environmental friendly and used in all kinds of refrigeration equipment
Property and application:
ISOBUTANE is an excellent refrigerant which has a high refrigerating ability ,low power and the load temperature rise is slow. At room temperature, it is a colorless ,transparent ,non-toxic,non-flammable liquefied gas under the autolokgous pressure .Refrigerant can replace R12
