Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is a leading-edge factory and enterprise dedicated to the design, manufacturing, and distribution of state-of-the-art insulation panels and complex refrigeration equipment. Beyond pure structural manufacturing, our operations are optimized to deliver end-to-end solutions—encompassing complex architectural design, engineering construction, system installation, and lifecycle after-sales support.
By merging high-performance products, custom-tailored project solutions, advanced engineering capabilities, and global trade compliance, we supply first-rate insulation materials globally. Our main expertise focuses heavily on building envelopes and cold chain facilities for biological preservation, agricultural storage (fruits and vegetables), food processing facilities, large-scale supermarket cold rooms, hotel/restaurant refrigeration, pharmaceutical logistics, and heavy industrial cleanroom systems.
Established in 1996, we bring over two decades of design expertise to the international commercial market. Our advanced manufacturing site in Shaanxi functions as a center of excellence for cold storage materials and thermal insulation.
The modern building envelope demands high thermal insulation, structural integrity, and long service life. By marrying high-grade aluminum skins with high-density polyurethane (PUR) or polyisocyanurate (PIR) cores, our structural sandwich panels deliver superior engineering performance.
Our core insulation materials maintain a continuous uniform density of 40-42 kg/m³. This exact chemical ratio generates closed-cell structures (>95% closed-cells), offering minimal water vapor permeability and keeping structural thermal conductivity down to a low 0.020-0.023 W/m·K.
Utilizing corrosion-resistant alloys (such as 3003 and 5052 series), the external aluminum sheets are finished with anti-corrosive PVDF or fluorocarbon coatings. This guarantees resistance to acidic vapor, high-pressure sanitizing, washdowns, and humid marine environments.
Our walk-in cold rooms and cleanroom envelopes employ high-strength eccentric cam-locks cast directly into the insulation core during injection. This configuration allows airtight interlocking joints, eliminating thermal bridging and speeding up onsite assembly.
Operating a sprawling 60,000 square meter factory base divided into four standardized workshops, YuanShengHeTong integrates advanced engineering with optimized workflow control. Under our smart manufacturing layout, raw materials undergo strict sorting, conditioning, and automatic delivery to our high-capacity continuous lines.
By employing an automatic split-joint manufacturing line alongside computerized Italian-designed high-pressure foaming systems, we achieve uniform flat surfaces and constant structural thickness. This automated process minimizes thickness variations to less than 0.5 mm, resulting in high flatness and consistent insulation values.
Our 10-person dedicated QC team oversees strict internal audits, testing structural shearing limits, dimensional accuracy, fire retardant qualities, and density variations. This smart supply chain structure ensures shorter lead times, high raw material efficiency, and competitive pricing for large projects.
Production Floor Capability Summary:
4 high-capacity assembly workshops producing high-density PU and PIR panels, high-grade sliding/hinged cold room doors, custom evaporator systems, condenser arrays, and heavy industrial compressor setups.Controlled environments necessitate smooth, non-porous cladding surfaces to prevent microbial buildup. Our aluminum-faced sandwich panels with flush profiles are resistant to regular sanitization routines using strong chemicals and solvents.
From high-throughput distribution hubs to modular walk-in freezers, our sandwich structures provide thermal resistance, reducing compressor runtimes. They help maintain strict temperature limits for fresh agriculture, meat, and frozen seafood.
High-bay automated warehouses require tight structural straightness over vertical heights. Our panels are built to withstand high structural wind-loading, high internal static pressure, and load deflection, keeping systems aligned and functional.
Our founder entered the commercial refrigeration space, launching localized equipment marketing, distribution, and cold-storage installation services in western China.
Completed our first dedicated manufacturing base in Shaanxi, producing high-density polyurethane cam-lock sandwich panels and insulated modular structures.
Commissioned our second large-scale factory in Lanzhou, expanding production capacity and supply reach across northwestern industrial markets.
Relocated Shaanxi production to a modern 120-acre facility, housing eight advanced workshops to meet growing international demand.
Transitioned to advanced continuous processes by introducing our first fully automatic split-joint sandwich panel production line.
Installed our second high-speed automated production line, improving density consistency and production capacity for larger B2B orders.
Adapted operations to align with international eco-friendly standards, using green blowing agents and optimized recycling processes.
YuanShengHeTong is continuously investing in product development to meet the evolving demands of structural thermal insulation. Our research focuses on transition pathways, replacing legacy foaming systems with green alternatives.
Using Pentane and Solstice LBA blowing agents, we produce foam cores with near-zero Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP). We are also working on hybrid organic-inorganic composite materials to improve fire-retardant properties toward Class A flame resistance without compromising thermal efficiency.
In addition, we are testing integrated smart sensors embedded during the foaming stage. These sensors track internal core temperature gradient changes and structural stresses in real time, helping B2B clients monitor structural health dynamically.
We align our production with key international certification frameworks, including CE certification, ISO 9001:2015 quality management, and cleanroom performance approvals. These credentials ensure smooth customs clearance and regulatory approval.
We supply CAD layout support, joint detailing analysis, and detailed wind-load calculations tailored to project parameters. This engineering documentation helps onsite contractors install panels efficiently.
Insulated sandwich panels are packaged in protective wrap, edge-guarded, and secured in shipping containers. This minimizes panel damage and surface scratching during transport.
