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 O2 depending 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 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.
