Solar Ice Maker Company

The ISAAC Solar Icemaker operates on the ammonia absorption refrigeration technology. Ammonia absorption is used in industrial and commercial refrigeration. In domestic refrigeration, it was replaced by modern refrigeration with the development of electricity and freon refrigerants long ago. But now it is important for small-scale uses because of the need to conserve electricity and fossil fuel and because of the needs for food security, especially in rural unelectrified communities.
