Akhavan Kalantari Oxygen and Nitrogen Gas Company was established in 1325 in Tehran, as the first oxygen and nitrogen gas producer in Iran, and continues to produce gas and liquid nitrogen, oxygen, and dry air.
After the establishment and development of industrial units and enhanced oxygen and nitrogen gas demand in the country, managers established another plant in Gilan province, which was the first plant in this province. In 1357, this factory was moved to the industrial city of Rasht while increasing its production capacity. It is now working as “Akhavan Kalantari Industrial and Medical Gas Producer” in the field of liquid oxygen and liquid nitrogen production.
