Générateurs d'azote

L'air que nous respirons est composé d'environ 78 % d'azote et 21 % d'oxygène, les 1 % restants étant constitués d'autres gaz en quantités infimes, tels que le néon et l'hydrogène. Un générateur d'azote est capable de produire un flux continu et ininterrompu d'azote gazeux à partir d'air comprimé propre et sec. Il utilise un lit de tamis moléculaire au carbone (CMS) où l'oxygène et les autres gaz à l'état de traces sont adsorbés de manière préférentielle et où l'azote peut passer à travers.

Standard, SEP et MultiSEP

Les capacités vont de 1 à 1 150 Nm3/heure, avec une pureté comprise entre 95 % et 99,9995 %. Les générateurs PSA CompAir sont conçus pour fonctionner 24 heures sur 24, 7 jours sur 7. La commande à écran tactile dispose d'une interface conviviale avec une fonction de démarrage/arrêt automatique en fonction de la consommation de gaz. Nos séries SEP et MultiSEP sont équipées de colonnes à ressort qui empêchent l'écrasement du tamis moléculaire.

Sa conception unique assure un débit d'azote élevé et constant avec un encombrement minimal. Associé à une protection contre l'humidité par tamis moléculaire, il réduit considérablement les coûts et prolonge la durée de vie des générateurs.

• Significant cost savings over cylinder or liquid supply provides a typical return on investment of less than 24 months

Nitrogen is used for a wide range of industrial applications including atmosphere packaging for perishable food products. It is also used in preventing fire and explosions in chemical plants. Using high quality compressed air to supply the generators, ensures long and trouble-free service and guarantees optimum performance.

CompAir has a comprehensive range of systems that include everything needed to set up an on-site nitrogen generation system. CompAir air compressors and pre-treatment packages include adsorption dryers and coalescing filters to guarantee the highest quality air supply for the generators. The gas can be produced from your existing system with a minimum of additional floor space.

Typical gas supply methods include high pressure cylinders, liquid mini tanks or bulk storage vessels. A CompAir generator makes the workplace considerably safer for employees, eliminating the safety risks associated with traditional methods. When compared to outsourced supplies, on-site nitrogen generation offers a greater flexibility and has a significant impact on time and costs.

Nitrogen generators begin with clean, dry compressed air to create a continuous supply of high purity nitrogen.

The unique multi-bank design (CN2009P to CN2168P) enables additional generators to be added in the future as demand increases and provides redundancy for ease of maintenance. Your CNP Series nitrogen generator can grow with your company. In the diagram above you can see a typical on-site nitrogen gas generation station which uses compressed air.

From left to right in the image above you can see the air compressor (left), air tank to store the compressed air, then dryers & filters to remove water vapour & oil / impurities from the compressed air, then another air tank to store this clean air. The 4 nitrogen generators are shown on the right - they extract the N2 from the compressed air which is stored in the 4 tanks on the right hand side until needed by the process in question.
