AAK has been designing gas-reduction units in North Africa for over 5 years. We have realized more than 20 high / medium / low gas pressure units between Algeria and Tunisia so far. In collaboration with our Algerian partner we have realized gas-reduction groups from 76 bar to 250 mbar, being for the major part industrial plants on-site, gaining the international certification and the approbation of the competent local authority. As regarding installations in Algeria, AAK units are partially tested and approved here in Italy, to be afterwards assembled and started by our local partner.
