Product description Brand name and product description

Isobar is designed to keep vaccines at the ideal temperature for places where electricity and other facilities are scarce, it works on the principal of Einstein refrigeration system developed in 1906. The system uses ammonia as the refrigerant and 2-phase refrigeration brings the cooling effect. The device uses a propane burner or electric heater to separate the vapors of ammonia and water to bring the cooling effect. Isobar uses an automatic valve which helps in evaporation of Ammonia into the original chamber and gives a powerful cooling effect. Isobar maintains stable temperature control (2-8 ˚C) up to 30-days. The product is in the prototyping and development phase.
