Many buyers ignore daily evaporation rate when purchasing liquid oxygen tanks, while it directly affects static loss, refilling cycle and long-term operating cost. The daily evaporation rate refers to the percentage of liquid oxygen naturally vaporized per day under static storage. Liquid oxygen tanks reduce heat ingress by vacuum insulation in the interlayer. Vacuum level, insulation materials and welding sealing quality jointly determine evaporation performance. High-quality tanks have tight vacuum interlayers with low daily evaporation rate. Pressure rises slowly and venting is rare during static storage, which reduces oxygen waste. Once vacuum fails, continuous heat ingress accelerates vaporization, and safety valves open frequently, leading to heavy loss.

The standard daily evaporation rate varies by tank volume. Small tanks have larger specific surface area and naturally higher evaporation rate than large tanks. Cross-comparison of figures between different volumes is unreasonable. Buyers should check factory test reports of the same specification.

Daily evaporation rate is critical for factories with intermittent oxygen supply, night shutdown or holiday stop. Evaporation loss continues during standby. Tanks with poor insulation require frequent pressure relief within a few days, wasting oxygen. Low-evaporation liquid oxygen tanks are preferred for medical oxygen stations, remote mines and field cutting sites.

Do not only compare prices. Request vacuum inspection reports and factory evaporation test data for acceptance. Liaoyang Jinding Low Temperature Equipment Co., Ltd. strictly tests vacuum performance and controls daily evaporation rate of liquid oxygen tanks to cut long-term loss for customers.
