Oxygen USP 


Present in abundance in nature, the oxygen molecule represents in weight 21% of the air we breathe. It also represents in weight 46% of the earth’s crust (in the form of oxides, of silicates, etc.), 89% of the water present on Earth (under molecular state), and 62% of the human body (under molecular state). Oxygen is a colorless, odorless and tasteless gas, and it is essential for sustaining life.

Oxygen therapy is the administration of oxygen enriched air as a medical intervention, dispensed mainly to improve the quality of life for patients suffering from chronic or acute ailments such as COPD (chronic obstructive pulmonary disease). Oxygen is also effective in the treatment of cluster headaches, a rare but extremely painful relative of the migraine.

Bulk Oxygen Systems

In order to use Oxygen from a bulk cryogenic vessel there must be a transformation of the liquid into gas. Cryogenic liquids are converted to gaseous state using a vaporizer. The most common type of vaporizers are ambient finned tube vaporizers. The fins absorb the warm ambient air and transfers the heat to the cryogenic liquid flowing in the tube. The heat transfer converts the liquid into a gas.
