• Refrigeration and Cold Storage:

Our vacuum insulation panels have been successfully deployed in high-performance refrigeration systems worldwide, transforming how cold storage is engineered. One notable case involved a large-scale medical cold chain facility in Southeast Asia, tasked with storing vaccines requiring strict temperature control between 2–8°C. Traditional insulation methods failed to maintain stability during peak summer heat, risking product integrity. By retrofitting the facility’s storage units with Anhui Lange Litong’s VIPs, the system achieved a 99.6% temperature consistency rate over 12 months, even under extreme ambient conditions. The ultra-thin profile allowed for additional shelf space, increasing storage capacity by 18%. Furthermore, the facility reported a 30% reduction in compressor runtime, translating into substantial electricity savings and lower maintenance needs. Another success story comes from a premium freezer manufacturer in Germany, which adopted our VIPs in their high-end home appliances. Post-integration testing revealed a 26% improvement in energy efficiency compared to previous models, enabling the company to secure CE certification and gain market share in the EU green appliance segment. These real-world implementations demonstrate how our VIPs deliver measurable performance gains, reliability, and compliance—making them the preferred choice for mission-critical refrigeration and cold chain applications globally.

• Construction and Prefabricated Buildings:

Anhui Lange Litong’s Building Vacuum Insulation Composite Panels (VICPs) are revolutionizing modern construction, particularly in prefabricated and industrial buildings. A landmark project in Wuhan, China, involved the construction of a 12-story residential complex using our VICP-based sandwich wall panels. Unlike traditional external insulation systems prone to cracking and detachment, our panels integrate the insulation layer within concrete or steel layers, ensuring a lifespan aligned with the building structure. The project was completed 40% faster than conventional methods due to the industrialized prefabrication process, with minimal on-site wet trades. Energy audits conducted after occupancy showed a 34% reduction in heating and cooling loads compared to similar buildings using standard insulation. Notably, no maintenance was required for the insulation layer over two years—proving the “lifetime maintenance-free” claim. Another application was in a climate-controlled greenhouse for high-value vegetable cultivation in Hebei Province. The VICPs maintained stable internal temperatures year-round, reducing energy use for heating by 38% while improving crop yield by 22%. These projects validate our technology’s robustness, energy efficiency, and long-term value in both urban housing and modern agriculture, reinforcing our position as a key enabler of low-carbon, high-performance construction.

• Energy Efficiency and Environmental Protection:

At Anhui Lange Litong, sustainability is not just a goal—it’s embedded in every product we develop. Our vacuum insulation panels are engineered to drastically reduce energy consumption across industries, directly contributing to global carbon reduction targets. For instance, in a pilot project with a commercial shopping center in Hangzhou, replacing traditional insulation with our VICPs led to a 31% drop in HVAC energy usage over a full year. This equates to approximately 120 tons of CO₂ emissions avoided annually—equivalent to planting over 2,000 trees. In the refrigeration sector, our VIPs have helped clients exceed international energy efficiency benchmarks, such as ENERGY STAR and A+++ ratings. One major appliance brand in Europe reported a 28% decrease in lifetime electricity costs per unit after switching to our VIPs, enhancing both environmental performance and consumer appeal. Beyond energy savings, our products are manufactured using non-toxic, flame-retardant raw materials certified under EU REACH and RoHS standards. We also ensure zero hazardous waste in production through closed-loop recycling of packaging and scrap materials. These efforts align with our broader mission: to provide insulation solutions that don’t just insulate buildings or appliances—but help protect the planet. Every panel we ship carries a promise of sustainability, efficiency, and responsibility.

• Recycling Initiatives in Insulation Materials:

Anhui Lange Litong is at the forefront of sustainable innovation, actively developing recycling pathways for insulation materials. Recognizing the growing challenge of end-of-life insulation waste, we launched a groundbreaking R&D initiative in 2023 focused on incorporating recycled glass fiber and post-consumer fumed silica into our VIP core materials. Early trials demonstrated that up to 45% of virgin raw materials could be replaced without compromising thermal performance—maintaining thermal conductivity below 0.004 W/(m·K). In a joint pilot with a European recycling partner, we successfully processed 15 tons of decommissioned insulation panels from old refrigerators and buildings, extracting usable materials for new VIP production. The recycled panels met all quality standards and passed accelerated aging tests with flying colors. This initiative not only reduces landfill burden but also lowers the carbon footprint of our manufacturing process by 22%. We are now working toward establishing a circular economy model, offering take-back programs for expired insulation systems and promoting reuse in secondary markets. These efforts reflect our long-term vision: to build a sustainable supply chain where insulation doesn’t just perform today—it contributes to a greener tomorrow.
