Nitrogen for packaging goods
Many foodstuffs change their consistency as a result of contact with oxygen. This is due to enzymes that set metabolic processes in motion under the influence of oxygen. The consequences include discolouration and spoilage of the foodstuff. In order to delay this process, the packaging of foodstuffs for transport and the time until consumption is realised with the aid of the shielding gas nitrogen. To this end, nitrogen is added to the packaging to displace the oxygen. This nitrogen atmosphere keeps food fresh and durable for longer without the addition of preservatives. This MAP method (Modified Atmosphere Packaging) is mainly used for oxygen-sensitive foodstuffs such as meat, fish, yoghurt and cheese.
But even electronic components can be protected from ageing processes by being packaged in nitrogen dry packs. For this purpose, the components are packed in special bags to which desiccants are added. These are vacuum-sealed and welded after nitrogen flushing. The "removal of oxygen" allows electronic components to be stored safely for a number of years.
With our nitrogen generators, we supply high quality solutions for the stationary and mobile production of nitrogen for different applications, including for low volume requirements.
