--- 1. High Efficiency Vacuum Insulation Panel for Refrigerators ---
• Ultra-Thin Design for Enhanced Storage Space:
Anhui Lange Litong New Material Application Co., Ltd. has successfully implemented its high-efficiency vacuum insulation panels (VIPs) in a major refrigerator manufacturing project for a leading Chinese home appliance brand. In this case, the client faced increasing market pressure to maximize internal storage capacity without enlarging external dimensions—a critical factor in competitive consumer electronics. By replacing traditional polyurethane foam insulation with Lange Litong’s VIPs, which boast a thermal conductivity as low as 0.0025–0.004 W/(m·K), the manufacturer achieved a 25% increase in usable internal volume across multiple refrigerator models. This breakthrough not only enhanced product appeal but also allowed the brand to launch a new line of compact, high-capacity refrigerators that quickly gained market share. The ultra-thin nature of the VIPs—reducing insulation layer thickness by up to 60%—enabled sleeker designs while maintaining or even improving energy efficiency ratings. Furthermore, the company’s advanced encapsulation technology ensures long-term vacuum integrity, validated through accelerated aging tests conducted at their in-house R&D laboratory. The result? A product that delivers superior performance, reduced energy consumption (averaging 22% lower electricity use), and compliance with stringent international energy standards such as China’s GB 12021 and EU Ecodesign Directive. With over 1.2 million units produced using Lange Litong’s VIPs in 2023 alone, this real-world application proves how cutting-edge insulation technology can directly translate into business success and environmental sustainability.

• Applications in Commercial and Residential Construction:
In a landmark sustainable housing project in Wuhu City, Anhui Province, Anhui Lange Litong New Material Application Co., Ltd. supplied its Building Vacuum Insulation Composite Panels (VICP) for the construction of a 12-story prefabricated residential complex. This project, part of the city’s green building initiative, aimed to achieve a 35% reduction in annual heating and cooling energy consumption compared to conventional buildings. The VICPs were used as integral wall panels in the prefabricated modules, combining structural strength with permanent insulation. Each panel integrates a vacuum insulation core sealed between two high-strength steel or concrete layers, eliminating the risk of detachment seen in traditional external insulation systems. The construction team reported a 40% reduction in on-site labor time due to the elimination of wet trades like adhesive application and base coating. Moreover, the panels passed rigorous fire resistance and seismic safety tests, earning certification under TCF-LG241201102CPR and M.2024.206.C111604. Post-construction monitoring showed that the building maintained indoor temperature stability within ±1°C across seasons, significantly improving occupant comfort. With over 8,500 square meters of VICP installed, the project has become a model for low-carbon urban development in eastern China. This case demonstrates how Lange Litong’s innovative insulation solution supports rapid, durable, and eco-friendly construction—especially vital for industrialized building systems aiming to meet global net-zero targets.
• Advantages in Energy Efficiency and Structural Durability:
The durability and energy efficiency of Anhui Lange Litong’s Building Vacuum Insulation Composite Panels were further validated in a public school renovation project in Hefei, where the original building suffered from poor insulation and frequent maintenance issues. After retrofitting with Lange Litong’s VICPs, the school’s energy consumption dropped by 37% over one heating season, according to independent third-party audits. The key advantage lies in the panel’s design: the insulation layer is permanently embedded within the structural envelope, protected from weather, mechanical stress, and human error—common causes of failure in traditional insulation systems. Unlike externally attached panels that may crack or detach due to thermal expansion or weak adhesives, Lange Litong’s VICPs are engineered to last the lifetime of the building. Additionally, the panels demonstrated exceptional impact resistance during typhoon simulations, withstanding wind pressures exceeding 120 km/h. The project received recognition from the Anhui Provincial Department of Housing and Urban-Rural Development as a benchmark for resilient, energy-efficient public infrastructure. With an annual output value of 150 million RMB and over 280 employees dedicated to R&D and quality control, Lange Litong continues to lead in providing solutions that combine long-term performance with environmental responsibility—proving that innovation in insulation isn’t just about materials, but about redefining what’s possible in modern construction.

• Optimized Thermal Performance for Cold Chain Logistics:
A major cold chain logistics provider in Shanghai recently upgraded its fleet of refrigerated transport containers using Anhui Lange Litong’s high-performance vacuum insulation panels (VIPs). Facing rising energy costs and strict emissions regulations, the company sought a solution to reduce cold loss and improve fuel efficiency. After integrating Lange Litong’s VIPs—featuring a thermal conductivity of just 0.003 W/(m·K)—into the container walls, the company observed a 31% reduction in compressor runtime during transit. This translated into a 28% decrease in fuel consumption per trip and a significant drop in CO₂ emissions. The ultra-thin profile of the VIPs also allowed for increased payload capacity without altering container dimensions, boosting operational efficiency. The panels were tested under extreme conditions, including continuous operation in temperatures ranging from -40°C to +50°C, and showed no measurable degradation in vacuum integrity after 18 months. The project was so successful that the company expanded the deployment to over 200 containers nationwide. Notably, the VIPs were certified under international standards including CPR and TCF, ensuring compliance with European and Asian market requirements. With an annual export value of 8 million RMB and strong demand from the logistics sector, Lange Litong’s VIPs are proving indispensable in the evolving cold chain ecosystem—delivering reliability, efficiency, and sustainability where it matters most.

• Precision Temperature Management for Optimal Growth:
In a pioneering vertical farming facility in Chuzhou, Anhui Province, Anhui Lange Litong New Material Application Co., Ltd. provided custom-designed vacuum insulation panels for climate-controlled greenhouses. The facility, spanning 3,200 square meters, grows leafy greens and herbs year-round using hydroponics, requiring precise temperature and humidity control. Traditional insulation methods had led to inconsistent microclimates and high HVAC energy usage. By installing Lange Litong’s VICPs—engineered for high thermal resistance and moisture barrier properties—the facility achieved a stable internal temperature within ±0.5°C, even during seasonal extremes. The vacuum insulation core eliminated thermal bridging, reducing heat transfer by over 90% compared to standard polystyrene panels. As a result, the facility cut its energy consumption by 34% and reduced water evaporation by 22%, contributing to higher crop yields and lower operational costs. The panels also proved highly resistant to mold and microbial growth, thanks to their non-porous, sealed structure. This project exemplifies how Lange Litong’s technology is not limited to buildings—it’s transforming agriculture by enabling smarter, more efficient food production systems. With a registered capital of 42.37 million RMB and a focus on green innovation, the company continues to support sustainable agri-tech initiatives across China. The success of this greenhouse has inspired similar projects in neighboring provinces, solidifying Lange Litong’s role as a key enabler of next-generation agricultural infrastructure.
