methods, this allows for infinite panel lengths with microscopic precision in thickness control (+/- 0.5mm), essential for high-rise cold chain logistics centers.
Every batch is subjected to tensile strength tests and dimensional stability analysis. We leverage IoT sensors across our 4 standardized workshops to monitor curing temperatures in real-time, ensuring "Zero Defect" output for global exports.
By 2023, we transitioned toward an eco-friendly factory model. Our machines now utilize Pentane-blown technology, which has zero ODP (Ozone Depletion Potential) and low GWP (Global Warming Potential), meeting the strictest EU environmental mandates.
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.
Relocated to a 120-acre area with 8 advanced workshops to support international trade growth.
Input our first automatic split-joint production line, marking a new chapter in manufacturing efficiency.
Transitioned into a sustainability-focused, eco-friendly manufacturing hub.
Beyond manufacturing, we provide the skeletal structure for the world's most critical temperature-controlled environments.
Ultra-clean cold rooms for vaccine and biological storage. Our panels prevent microbial growth and maintain precise thermal stability.
Post-harvest cooling solutions for fruits and vegetables, extending shelf life and reducing global food waste.
Modular walk-in freezers for large supermarkets and hotels, designed for rapid assembly and maximum energy savings.
Providing the outer shell for large-scale logistics hubs that require both structural integrity and thermal insulation.
Our commitment to E-E-A-T is validated by global regulatory bodies.
Understanding the nuances of local building codes is paramount. For our European clients, we ensure full compliance with EN 13501-1 for fire classification and EN 14509 for mechanical performance. For North American markets, we focus on ASTM standards and FM Global approvals.
