For Oxygen plant air separation unit, both internal and external compression are relative to the compression of oxygen. Internal compression means that the liquid oxygen obtained in the fractionation tower is compressed to the pressure required by the liquid oxygen pump to fill the bottle, and then vaporized into gas in the fractionation tower through the hyperbaric oxygen heat exchanger. Go straight to the bottle; External compression means that the liquid oxygen in the fractionation column is not compressed, directly vaporized into gas out of the fractionation column, through the storage bag or buffer tank, into the piston type oxygen compressor compressed to the bottle filling pressure before filling the bottle.

Our company's Oxygen plant air separation unit is designed, developed and produced by professional personnel. The core component of the production is the air compressor. The accessories used in the production of the air compressor are well-known brands, with long service life and simple operation.
