The Gaztron’s Oxygen Generator (GOX-C Model) for cylinder filling stations sets a new standard in oxygen gas production, establishing itself as India’s premier manufacturer for cylinder filling purposes. Operating on a cutting-edge principle called pressure swing adsorption (PSA) technology, this advanced system ensures a continuous and reliable supply of high-purity oxygen gas for filling cylinders.
The operational process of the GOX-C Model begins with the intake of a gas mixture, typically air, which is pressurized and introduced into the generator’s adsorption vessel. Within this vessel lies the heart of the system – a zeolite adsorbent bed. Zeolite, known for its exceptional affinity for nitrogen, selectively captures and retains the nitrogen molecules present in the gas mixture as it flows through the bed. Meanwhile, oxygen molecules pass through more freely, leading to an enriched oxygen content in the outgoing gas stream.
With this unique adsorption process, the GOX-C Model can achieve an impressive purity range of 90% to 95%, adhering to stringent industry standards. The enriched oxygen gas is then utilized for filling cylinders at a high pressure of 140 Kg/cm2, ensuring a secure and reliable supply of oxygen for various applications.
The GOX-C Model’s efficient design includes four cylinder filling manifolds on each side, enhancing productivity and reducing downtime during the cylinder filling process. This feature allows for simultaneous filling of multiple cylinders, further increasing efficiency and output.
As the zeolite bed reaches its adsorption capacity, it undergoes a regeneration process to restore its adsorption capabilities. This cyclic operation ensures a continuous supply of high-purity oxygen by alternately adsorbing nitrogen and regenerating the zeolite bed.
Being India’s leading manufacturer of oxygen generators for cylinder filling purposes, Gaztron’s GOX-C Model stands as a symbol of innovation, reliability, and technological advancement in the field of oxygen gas production. With its impressive capacity range, wide purity range, and versatile cylinder filling capabilities, this generator meets the demands of various industries, medical facilities, and critical operations across the nation. Whether it’s for medical use, industrial processes, or any other purpose, Gaztron’s Oxygen Generator (GOX-C Model) guarantees the provision of premium-quality oxygen gas, reinforcing its position as the foremost choice for cylinder filling stations in India.
