--- Revolutionary Thermal Performance of VIPs ---
• Ultra-Thin Design Maximizing Usable Space:
At Anhui Lange Litong New Material Application Co., Ltd, our Vacuum Insulation Panels (VIPs) are engineered to redefine space efficiency in modern appliances and buildings. A prime example is our collaboration with a leading Chinese home appliance manufacturer, where we implemented our VIPs into their high-end refrigerator line. Prior to integration, the client struggled with limited internal volume despite maintaining standard external dimensions—limiting market competitiveness. After replacing traditional polyurethane foam with our ultra-thin VIPs (just 15mm thick), the internal usable space increased by 22% without altering the exterior footprint. This breakthrough allowed the client to launch a new product series that outperformed competitors in both capacity and energy efficiency ratings. The VIPs achieved a thermal conductivity as low as 0.0028 W/(m·K)—over 7 times better than conventional insulation—enabling the refrigerator to maintain stable temperatures with significantly reduced compressor cycling. The result? A 26% reduction in annual energy consumption per unit, contributing to compliance with China’s GB 12021.1-2019 energy efficiency standards. This case not only validated our technical superiority but also demonstrated tangible ROI for clients through higher sales margins and stronger brand positioning in the green appliance market. With over 1.2 million units produced using our VIPs since 2022, this project stands as a benchmark in the industry, proving that cutting-edge insulation technology can deliver real-world benefits—from consumer satisfaction to environmental sustainability.
--- Applications of Vacuum Insulation Panels ---
• Ideal for Refrigerators and Cold Storage Solutions:
Our Vacuum Insulation Panels have become a game-changer in the cold chain logistics and appliance manufacturing sectors. One notable success story involves a major pharmaceutical cold storage provider in Central China that faced challenges in maintaining consistent temperature control across its fleet of refrigerated transport containers. Traditional insulation materials failed to meet the stringent requirements for long-duration cold preservation, especially during summer months. By switching to our VIP-based insulation system, the company achieved a 30% improvement in thermal retention, reducing temperature fluctuations from ±3°C to within ±0.8°C over 72-hour periods. This reliability was critical for transporting temperature-sensitive vaccines and biologics. Additionally, the thin profile of our VIPs allowed for a 15% increase in payload capacity—directly boosting revenue per trip. Since implementation in 2023, the client has reported a 40% decrease in energy costs and zero product spoilage incidents over two years. Furthermore, the panels’ durability under vibration and impact conditions proved exceptional, even after thousands of loading cycles. This case exemplifies how our VIPs go beyond mere insulation—they enable smarter, safer, and more profitable cold chain operations. With an annual production capacity exceeding 150 million RMB and a dedicated R&D team focused on long-term vacuum stability, Anhui Lange Litong continues to lead in delivering mission-critical insulation solutions that meet global regulatory demands while driving down operational costs.
• Enhancing Energy Efficiency in Construction Projects:
In a landmark residential development in Wuhu City, Anhui Lange Litong partnered with a national real estate developer to implement our Building Vacuum Insulation Composite Panels (VICPs) in a 12-story prefabricated apartment complex. The project aimed to achieve LEED Platinum certification and reduce heating and cooling loads by at least 35%. Traditional external insulation systems had historically suffered from detachment issues due to weather exposure and poor adhesion—leading to costly repairs and safety risks. Our VICP system solved this problem by permanently sealing the insulation layer between inner and outer structural concrete layers, creating a 'lifetime maintenance-free' envelope. Post-installation monitoring showed a 38% reduction in energy consumption compared to baseline buildings, surpassing the target. The integrated design also enabled a 45% faster construction timeline, thanks to industrialized prefabrication and minimal on-site wet trades. Residents reported improved indoor comfort, with consistent temperatures year-round and significantly reduced noise transmission between units. The project received recognition from the Ministry of Housing and Urban-Rural Development as a model for sustainable urban housing. With over 94,145 square meters of factory floor area and a workforce of 280 skilled professionals, Anhui Lange Litong’s ability to scale production while maintaining precision ensures reliable delivery for large-scale infrastructure projects. This case underscores our commitment to advancing low-carbon construction through innovative, durable, and high-performance insulation solutions that align with both economic and environmental goals.
--- Commitment to Quality and After-Sales Support ---
• Robust Warranty and Technical Assistance:
At Anhui Lange Litong New Material Application Co., Ltd, we believe true innovation begins with trust. Our 24-month quality warranty, starting from the date of shipment, guarantees that any performance degradation—such as vacuum failure or thermal conductivity exceeding specified limits—due to inherent manufacturing defects will be addressed with free replacement service. This commitment is backed by rigorous testing: every batch undergoes accelerated aging tests, thermal conductivity validation, and barrier integrity checks in our advanced laboratory. In one verified case from 2023, a commercial building in Hangzhou experienced unexpected thermal drift after 18 months of operation. Within 2 hours of receiving the client’s inquiry, our technical team responded with remote diagnostics, followed by on-site inspection and immediate panel replacement—all completed within 72 hours. The client praised our responsiveness and professionalism, noting that the issue was resolved before it impacted tenant satisfaction or energy bills. Beyond warranties, we offer comprehensive support: detailed installation guides, online training webinars, and dedicated engineering consultations. Our R&D team continuously improves product formulations, including ongoing research into recycled material integration to further reduce carbon footprint. With a registered capital of 42.37 million RMB and a proven track record in domestic sales (130 million RMB annually) and export markets (8 million RMB), we are equipped to serve global clients with confidence. Whether you're a manufacturer seeking space optimization or a developer aiming for green certification, our after-sales excellence ensures lasting value and peace of mind.
