High-efficiency condensing units, evaporators, and CE-certified sandwich panels manufactured for cold storage operations globally.
In the modern era of global logistics, agricultural trade, and pharmaceutical distributions, cold chain systems serve as critical infrastructure. As international economies push toward carbon neutrality, industrial and commercial structures require insulation systems that minimize energy consumption. Polyurethane (PUR) and Polyisocyanurate (PIR) core sandwich panels have emerged as the gold standard for high-performance thermal insulation.
Our manufacturing methodology focuses on minimizing the global warming footprint while maximizing thermal efficiency. With CE certification, our PUR sandwich panels conform to the stringent safety, health, and environmental protection standards of the European Economic Area, providing structural engineering durability that withstands diverse mechanical stresses.
Rapid urbanization and the rise of automated cold storage hubs have transformed international warehousing specifications. Modern facilities require taller clearance zones, superior structural integrity, and excellent structural fire behavior. Traditional insulation materials struggle to offer the same thermal conductivity ratio in compact profile thicknesses as high-pressure injected PUR core panels.
From large-scale logistics centers in North America to agricultural storage networks across Central Asia and the Middle East, our solutions align with strict compliance parameters. By engineering integrated solutions that combine PUR panels, structural steel layout designs, and high-efficiency refrigeration units, we help global developers achieve optimized thermal boundaries.
Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Besides product manufacture, we also provide comprehensive services like project design, construction, installation, as well as dedicated 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. Our factory is specializing in refrigeration manufacturing and technology, delivering robust mechanical performance for demanding industrial environments.
Our operations are governed by a stringent 10-member Quality Control (QC) team that conducts comprehensive performance tests. We verify fire resistance classification (B1/B2 standard), uniform density distribution (40-42 kg/m³), dimensional stability, and joint sealing accuracy before any shipment leaves our manufacturing base.
Our manufacturing hub relies on automated continuous laminator systems. This state-of-the-art tooling achieves precise polyol-isocyanate component blending, producing uniform foam structural matrices. The resulting sandwich panels prevent air leakage, resist water absorption, and maintain thermal profiles over decades of thermal cycles.
With about 180 workers and a dedicated 10 QC team, the quality and efficiency of our products are guaranteed.

A journey of innovation, expanding from regional installation services to an international manufacturing powerhouse.
Meeting stringent global criteria for structural load-bearing and thermal conservation performance.
Our products conform to the European standard **EN 14509** for self-supporting double skin metal faced insulating sandwich panels. CE Certification guarantees that our panels undergo rigorous testing for fire behavior, water permeability, air permeability, dimensional tolerances, and mechanical load-bearing capacity.
This international verification allows designers, structural engineers, and contractors in Europe, North America, and other regulated markets to specify our panels with confidence. Our documentation includes comprehensive declaration of performance (DoP) data sheets, ensuring seamless customs processing and structural approval workflows.
For countries requiring localized building code compliance, we provide technical dossiers covering structural wind load capacities, thermal resistance ratings (R-values), and fire protection classifications (such as Class B-s1, d0 under European fire standards). We support our customers through every step of regulatory approval.
Engineered for diverse conditions, from blast freezing tunnels to clean laboratory facilities.
High-turnover distribution centers require thick, structurally sound walls to prevent thermal bridges. Our cam-lock PUR panels ensure tight seams, minimizing air exchanges and helping keep energy expenditures down under constant dock door operation.
Hygienic processing environments demand panels with smooth, non-porous facings that withstand high-pressure washdowns and chemical sanitizers. Stainless steel or PVDF-coated steel sheets integrated with our PUR cores satisfy strict hygiene directives.
Precision chemical storage and medical cleanrooms depend on absolute temperature control. Our PIR and PUR panels prevent heat ingress and maintain hermetic boundaries, safeguarding sensitive pharmaceuticals and biological cultures.
Long-term preservation of fruits and vegetables requires humidity regulation and low oxygen levels. The air-tight sealing technology built into our PU panels prevents gas migration, maintaining optimal atmospheric conditions.
Pioneering green, high-performance insulation solutions for tomorrow's structural standards.
1. Zero-GWP Blowing Agents: In step with global environmental initiatives, we are transitioning our entire polyurethane line to fourth-generation Hydrofluoroolefins (HFOs) and advanced cyclopentane systems. This eliminates ozone depletion potential and lowers global warming factors to near zero.
2. Intelligent Sandwich Panels: Our research team is developing panels with integrated fiber-optic temperature sensors. These sensors monitor structural temperature changes in real-time, helping plant operators identify insulation breaches or moisture collection before failures occur.
3. Modular Pre-Engineered Systems: We are expanding our pre-engineered modular panel layouts. By designing integrated wall-to-roof joints, structural profiles, and doorframes off-site, we aim to reduce field construction times by 35%.
4. Hybrid Core Panels: Combining the high structural load-bearing capacity of polyurethane with the extreme fire resistance of mineral wool, our future hybrid cores will deliver specialized fire walls without compromising thermal values.
