Oxygen generators

Laboratory nitrogen generator 32 to 500 lpm
 

Oxygen generators produce gaseous oxygen from compressed air on site and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid.

Oxygen generators are available with capacities ranging from 0,6 to 200 Nm3/hour at 95% purity. The design is made for round the clock 24/7 operation. Each generator is equipped with automatic start & stop function, enabling the generator to start and stop automatically according to the consumption. The touch screen control with various add on features is delivered as an option.

Pressure Swing Absorption(PSA) is the most commonly used non-cryogenic oxygen production process; most effective for small and medium capacities.

The process operates by using two columns filled with adsorbent, a molecular sieve called Zeolite. Pre-treated compressed air enters the first column and follows up through the Zeolite. Nitrogen and some other gases are being trapped while the oxygen is allowed to flow through. When the active column is saturated, the air flow is directed to second column. The first column depressurizes allowing nitrogen to be purged out to the atmosphere and completely regenerates. The process is repeated continuously, when one column is productive, the other regenerates and at the end of each cycle they switch roles. The generator produces constant flow of purified oxygen.

PSA Oxygen generator

Various industries such as aquaculture and the use of ozone generators require oxygen at various scales of production. For this, PSA oxygen generators are often used. PSA O2-Generators generates gaseous oxygen of a purity of 90 % – 95 % on the basis of the adsorption principle PSA (Pressure Swing Adsorption). The PSA process separates the naturally in ambient air existing oxygen (21 % oxygen, 78 % nitrogen, <1 % noble gases and other gases). This is a physical process. The compressed air passes a molecular sieve, which adsorbs nitrogen at a high pressure and releases it at a low pressure. The O2 generators are widely used for oxygen aeration active mud processes, re-aeration of surface water, fishes breed aquatics, industrial oxidation process (sewage treatment), humid oxygenation and more.
 We have PSA oxygen generator models in this range delivering oxygen from 300 liters per hour to 25 m3/h.

Nitrogen generators & production

How to Select an On-Site Nitrogen Generator

See this good article by the USA Parker brand nitrogen generators.

How to Select an On-Site Nitrogen Generator

On-site nitrogen generators are preferred over gas cylinders and dewars for many applications in the food and beverage industry including blanketing edible oils and packaging. Plants producing nitrogen in-house can realize a 50 percent gas cost reduction as well as savings related to improved operations efficiencies.  Additionally, a nitrogen generator eliminates the expense and CO2 emissions associated with truck deliveries. . .

On-Site Nitrogen Generation for Modified Atmospheric Packaging

This article by airbestpractices.com also provides a good overview.
In the food and beverage industry, the moment a product leaves the production line, the clock starts ticking down to when that product will no longer be viable for sale or consumption. To combat the clock, modified atmospheric packaging (MAP) techniques are used to help maintain product freshness and increase shelf life. Nitrogen is the most cost effective, efficient and widely used industry solution for a company’s packaging needs—whether it is for manufacturing cheese, coffee, dried snack foods, or fresh and ready-to-eat (RTE) foods. MAP also helps to decrease chances of contamination or spoiling, keeping products on the market for longer and ultimately increasing the reach of distribution . . .
