At what temperature do refrigerated liquefied gas cylinders operate?

Refrigerated liquefied gas cylinders operate at extremely low temperatures due to the nature of the gases they contain. These gases, such as liquid nitrogen or helium, need to be maintained at temperatures significantly below the freezing point of water to remain in liquid form. Operating around -238°F (-150°C) allows these gases to stay in a stable liquid state, which is crucial for their storage and use in various applications, including scientific and industrial processes.

Maintaining such low temperatures prevents the liquefied gases from vaporizing into gas and ensures their efficacy and safety in handling. Other temperature options do not align with the requirements for refrigerated gases, which need to remain well below the freezing point to prevent phase change from liquid to gas, leading to potential safety hazards.
