Liquid Oxygen (LOX) Generator – 5 GPH
Liquid Oxygen (LOX) Generator

Liquid Oxygen (LOX) Generating Plant. The Liquid Oxygen Generator produces 5 GPH of LOX. It uses vacuum swing adsorption to produce gaseous oxygen which is then liquefied using a close loop nitrogen refrigeration system. The plant is designed to produce and store the liquid oxygen on board US Navy aircraft carriers.


Liquid Oxygen (LOX) / Liquid Nitrogen (LIN)
2.0 TPD or 5.0 TPD

Modular Liquid Oxygen/Liquid Nitrogen Generator

Designed for applications, including commercial requirements for LOX/LIN, where it is not required to relocate the units on a regular basis. Designed with four modules that can be transported in ISO containers. The modules are erected at the operating site and connected with prefabricated piping spools that are shipped with the unit – fully operational in less than two days. Available in two sizes, the smaller unit produces 2.0 tpd while the large unit produces 5.0 tpd.

GAMMA Liquid Oxygen/Liquid Nitrogen Generator

The PCI GAMMA Liquid Oxygen/Liquid Nitrogen Generator is designed to be transportable on a C-130 aircraft. It can be deployed and operational in extreme remote locations in under four hours. The plant can also produce high pressure Gaseous Oxygen (GO2) or Gaseous Nitrogen (GN2) for filling cylinders. This self-contained plant, built on a 463L pallet, will fit in a C-130 aircraft, can be flown to a forward area, and generate LOX in under four hours. The primary product is Aviators Breathing Oxygen, but these plants also produce Nitrogen for servicing tires, struts, and accumulators on fighter aircraft.

Dry-Air Purging Unit

Dry-Air Purging Unit

The Air Purging Unit is used primarily for purging liquid oxygen storage and transfer tanks. This unit is designated as: GSU-62/M, NSN 3655-01-561-4006, Purging Unit, Air, Liquid Oxygen Storage Tank.

A dry-air purge system is more common than nitrogen. External compressed air is fed into a desiccant dryer system before being used to purge the chamber air.

The unit consists of a motor, blower, electrical power box assembly and heater assembly, mounted to a trailer. System piping for the air flow interconnects the drier to the blower, the blower to the heater assembly and the heater assembly to the service hose. The enclosed housing has four latched, top- hinged doors on the sides. The rear of the housing has a heater access door for removal of the heater element when required. The trailer chassis is of welded channel construction with forklift channels and is supported by a four-wheel running gear with a hand brake. The chassis frame has a rear pintle hook which allows tandem towing of other vehicles, swivel tie-down rings for securing the trailer during transportation and reflectors for road safety.

*These plants are offered with manual, semi-automatic or fully automatic control.
