GFED Series – Air Separation Plants

GFED - Overview - main image - 100_7454 (2)

The GFED is a small air separation plant that produces liquid oxygen and liquid nitrogen by cryogenic distillation of cryogenic air. Capacities range from 4 to 7 metric tons per day.  The GFED is designed to minimize shipping and allow for rapid installation by providing the plant in three distinct, pre-piped and prewired modules: the main air compressor, the warm end module and the cold box.  All of the machinery is designed to be air-cooled so a source of low voltage power is the only required utility.  The plant systems are self-contained and can be completely installed outdoors, requiring only a simple foundation.  The entire plant ships in two 40-foot shipping containers.

 

The GFED plants are designed to meet the most severe operating conditions.  Over 50 GFED plants are currently producing liquid oxygen and nitrogen for medical, industrial, oil field and military applications in some of the most remote regions of the world.

GFED Series

The GFED is designed to minimize shipping and allow for rapid installation cost by providing the plant in three distinct, pre-piped and prewired modules: the main air compressor, the warm end module and the cold box.  The main air compressor provides feed air to the plant and includes an air filter, compressor, electric motor, lubrication system and air cooler.  The warm end module includes the air clean-up equipment including a chiller, adsorber and afterfilter and also houses the turbo-expander.
