Kerong Gas continues to push the boundaries of PSA nitrogen generation technology. Our advanced PSA Nitrogen Generators can achieve nitrogen purity up to 99.9997%, with oxygen content no higher than 3 ppm, without requiring an additional nitrogen purification unit. Even more impressively, with a standard refrigerated air dryer, the system can achieve a nitrogen outlet […]

Kerong Gas Cabinet-Type PSA Nitrogen Generators provide a stable, high-purity nitrogen supply for reflow soldering, wave soldering, selective soldering, and PCB and component storage. By creating a low-oxygen protective atmosphere, nitrogen helps reduce oxidation, improve solder wettability, minimize soldering defects, and enhance product reliability. With a compact cabinet design, low energy consumption, stable nitrogen purity,

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
