Hi-line Industries launches on-site nitrogen and oxygen generators

Supplier to the compressed air industry, Hi-line Industries, has recently announced its new line of N2 and O2 high purity, low energy nitrogen and oxygen generators.

The generators feature a range of advanced functions, including O₂ analyzers and energy control as standard. The technology employed at Hi-line for N₂/O₂ generation is based on simple PSA (Pressure Swing Absorption) procedures. Twin-tower carbon molecular sieve (CMS) beds absorb and regenerate to remove either N₂ or O₂depending on requirements. This allows users to generate nitrogen at the purity required for the application, such as 95% or 98%.

Among the areas where the uptake of Hi-line’s N₂/O₂ generators has been particularly high is MAP (Modified Atmosphere Packaging), a technique used for prolonging the shelf life of fresh or minimally-processed foods such as meat, fish, cheese, fruits and vegetables.

Although Hi-line offers a standard range of generators for N₂/O₂, each generator is customised in line with user requirements. Before a PSA nitrogen generator is manufactured, Hi-line carries out a free site survey of N₂/O₂ usage, and at what rate/purity. The team will also assess energy costs versus the current cost of gas and present a proposal indicating the potential savings available.
