Helium

Helium (He) is a colourless, odourless, non-toxic, non-corrosive and non-combustible gas. It is mainly sourced from natural gas wells.

Helium is valued as a gas for lifting, breathing, leak detection, shielding, its inert properties and as a liquid for cooling. Many industries can benefit from its unique properties to optimize performance and productivity, reduce labor costs, and make operations safer.
