  1. NITROGEN

  2. BASIC INFORMATION ABOUT AIR Air consists of :

  3. TYPES OF NITROGEN GENERATORS CRYOGENIC GENERATORS PSA GENERATORS ( carbon molecular sieve ) MEMBRANE GENERATORS ( fibres )

  4. TYPES OF GENERATORS WE HAVE CHOSEN THE MEMBRANE GENERATORS ( FIBRES ) WHY ? Membrane generators PSA generators • Small dimension Big dimension • Less complicated technology More complicated technology • Less maintenance cost More maintenance cost • Lower purity ( 95-99% ) High purity ( 99.5% )

  5. dry N2 O2 CO2 TECHNOLOGY MEMBRANE • Fibres are able to separate O2 molecules ( smaller ) from N2 ( bigger ) • N2 with purity 95 ÷ 99 %

  6. SOME APPLICATIONS OF NITROGEN • Tyre shops • Tyre inflation cars and trucks • Spray painting applications • Food channels

  7. TYRE INFLATION

  8. TYRE INFLATION WHY USE NITROGEN INSTEAD OF AIR ?

  9. TYRE INFLATION WITH AIR • Pressure loss of 0.08 bar/month. ( O2 + H2O exit through the rubber ) • Oxidation ( rust ) of wheels • Oxidation of the rubber

  10. Under inflated Correctly inflated TYRE INFLATION THIS CAUSES UNDERPRESSURE: under pressure consumes tyre lifetime safety - 0.2 bar + 1% - 10% + skidding - 0.4 bar + 2% - 30% + skidding - 0.6 bar + 4% - 45% + skidding

  11. TYRE INFLATION WITH NITROGEN • Reduces the fuel consumption • Reduces the danger of skidding • Reduces the number of inflations ( three time less than air ) • Reduces the oxidation of the wheel and the rubber • Reduces by 75% the possibility of bursts caused by overheating • Increase tyre lifetime • Increased drive comfort • Constant temperatures

  12. TYRE INFLATION THE SITUATION OF THE MARKET IS : • Purity request for tyre applications > 95% • At present only 5% of the market uses nitrogen, but …….. It is growing and at that moment ……….. WE WILL BE READY WITH OUR NITROGEN SYSTEM

  13. TYRE INFLATION VOLUME OF NITROGEN CAR Tyre end pressure: 2.2 bar. Tyre volume around.: 32 l. at 1 bar. * Volume at 2.2 bar: 70 l. one wheel Filling pressure: 7 to 8 bar. TRUCK Tyre end pressure: 8 to 9 bar. Tyre volume around.: 204 l. at 1 bar. * Volume at 8 bar: 1600 l. one wheel Filling pressure: 10 bar. * Average by four tyre shops

  14. TYRE INFLATION WHAT ARE THE KEY BENEFITS OF NITROGEN GENERATORS COMPARED TO GAS BOTTLES ? • A constant supply ensured; you never have to worry about too late/early deliveries • Save space • Remove the risk and handling errors • No contract with supplier of nitrogen; simplify administration to save time and money. • No time waste changing the bottles, no handling costs.

  15. SPRAY PAINTING

  16. SPRAY PAINTING WHAT ARE THE ADVANTAGES TO USE NITROGEN ? • Still new concept • Reduced drying time for paint ( no humidity ) • Elimination of ever impurity that can deteriorate the quality of the paint • Regulating the temperature allows to reduce the flow pressure and for this reason you reduce the consumption of solvents with 30 % • Reduction of solvent in atmosphere: better ambient • Purity request: 99 %

  17. FOOD CHANNELS

  18. FOOD CHANNELS THE MOST COMMON APPLICATION OF NITROGEN • Food packing ( coffee, fruit, cheese, ….. ) • Bottling of liquids ( wine, water, oil, ….. ) With nitrogen, we don’t have humidity and bacterium and for this reason the food is preserved better ( better quality )
