Applications
Metallurgy
Our nitrogen generators are extensively used across the metallurgy industry for applications such as annealing, sintering, nitriding, and furnace purging. They are especially well-suited for heat treatment, bright annealing, protective heating, powder metallurgy, copper and aluminum processing, magnetic material sintering, precious metal refining, and bearing production—ensuring a stable, inert atmosphere for high-temperature processes.
Oil & Gas
Designed for both onshore and offshore operations, our nitrogen systems serve critical roles in nitrogen blanketing, pipeline purging and replacement, emergency leak repairs, enhanced oil recovery (EOR), pressure maintenance, and LNG processing. They support safe and efficient production while minimizing contamination and fire risks.
Chemical
In the chemical industry, our nitrogen generators are applied for inerting, purging, pressurizing, cleaning, pneumatic conveying, and protection during sensitive chemical reactions. They are also widely used in chemical fiber manufacturing, oxidation prevention in wire drawing, and nitrogen charging in synthetic fiber production.
Manufacturing , But Green
Green is not only KSTK’s brand color---it represents our core philosophy. It stands for our commitment to energy efficiency and environmental protection. Through high-efficient, low consumption gas solutions, we help customers reduce costs and operate sustainably. We aim to lead the industry toward carbon neutrality and contribute to global environmental progress.
