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. WE HAVE CHOSEN THE MEMBRANE GENERATORS ( FIBRES )
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. TECHNOLOGY MEMBRANE O2
CO2
dry N2
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. WHY USE NITROGEN INSTEAD OF AIR ?
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. THIS CAUSES UNDERPRESSURE:
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
Under inflated
Correctly inflated

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 WE WILL BE READY WITH OUR NITROGEN SYSTEM
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: 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. WHAT ARE THE ADVANTAGES TO USE NITROGEN ?
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. THE MOST COMMON APPLICATION OF NITROGEN
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 )
