In the current global industrial landscape, the demand for high-efficiency thermal envelopes has transcended simple construction. OEM Sandwich Panelen have become the backbone of the "Green Building" revolution and the "Global Cold Chain" expansion. As an industry-leading manufacturer and exporter, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. recognizes that sandwich panels are no longer just building materials; they are precision-engineered systems designed to mitigate thermal bridging, reduce carbon footprints, and ensure food security.
The global sandwich panel market is undergoing a seismic shift from traditional mineral wool to high-performance Polyisocyanurate (PIR) and Polyurethane (PU) cores. This transition is driven by stringent international energy codes (such as the EU's EPBD) and the necessity for rapid, modular construction in emerging markets across Southeast Asia, the Middle East, and Africa.
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. Our integration of "high quality products, one-stop project solution, engineering advanced services, and international trade" allows us to provide customers with excellent products and satisfied services.
Our expertise spans across diverse professional fields, including the refrigeration of fruits, vegetables, and the food industry. We also serve large-scale supermarkets, restaurants, hotels, medical facilities, and global logistics companies. Since our inception in 1996, we have cultivated over 20 years of experience, establishing ourselves as a cornerstone of the North-West China market and a rising star in the international export arena.
We provide variable density PUR/PIR cores (ranging from 38kg/m³ to 45kg/m³) tailored for specific structural load requirements and R-value targets.
Our proprietary cam-lock design ensures airtight joints, critical for ultra-low temperature environments and pharmaceutical storage.
Options include Food-Grade Stainless Steel, PVDF-coated Galvanized Steel, and Anti-corrosive Aluminum-Zinc alloys for harsh chemical environments.
Utilizing high-pressure foaming technology to ensure zero voids, maximizing the thermal integrity of every panel manufactured.
Widths and thicknesses (50mm to 200mm+) customized to architectural drawings, minimizing on-site waste and cutting time.
Navigating international building codes is a core competency of our export division. Our Sandwich Panelen meet and exceed various regional standards:
With about 180 workers and a dedicated 10-person QC team, we guarantee quality and efficiency. Our existing production site spans 60,000 square meters, featuring 4 standardized workshops equipped with advanced automatic production lines. We specialize in producing PIR and PU sandwich panels, cold storage doors, air coolers, condensers, and condensing units.
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.
The second factory in LanZhou completed, covering the whole north-west market in China.
Shaanxi factory relocated to a 120-acre area with 8 advanced workshops.
Input our first automatic split-joint production line for advanced insulation panels.
Second advanced automatic production line put on stream for higher productivity.
Transitioning into a sustainable, eco-friendly factory model.
Looking ahead, the integration of AI-driven manufacturing and Smart Sensors within sandwich panels is on the horizon. We are researching "Smart Envelopes" that can monitor internal temperature fluctuations and structural integrity in real-time. Our roadmap includes the development of Vacuum Insulation Panels (VIPs) combined with traditional PIR to achieve unprecedented R-values in thinner profiles, catering to the urban "micro-fulfillment" center trend.
PIR (Polyisocyanurate) offers superior fire resistance and slightly higher thermal efficiency (lower K-factor) compared to standard PU (Polyurethane).
Yes, we offer specialized skin coatings like PVDF or stainless steel 316 to resist salt spray and high-humidity corrosion.
Typically, production takes 15-25 days depending on customization requirements, followed by sea freight logistics to your local port.
We provide comprehensive installation manuals, CAD drawings, and video tutorials. For large-scale projects, we can arrange remote technical consultation.
