Problem
Many structures and surfaces, from buildings to vehicles, absorb solar radiation and retain heat, leading to increased energy consumption for cooling, elevated operating temperatures for equipment, and uncomfortable conditions in outdoor environments. Traditional cooling methods rely on energy-intensive systems that contribute to greenhouse gas emissions and strain resources.
Solution
Coldrays offers a suite of passive daytime radiative cooling (PDRC) materials designed to reflect sunlight and emit heat into the atmosphere without requiring electricity or water. These materials, available as films, coatings, and fabrics, can be applied to a variety of surfaces to reduce cooling demand, lower operating temperatures, and improve overall energy efficiency. By reflecting solar radiation and dissipating heat through radiative cooling, Coldrays' products provide a sustainable and cost-effective alternative to conventional cooling technologies.
Target Audience
Coldrays serves a diverse range of customers, including building owners, facility managers, agricultural operations, transportation companies, and manufacturers seeking to reduce cooling costs, improve energy efficiency, and enhance thermal management in various applications.
