SolarFrost History
SolarFrost provides research and development (R&D) services for cooling machines
powered by thermal energy, provided by solar collectors, district heating or waste heat.
SolarFrost cooling machines replace conventional air conditioning products powered by
non-renewable energy sources. Our vision is to make this new technology available
worldwide, to the benefit of consumers and the environment
