Nitrogen gas is widely used as an assist gas for laser cutting, especially for stainless steel, carbon steel, aluminum, and other metal materials. Using 99.99% high-purity nitrogen helps reduce oxidation during laser cutting and can produce cleaner, smoother, and brighter cutting edges. Laser cutting typically requires high-pressure nitrogen at around 15–30 bar. Since a standard

Spheroidizing annealing is an important heat treatment process for carbon and alloy steel wire rods. During the process, 99.99% nitrogen is commonly used as a protective atmosphere. Nitrogen helps reduce contact with oxygen, minimizing oxidation, scale, and surface discoloration and helping maintain a cleaner wire rod surface. For continuous production, an onsite PSA nitrogen generator

For applications requiring ultra-high-purity nitrogen, a conventional PSA nitrogen generator may not be enough. A standard PSA nitrogen generator can typically achieve nitrogen purity up to 99.9995%. However, when customers require purity levels such as 99.9999% and extremely low impurity levels, an additional nitrogen purification system is required. Kerong Gas offers a Hydrogen Deoxo Nitrogen

Kerong Gas has successfully completed the factory testing of a 5 Nm³/h Modular PSA Nitrogen Generator. The testing video and performance data were shared with the customer for review, and the customer was highly satisfied with the results. The customer’s requirement was 5 Nm³/h at 99.5% nitrogen purity. During the actual factory test, the system

At Kerong Gas, every detail matters. Our skilled technicians are carefully welding the piping for a 5 Nm³/h Modular PSA Nitrogen Generator designed for a food processing plant. The system delivers 99.5% nitrogen purity and features a hygienic modular design. All gas-contacting components are made from stainless steel or high-strength corrosion-resistant aluminum alloy, providing a

Kerong Gas has successfully completed a 25 Nm³/h PSA Nitrogen Generator with 99.99% nitrogen purity. The system features two operating modes to provide greater production flexibility: This unit was ordered by a multinational chemical company as its third PSA nitrogen generator from Kerong Gas. The previous two units, supplied three years ago, have been operating

Kerong Gas has successfully manufactured and installed a 450 Nm³/hr PSA Nitrogen Generator with 99.995% nitrogen purity for an electronics factory. The nitrogen generation system has been integrated with the customer’s liquid nitrogen system under a unified control platform, ensuring a stable and reliable nitrogen supply for semiconductor chip packaging applications. This project demonstrates Kerong

Kerong Gas has successfully completed the factory performance testing of an Explosion-Proof PSA Nitrogen Generator for a customer in the Middle East. The system is designed to deliver 40 Nm³/hr of nitrogen at 99% purity (maximum oxygen content of 1.0%). During the final factory test, the generator exceeded the guaranteed specifications, consistently producing approximately 40
