Condensation-free transparency,improves the vision and efficiency of cold chain systems in multiple dimensions. Remain condensation-free when the temperature difference between the two sides exceeds 70℃, keeping away from condensation.
Ultra-low dew point
In contrast to the condensation problem suffered by insulated glass due to the temperature difference between the two sides of the glass, LandVac is free from condensation issues thanks to its high-vacuum chamber.

Remain condensation-free when the temperature difference between the two sides exceeds 70℃, keeping away from condensation;

Allowing high-end refrigerators, observation windows, and other cold chain systems to have a great visual effect.

Note: Test conditions: Indoor temperature at 25℃, outdoor temperature at -50℃, with relative humidity at 70%.  

Ultra-low dew point
Energy Conservation
Reduce the costs for dew cleaning and defrosting and put extra power consumption under control.

Thanks to the high vacuum chamber of LandVac, which effectively blocks the thermal transmission,the thermal insulation performance of LandVac is 2-4 times better than insulated glass and 6-10 times better than single pane glass, significantly reducing heat exchange and boosting the energy efficiency of cold chain appliances.

Energy Conservation
Thin and lightweight structure
A piece of 8.3 mm thick LandVac weighs only 20kg/㎡, light and aesthetic.

In comparison with triple-pane insulated glass, LandVac has only a quarter of its thickness and weighs at least 10 kg less per square meter while managing a better U-value. It effectively reduces the use of hardware, allowing a variety of refrigeration appliances to have a perfect combination of functionality with an elegant appearance.

Noise Reduction
With its weighted sound reduction index exceeding 39 dB, LandVac makes rooms in downtown quiet like a library.

Thanks to the high vacuum chamber of LandVac , which effectively blocks the sound transmission, LandVac has remarkable acoustic properties against high penetrative medium and low-frequency noises such as traffic and construction noises, much better than that of insulated glass. 

Noise Reduction
Tempered and Safe
Completely retains the high strength, impact resistance, and other safety characteristics of tempered glass with its unique FLAS Flexible Lead-free Alloy Sentry technology

The surface stress and fragmentation test of LandVac conform with the standard of tempered glass with wind pressure resistance up to 7200Pa, fully meeting the requirements of the national standard.

Tempered and Safe
Outstanding Environmental Adaptability
Since there is no thermal expansion or contraction in the high vacuum chamber of LandVac, the use of LandVac is not limited by geographical locations, elevation, or installation angle.

Furthermore, unlike insulated glass, whether it’s mounted horizontally or at an angle, the U-value of LandVac remains constant, which ensures excellent energy-saving effect,especially suitable for skylights, sunroom, daylighting roof, and applications in other special spaces.

Outstanding Environmental Adaptability
Super Long Life
The service life expectancy of LandVac exceeds 25 years.

By using flexible edge sealing materials, LandVac overcomes the seal failure problem caused by fragile sealing materials especially in the environment with big temperature difference between the inner and outer glass surfaces. Moreover, with the assistance of built-in high efficiency getter material, it can sustain a high level of vacuum for a long time.

Super Long Life
Lead-free
The Testing Report from CTI, which is authorized by RoHS EU, has witnessed the outstanding environmental-friendly performance of LandVac.

CTI testing concludes that the metal sealing material is lead-free, hazard-free, and food-grade safe.
