Industry-standard components for commercial and industrial cooling applications.
An in-depth look at thermal efficiency, structural integrity, and global logistics optimization.
As the global population grows and food security becomes a paramount concern, the demand for sophisticated "Cold Chain Logistics" has skyrocketed. The modern Sendvič Panel (Sandwich Panel) is no longer just a building material; it is the fundamental thermal envelope that enables the safe storage and transport of medicine, fresh produce, and high-tech components. At Shaanxi YuanShengHeTong, we bridge the gap between architectural stability and thermodynamic efficiency.
Current industrial trends indicate a shift toward PIR (Polyisocyanurate) cores due to their superior fire resistance and lower thermal conductivity (λ values) compared to traditional EPS or standard PU. This shift is driven by stricter global building codes and the urgent need for energy conservation in industrial operations.
Our PIR panels meet rigorous international fire safety standards, providing critical time windows for evacuation and structural protection during thermal incidents.
Utilizing high-density foam cores, we achieve maximum R-values with minimum thickness, optimizing interior space for cold storage facilities.
The synergy between high-tensile steel skins and our proprietary bonding process ensures panels can withstand significant wind loads and structural stresses.
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 factory specializes in refrigeration manufacturing and technology, currently possessing a production site of 60,000 square meters with 4 standardized workshops. Equipped with advanced production lines and techniques, we guarantee the highest quality PIR and PU sandwich panels.
How our Sendvič Panels adapt to diverse environmental and regulatory demands.
In regions like Southeast Asia and Central Asia, preserving post-harvest freshness is vital. Our panels provide the thermal stability required for grape, apple, and vegetable storage, significantly reducing food waste.
Medical-grade cold rooms require zero thermal bridging. Our PIR panels, combined with precision-engineered cold storage doors, maintain the ±0.5°C stability required for vaccine and medicine storage.
Beyond cooling, our panels serve as exterior wall solutions for high-tech manufacturing plants, providing a clean, aesthetic finish with high energy efficiency ratings.
Operating from the industrial heart of Shaanxi, we leverage China's unparalleled steel and chemical supply chains. This allows us to maintain stable pricing and rapid lead times, even amidst global market fluctuations. Our "One-Stop Solution" integrates raw material sourcing with advanced fabrication, ensuring that every panel and cooling unit is built to a unified standard of excellence.
The future of Sendvič Panel manufacturing lies in Smart Insulation. We are currently developing panels with integrated thermal sensors for real-time monitoring of insulation health. Furthermore, our R&D is focused on "Ultra-Low GWP" blowing agents, ensuring that our products not only save energy but are also environmentally benign from the point of manufacture.
We hold CE certifications and adhere to ISO9001 quality management systems. Our products are engineered to comply with European FM approvals and North American ASTM standards, ensuring seamless integration into any international construction project.
Verified quality for peace of mind in industrial applications.
Expert insights into Sandwich Panel selection and maintenance.
While both are polyurethane-based, PIR (Polyisocyanurate) has a higher ratio of isocyanate, resulting in superior fire resistance and slightly better thermal stability compared to standard PUR. Most modern industrial regulations now favor PIR.
With proper installation and maintenance, our panels have a service life exceeding 25-30 years. The galvanized and pre-painted steel skins protect against corrosion, while the closed-cell foam prevents moisture absorption.
Yes. Beyond exporting materials, we offer comprehensive project design and technical consultation. We can provide installation supervisors to ensure your local team adheres to best practices for airtightness and thermal integrity.
Thickness is determined by the temperature delta between the interior and exterior. For example, a -20°C freezer typically requires 120mm to 150mm PIR panels, while a chilled processing room might only require 75mm to 100mm.
