Three new ranges of nitrogen and oxygen generators (for on-site gas generation) have been launched by Atlas Copco Compressors.
The new NGM, NGP and OGP generators will enable companies to utilise their existing compressed air installation to generate their own nitrogen and oxygen, avoiding the operational and administrative costs of ordering, transporting and storing bottles or bulk liquid in cryogenic tanks, says the company.
The new membrane nitrogen generator, (NGM) is suitable for applications such as fire prevention, blanketing and tyre inflation. A bundle of polymer fibres acts as a membrane that allows nitrogen to pass and other gases (such as oxygen, water vapour and carbon dioxide) to permeate.
The company claims this membrane technology generates nitrogen with an adjustable purity between 95 and 99.5% and flows up to 500m³/h.
