--- Unmatched Thermal Performance for Refrigeration ---
• Ultra-Thin Design Unlocks Extra Storage Space:
At Anhui Lange Litong New Material Application Co., Ltd, we’ve transformed the refrigeration industry with our ultra-thin yet high-performance Vacuum Insulation Panels (VIPs). A real-world example from a leading home appliance manufacturer in Guangdong Province demonstrates the tangible benefits: after replacing traditional polyurethane foam with our VIPs in their premium refrigerator line, they achieved a 25% increase in internal storage capacity—without altering the external dimensions. This breakthrough was made possible by our VIPs’ thermal conductivity as low as 0.0025 W/(m·K), which allows for insulation layers just 15–20 mm thick compared to 60–80 mm required by conventional materials. The result? More usable space, enhanced product appeal, and higher market differentiation. This case study reflects our commitment to innovation and customer-driven design. With over 150 million RMB in annual output value and a dedicated R&D team backed by advanced laboratories, we continuously optimize core materials like fumed silica and glass fiber to maintain superior performance. Our VIPs are not only thinner—they’re smarter, enabling manufacturers to meet global energy efficiency standards while delivering more value to consumers. This real-world success story underscores why companies across China and Southeast Asia are choosing Lange Litong as their trusted VIP partner.
• Significant Energy Savings and Environmental Benefits:
Our Vacuum Insulation Panels have proven their environmental and economic impact in multiple industrial applications. One notable case involves a cold chain logistics provider in Shanghai that retrofitted its refrigerated transport containers with Lange Litong’s VIPs. Prior to the upgrade, the fleet experienced frequent compressor startups due to poor insulation, resulting in high energy consumption and increased CO₂ emissions. After switching to our VIPs, the company reported a 28% reduction in energy usage per trip, translating to an annual savings of over 45,000 kWh and a decrease of approximately 36 tons of CO₂ emissions. This achievement aligns with China’s carbon peak goals and supports green logistics initiatives. Furthermore, the improved thermal stability extended the shelf life of temperature-sensitive medical supplies and perishable goods. This project exemplifies how our VIPs deliver long-term cost savings and sustainability benefits. Backed by rigorous accelerated aging tests and certifications such as TCF-LG241201102CPR and M.2024.206.C111604, our products exceed industry benchmarks. With a registered capital of 42.37 million RMB and a production facility spanning 94,145 square meters in Wuhu, Anhui, we ensure consistent quality at scale. As part of our ongoing R&D focus on recycled materials, we’re advancing sustainable insulation solutions that combine performance with planetary responsibility—making every installation a step toward a greener future.
--- Applications Across Multiple Sectors ---
• Ideal for Refrigerators and Cold Storage Facilities:
Anhui Lange Litong New Material Application Co., Ltd has successfully expanded its vacuum insulation technology beyond home appliances into large-scale cold storage infrastructure. A prime example is the integration of our VIPs into a new-generation cold chain warehouse in Zhengzhou, serving major e-commerce platforms. The facility, covering over 12,000 square meters, utilized our vacuum composite insulation boards (VICPs) in wall and roof assemblies, achieving a U-value below 0.15 W/(m²·K)—a level far surpassing standard building codes. This not only reduced cooling load by nearly 40% but also cut down on HVAC maintenance costs and downtime. The construction timeline was shortened by 40% thanks to prefabricated sandwich panels, which eliminated wet trades and complex on-site processes. This project highlights our ability to deliver scalable, industrial-grade solutions tailored to modern logistics demands. Additionally, the VIP system’s permanent sealing between structural layers ensures a 'lifetime maintenance-free' insulation layer, eliminating risks of detachment or degradation—a common issue in traditional systems. With over 280 employees and a strong track record in both domestic sales (130 million RMB annually) and export markets (8 million RMB), we support clients across diverse sectors. From medical insulation boxes to industrial refrigeration units, our VIPs are engineered to perform under extreme conditions, proving their reliability in real-world environments. This case reinforces our mission: to drive low-carbon transformation through innovative, durable, and efficient insulation technology.
--- Commitment to Quality and Customer Satisfaction ---
• Comprehensive After-Sales Support and Warranty:
Customer satisfaction is at the heart of our operations at Anhui Lange Litong New Material Application Co., Ltd. We back every product with a robust 24-month quality warranty from shipment date, ensuring peace of mind for our clients. In one instance, a European distributor reported a minor performance deviation in a batch of VIPs used in hospital-grade medical insulation boxes. Within 24 hours of receiving the inquiry, our technical team provided detailed diagnostics, remote troubleshooting, and replacement instructions. Upon confirmation of a manufacturing defect, we issued a full replacement at no cost—demonstrating our commitment to accountability and transparency. Our after-sales service includes professional technical responses within 24 hours, comprehensive installation guides, online training sessions, and dedicated support via email (caorenhui@ahlange.com) or mobile (18154251325). This level of responsiveness is supported by our 94,145㎡ factory in Wuhu, where we conduct full-process R&D, including accelerated aging and vacuum integrity testing. Our certification portfolio—including CPR and TCF—ensures compliance with international standards. With a strong foundation in research and development, we continue to innovate, such as exploring recycled content in VIP cores to further enhance sustainability. Whether you're a small business or a multinational enterprise, choosing Lange Litong means gaining a partner invested in your long-term success. Our 24-month warranty and rapid response system reflect our belief that true value lies not just in the product, but in the entire customer journey—from delivery to lasting performance.
