Why is liquid nitrogen so expensive in Brazil?
Liquid nitrogen has long been a key cold source infrastructure in many fields, such as medical care, life sciences, industrial cutting, and food preservation, due to its cryogenic properties and wide adaptability. However, in recent years, the Brazilian market has been faced with a headache: the continuous rise in the price of liquid nitrogen, unstable […]
Oxygen Generator Troubleshooting Guide: Error Codes and Solutions
Whether in hospitals, factories or remote project sites, equipment alarms often come suddenly, the user’s greatest fear is not a machine failure, but “do not know what the alarm means”, worried about “is not to shut down”, and even more do not know “Should I handle it myself”. This makes many non-technical people feel anxious […]
How to Install a Liquid Nitrogen Generator
A liquid nitrogen generator (LN2 generator) is indispensable in modern industries, medical applications, food freezing, and research laboratories. Proper installation of the liquid nitrogen generator not only affects its gas – production efficiency and service life but also ensures the safety of operators. As a global leader in the liquid nitrogen equipment manufacturing industry, MINNUO […]
How Often Should You Service Your PSA Oxygen Generator?
In today’s oxygen-dependent industries—whether medical, industrial, or remote infrastructure—uninterrupted gas supply is not just desirable, it’s critical. Yet many operators underestimate the impact of irregular maintenance on PSA (Pressure Swing Adsorption) oxygen generators. Over time, small issues like clogged filters or sensor drift can silently degrade oxygen purity, trigger false alarms, or even force costly […]
