Product Description
The liquid nitrogen generator (liquid nitrogen machine) consists ofthree parts: a nitrogen generator (internal orexternal), a refrigeration equipment (gas liquefaction equipment), and a Dewar tank, The whole machine has aone-click automatic liguid replenishment function, and the equipment automatically starts when the liquidnitrogen in the liquid nitrogen tank is below the set liquid level. The manufacturing of liquid nitrogen machineadopts the principle of mixed working fluid throttling refrigeration, which gradually cools nitrogen from theambient temperature to the saturation condensation temperature ofnitrogen liquefaction. The lowest coolingtemperature ofthe refrigeration mechanism can reach -196 'c, and the liquefed liquid nitrogen in therefrigeration evaporator is transported to the liguid nitrogen tank for storage to obtain liquid nitrogen. Theequipment automatically detects the liquid nitrogen level in the Dewar tank
