SolCold Glacier Sun-Powered Cooling Film

SolCold is a company founded in 2016 and based in Rehovot, Israel, that develops outdoor cooling coatings powered by sunlight. It aims to reduce dependence on electricity for cooling exposed assets such as containers, warehouses, server rooms and silos, which overheat under strong sun.

Its Glacier products are self-adhesive films made of non-toxic organic polymers that combine three mechanisms: reflecting up to 98.5% of solar radiation, converting heat into higher-energy visible photons through anti-Stokes fluorescence, and releasing heat through radiative cooling. The range includes Glacier 110 for containers and electronics enclosures, Polar 90 for large roofs and a cooling fabric for sewn applications. SolCold sells B2B to industrial operators, utilities and logistics companies, with custom-made solutions.

• Three cooling mechanisms: solar reflection, anti-Stokes fluorescence and radiative cooling in one film.
• Glacier 110: premium self-adhesive film for containers and electronics enclosures.
• Polar 90: lower-cost film for warehouses and large-footprint sites with fast payback.
• Cooling fabric: flexible textile for caps, gazebos, coverings and umbrellas.
• Savings calculator: online tool to estimate cooling and energy savings.
• Non-toxic materials: organic polymers with no rare-earth metals and no chemical emissions.

Energy storage and telecom operators in Vietnam can apply Glacier 110 to battery containers and equipment shelters to lower internal temperature. Breweries and food processors can cover silos and tanks to cut cooling energy. Warehouse owners in industrial parks can trial Polar 90 on metal roofs to improve working conditions.

The film provides 90-170 W/m² of cooling power without electricity and keeps surfaces up to 7°C cooler than shade under direct sun. Customer quotes on the site report 30% lower cooling consumption in Israel Electric Corporation server rooms and over 30% energy savings in AB InBev steeping silos. Installation is simple, with no wiring, and maintenance is limited to occasional washing with water.

Heat waves are stressing power grids and raising cooling costs for outdoor equipment and storage. In tropical Southeast Asia, telecom shelters, battery storage containers, cold chain logistics and warehouses face year-round solar heat gain, increasing interest in retrofit passive cooling that pays back within a few years.
