Design Specifications

Isobar is based on Einstein cooling technique or absorption refrigeration system which uses ammonia and water as refrigerants. The device turns ammonia into vapors which are then passed through a small orifice using an automatic control valve that brings the cooling effect. The device is designed to carry a specified load carriage for rural trips. The device is capable of delivering 8 kg of load in a 1.6 L unit that is capable of delivering dosages in rural areas.  It can be sustainably recharged in an hour using a 900 W heating element for day-to-day use and a propane burner that can be recharged on-the-go in case of emergency for up to 30-days. The device meets the international standards for temperature safe vaccine distribution which if not followed leads to vaccine freezing and potency. Isobar maintains stable temperature control (2-8 ?C) up to 30-days.
