Airox Nigen Equipments Pvt. Ltd. Manufactures Ammonia Cracking Based Hydrogen Gas Generator. Airox Nigen Equipments Pvt. Ltd. Supplies adsorption based gas generators and air & gas drying equipments. Ammonia Cracking Based Hydrogen Gas Generator produces cracked ammonia [ NH3] gas using anhydrous ammonia from cylinders. Ammonia Cracking Based Hydrogen Gas Generator has cracked ammonia which contains 75% Hydrogen and 25% Nitrogen and the product gas is very dry & oxygen free. In heat treatment furnaces, this gas has wide use as reducing atmosphere. The dissociation of ammonia gas takes place in the presence of a Nickel Catalyst at temperature of 850 Deg C. To 900 Deg. C. In an electrically heated or fuel fired automatic furnace.
