The Radi-Cool radiative cooling metamaterial features a high solar reflectivity and a high-infrared emissivity accros the atmospheric window. It establishes an efficient radiative heat transfer channel between the object and the cold Universe. Without additional energy input, the metamaterial cools object even under direct sunlight.
Radi-Cool Zero-Consumption Cooling Technology is a patented technology in USA, China, and all other Southeast Asian countries. The first product line was set up in Colorado, USA, while the massive product line was set up in China, and now Gemar introduces it to the Philippines.
Radiative Cooling Technology
Heat is continuously transmitted to the cold Universe in the form of infrared thermal radiation through the atmospheric window. It can cool an object 30 degree Celsius lower than its temperature at a given time
Infrared radiation through atmospheric transmission window is significantly enhanced by controlling the interactions of electromagnetic waves with micro/nano structures.
Organic-Inorganic Hybrid Structure
Environment-friendly product made out of glass, silver, and polymer. The advanced design hybrid organic-inorganic materials enables highly efficient roll-to-roll manufacturing processes for large-scale commercial use
Certifications and Test Reports
How it works?
Components of the Film
Constantly emits infrared radiation which absorbs the heats of the applied object and releasing it to the outer space
Reflects the UV rays and other visible lights
Transparent and Flexible Polymer
Makes the film easier to be applied and install
Changi Airport, Singapore
The Best Airport in the World.
The world's sixth busiest airport.
Annual electricity charge of 600 million Singapore Yuan in which 300 million is used for air-conditioning, and the Terminal 5 under construction is 1.2 million square meters
Normal PLB 45.3°C
PLB with Radi-Cool Film 31.7°C
Foxconn (Iphone Manufacturer in China)
9 billion Kw/h used by 30 million sqm workshops in Foxconn China.
Foxconn and Radi-Cool signed Global Strategic Cooperation Agreement on 15th Jan, 2019.
Radi-Cool will start large scale application on Foxconn Longhua factory and Vietnam factory soon.
Base Model House
Temperature difference between Radi-Cool Model House and Base Model House can reach 16°C without air conditioner.
Foxconn Testing Result
Test location: Shenzen
On sunny days (June 14-16), the daily electricty saving rate is above 60%
On rainy or cloudy days (June 12-13), the daily electricty saving rate is 30% - 35%
Qinzhou Wine Warehouse
Located in Qinzhou, Guangxi Province of Southern China.
The indoor air temperature is maintained at 20±2℃ while the ambient temperature is frequently above 30 ℃ for much of the year from April to October; the roof temperature can reach over 60℃ in hot summer days.
Radi-Cool transparent films were installed on Windows in July 2018 for Phase I and 8,000 Radi-Cool reflective film will be installed on the roof for Phase II.
The only free zone port in western China, an important window for economic and trade cooperation between China and ASEAN
The wine warehouse occupies an area of 8600m2, with an indoor temperature of 20 ± 2 ℃, the temperature of the color steel roof is over 60 ℃, which results in huge power consumption. Radi-Cool’s first commercial project.
Phase 1 was done (Transparent Radi-Cool Film on windows), Phase 2 is under application on 11,000 sqm roof.
