Essential M.A.P. gases and gas mixtures

WHEN THE SHEL LIFE OF THE PRODUCT DEPENDS ON THE GAS USED

The most used gas is often a mix of nitrogen (N2), carbon dioxide (CO2) and potentially oxygen (O2). Argon (Ar) is also increasingly offered for these same properties of neutral gas as nitrogen (N2).

Each gas has a clearly defined main role

    • Nitrogen (N2) and argon (Ar) eliminate the traces of air and humidity,

    • Carbon dioxide (CO2) prevents the development of bacteria,

    • Oxygen (O2) keeps the colour of red or reddish meats.

Companies recognised for their expertise

 

For a mix of gases with more than 20% oxygen (O2), Henkelman proposes the O2 oxygen pump option for all the models that can take the gas flushing option.
