high quality CE certified liquid oxygen & nitrogen making plant uses Cryogenic air separation method, which is a traditional method to separate nitrogen and oxygen from air. Through air compressor/cooler and purification system, compressed air is cooled and water/impurities are removed from it. With expander supplying coolant nitrogen and oxygen are separated by fractionating method in fraction tower. Both gaseous and liquid gases are available as per users’ requirements. Features: ² high quality CE certified liquid oxygen & nitrogen making plant is of full low-pressure orthoflow expansion process, using molecular sieve purification system, air bearing turbo-expander and aluminum plate-fin type heat exchanger which greatly enhance the stability, security and reliable of operation. ² The fractionating column adopts aluminum sieve plate column, whose plate rectification achieves the best effect after being precision calculated and manufactured by us, so the height of column is reduced. The oxygen & nitrogen recovery ratios of the column are high and the output regulating range is large. ² high quality CE certified liquid oxygen & nitrogen making plant are reasonable and the occupation area of the plant is small. It can be operated easily and various data can be monitored by on-line digital indicator. ² Comparing to the full low-pressure reflux flow expansion process, the pure nitrogen output of the plant is higher.
