Zerothermo Technology Co., Ltd., a national high-tech enterprise, is headquartered in the Beijing Economic-Technological Development Area, with our primary manufacturing base in Nanchong City, Sichuan Province. We operate one of the largest and most advanced production centers in China for high-vacuum insulation solutions.
As an industry leader in R&D and production, we supply cutting-edge vacuum insulated panels (VIPs), thermal management structures, and tailored components designed to support global carbon neutrality goals. Our specialized structural engineering and materials science enable extremely low thermal conductivity performance ($<0.004 \text{ W/(m}\cdot\text{K)}$) across cold chain, aerospace, commercial architecture, and advanced industrial heating systems.
Vacuum Insulated Panels (VIPs) represent the pinnacle of modern thermal engineering, providing up to ten times the thermal resistance of traditional insulation materials such as mineral wool, EPS, or polyurethane foam. By extracting air from a microporous core material and encapsulating it within a high-barrier, multi-layer envelope, heat transfer via conduction, convection, and radiation is almost entirely eliminated.
Current industrial trends indicate a rapid shift from traditional fiberglass cores toward fumed silica cores. Fumed silica cores offer significant structural and longevity benefits: they are non-combustible, exhibit higher resistance to puncture and mechanical stress, and maintain their thermal performance for over 50 years. This makes them ideal for building envelope retrofits, refrigeration, and specialized industrial containment systems where replacement is cost-prohibitive.
Fumed silica VIPs operate on the principle of the Knudsen effect. When the mean free path of gas molecules becomes larger than the pore size of the core matrix (typically ~10nm for fumed silica), thermal conduction drops to near-zero levels, even at partial vacuum pressures. This ensures long-term stability compared to fiber-based cores, which require extremely high vacuums (<1 mbar) that are difficult to maintain over decades.
Enterprise procurement departments face growing pressure to comply with stringent regional energy standards, such as the EU's Energy Performance of Buildings Directive (EPBD) and the US DOE's strict cold chain pharma specifications. Industrial procurement parameters focus heavily on:
At Zerothermo's Nanchong facility, our manufacturing line integrates advanced automation under Factory 4.0 principles to deliver reliable, high-capacity outputs. Vacuum sealing chamber automation, inline pressure measurement, and laser-guided sizing tools guarantee that every VIP meets exact tolerance thresholds.
By keeping the entire production chain in-house—from core preparation and dry-pressing to multi-layer film lamination and ultimate vacuum extraction—we protect global buyers from supply chain shocks. Our manufacturing scale allows us to provide custom shapes, round profiles, and complex cuts without the premium lead times typical of smaller regional suppliers.
Beyond traditional planar insulation panels, industrial applications often require specialized structural interfaces. Leveraging the capabilities of our parent enterprise, CBVAC Group, Zerothermo offers custom-machined mechanical interfaces, including non-standard and shaped flanges. Produced precisely according to architectural or machine drawings, these components ensure hermetic seals and eliminate thermal bridging in ultra-cold systems and high-vacuum lines.
