BASIC INFORMATION ABOUT AIR

Air consists of :

NITROGEN - CSN

TYPES OF NITROGEN GENERATORS

CRYOGENIC GENERATORS

PSA GENERATORS

( carbon molecular sieve )

MEMBRANE GENERATORS ( fibres )

NITROGEN - CSN

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% )

NITROGEN - CSN

TECHNOLOGY MEMBRANE

• Fibres are able to separate O2 molecules ( smaller ) from N2 ( bigger )

• N2 with purity 95 ÷ 99 %

O2

CO2

dry N2

SOME APPLICATIONS OF NITROGEN

• Tyre shops • Tyre inflation cars and trucks

• Spray painting applications

• Food channels

TYRE INFLATION

TYRE INFLATION

WHY USE NITROGEN INSTEAD OF AIR ?

NITROGEN - CSN

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

NITROGEN - CSN

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

NITROGEN - CSN

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

NITROGEN - CSN

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

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 wheelFilling 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 wheelFilling pressure: 10 bar.

* Average by four tyre shops

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.

SPRAY PAINTING

NITROGEN - CSN

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 %

FOOD CHANNELS

NITROGEN - CSN

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 )
