ALNAT ENDO: The Protective Atmosphere  [ Return towards  Gases  ]

Adapted to a large range of applications:



A Unique Opportunity...


The ALNAT™ Endo atmosphere is based on the catalytic reaction at high temperature between Air and an Hydrocarbon such as natural gas to produce an active protective atmosphere containing H2 and CO species, preventing from decarburising or oxidizing the treated parts.

Advantages : Atmosphere is highly adapted to non decarburizing applications

- All the Oxygen is consumed during the catalytic reaction
- CO2 level is very low
- Complementary Nitrogen dilution is integrated to adjust the atmosphere characteristics to your process requirements

Customized To Your Needs...

Thanks to our equipment flexibility, we will provide you with the most appropriate solution that will fully meet your demand in regard to your flow need, and atmosphere composition.
The concentration of main active species and the flowrate are independant parameters that can be adjusted for each of your production needs.

With a Complete Quality Control Follow Up...

The Quality of the atmosphere we deliver is continuously controlled and regulated at different production steps to guarantee you the highest performance capabilities !


- Mass Flow regulators on raw gases (Air, Hydrocarbon, N2 )
- Oxygen probe to regulate the catalytic reaction (Air / CxHy ratio)
- CO / CO2 / CH4 analyser to master the atmosphere quality delivered to your furnaces

ALNAT™ Endo Web Services will provide you with an internet access to your data where you will be able to trace your atmosphere quality.
