In the era of semiconductor nanotechnology and pharmaceutical breakthroughs, the role of a Clean Room Sandwich Panel has evolved from simple partitioning to an active component of environmental control. Modern cleanrooms require panels that offer zero outgassing, anti-static properties, and seamless integration with HEPA filtration systems.
The shift from traditional PUR to PIR (Polyisocyanurate) and specialized Rockwool cores reflects the growing demand for higher fire safety ratings (FM Approved) and superior R-values. As a leading China exporter, we provide materials that meet stringent international standards for thermal stability and structural integrity.
Speed-to-market is critical. The industry is moving towards 100% modular designs. Our Cam-lock sandwich panels allow for rapid assembly and disassembly, facilitating facility expansion or relocation with minimal disruption to controlled environments.
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 business in refrigeration fields started in 1996, with more than 20 years experience in refrigeration industry, we are confident in our professionality. And our factory is specializing in refrigeration manufacturing and technology.
China's clean room industry benefits from an unparalleled upstream and downstream ecosystem. From the raw chemical precursors for PIR/PUR foam to the precision steel rolling mills, every component is sourced within a 200km radius, drastically reducing lead times and costs compared to European or American counterparts.
As mentioned in our history, the transition to automatic split-joint production lines ensures that every sandwich panel has a micron-level precision fit. Automated foaming processes guarantee uniform density, which is critical for maintaining thermal equilibrium in high-precision cleanrooms.
Whether it's a specific RAL color for branding or a non-standard panel thickness for ultra-low temperature storage, Chinese factories offer a level of flexibility that remains cost-effective even at low order volumes.
Our panels are designed to withstand aggressive decontamination protocols, including vaporized hydrogen peroxide (VHP) sterilization. The smooth, non-porous surfaces prevent microbial growth, making them ideal for ISO 5 to ISO 8 environments.
Electrostatic discharge (ESD) can ruin billion-dollar chip batches. We provide panels with permanent anti-static coatings and conductive cores to ensure a safe environment for microelectronics assembly.
Leveraging our 20+ years in refrigeration, we offer integrated solutions where PIR panels work in harmony with our OEM condensing units and air coolers to maintain precise temperature zones for perishable logistics.
Beyond manufacturing, we provide Project Design, Construction, and Installation. This holistic approach ensures that the interface between panels, doors, and refrigeration equipment is seamless, eliminating thermal bridges and air leaks that compromise efficiency.
Our commitment to quality is backed by international certifications, ensuring that our products meet the highest safety and performance standards for global export.
While both are polyurethane-based, PIR (Polyisocyanurate) has a higher ratio of isocyanurate, giving it significantly better fire resistance and thermal stability compared to PUR. PIR is often the preferred choice for high-value cleanroom projects.
We utilize a precision cam-lock system combined with high-quality gaskets and tongue-and-groove joints. During installation, we use specialized cleanroom-grade sealants to ensure zero air leakage, vital for maintaining pressure differentials.
Yes, our PIR panels are specifically designed for high-performance insulation. We adjust the foam density and panel thickness (up to 200mm) to ensure energy efficiency even in blast freezers.
With our dual automatic production lines and 60,000 sqm facility, we can typically fulfill standard orders within 15-20 days. Shipping time depends on the destination port.
