Inert Gas Generators

Inert Gas Generators (IGG) are systems designed to produce oxygen-deficient gas, typically by controlled combustion or nitrogen-generation technology, for tank inerting, fire prevention and explosion-risk reduction. They are widely used in oil & gas, marine, offshore and petrochemical operations.
