In the global cold chain logistics and food processing industry, the integrity of thermal insulation is non-negotiable. As a premier CE Certification Cold Room Sandwich Panel Factory, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has stood at the forefront of refrigeration technology since 1996. Our PIR and PUR sandwich panels are engineered to meet the rigorous demands of modern environmental standards, providing unmatched R-values and fire safety.
With over 20 years of expertise, we don't just manufacture panels; we provide "Information Gain" through comprehensive technical white papers and engineering support, ensuring our clients from Europe to Southeast Asia achieve maximum energy efficiency and operational longevity.
Our production base spans 60,000 square meters with four standardized workshops. Utilizing two advanced automatic split-joint production lines, we guarantee consistent quality and high-volume output to support global infrastructure projects.
Our Polyisocyanurate (PIR) panels represent the pinnacle of fire safety (Class B1), offering superior char-forming properties compared to standard Polyurethane (PUR). Both materials feature a closed-cell structure (>95%) that inhibits moisture absorption, crucial for maintaining thermal conductivity (λ ≈ 0.020 - 0.022 W/m·K) over decades of use.
For European and international markets, CE certification is more than a label—it's a guarantee of health, safety, and environmental protection. Our panels undergo rigorous testing for mechanical strength, thermal resistance, and fire behavior (EN 14509), ensuring compliance with EU building regulations and local safety codes.
Since 2006, we have perfected the cam-lock mechanism. This system allows for rapid "on-site assembly," reducing labor costs by up to 40% while ensuring a hermetic seal that prevents thermal bridging, a common failure point in inferior panels.
Founder initiates refrigeration marketing and installation services.
First Shaanxi factory operational; production of cam-lock sandwich panels begins.
Relocation to 120-acre facility with 8 advanced workshops for international scale.
Implementation of automatic production lines and pivot to eco-friendly manufacturing.
Expanding into international markets requires deep knowledge of local compliance. We provide full documentation for ASTM, FM, and ISO standards. Our engineering teams offer remote localized support, assisting with wind load calculations and seismic reinforcement designs specifically tailored for regions like the Middle East or Latin America.
Being based in China allows us to leverage the world's most robust industrial ecosystem. We integrate "one-stop project solutions"—from PIR panels to Bitzer/Copeland compressor units—drastically reducing procurement complexity. Our proximity to major shipping hubs ensures optimized logistics and competitive "factory-direct" pricing.
The industry is moving toward Sustainability. We are transitioning to eco-friendly blowing agents with Zero ODP (Ozone Depletion Potential). Modern cold rooms are also becoming "Smart," integrating IoT sensors with our panels to monitor real-time thermal performance and structural health.
Precise temperature control (2°C to 8°C) is vital. Our seamless PUR panels ensure zero thermal leakage for vaccine and blood plasma storage.
High-humidity environments require corrosion-resistant skins. We offer stainless steel or food-grade PET coatings for sustainable agriculture.
For large-scale warehouses, our 150mm-200mm thick panels provide the structural integrity and insulation needed for blast freezers (-40°C).
