Features at a Glance

  • Prototypes: Upright and chest refrigerator models.
  • Can be used as a vaccine cooler or as household or small commercial refrigerator.
  • Energy storage in ice-packs through the use of direct current compressor — no lead battery required.
  • Powered by 3 X 60W photo-voltaic panel — no contribution to global warming and no electrical grid required.
  • AC / DC converter — provides flexibility to use wind, hydropower, bio-gas or grid energy (or car battery in case of exceptional cloudy period).
  • Energy efficiency through efficient insulation.
  • R-600 hydrocarbon compressor and cyclopentane blown insulation foam — no contribution to ozone depletion or global warming.
  • Temperature control through natural convection between ice storage compartment and vaccine compartment — no electronic control devices required.
  • One SolarChill unit can serve a population of 50,000 people for preserving vaccines.
  • Expected commercialization price between $1,500 to $2000 (including solar panels) — 50 to 60% cheaper than currently available solar refrigerators meeting World Health Organization specifications.
  • Up-right model has the potential to enter the domestic market in remote, off the grid areas of developed as well as developing countries.
  • Estimated need in developing countries for vaccine storage purposes is between 10,000 to 20,000 per year.
  • Potentially high market demand for domestic and small commercial refrigeration applications in regions of developed and developing countries that are off the grid or have unreliable electrical services.
