One Seven® foam concentrate was specifically developed for optimal:
- Environment safety
- Flowing abilities
- Penetration ability
- Foam generation at a very low proportioning rate
- One Seven® class A only 0.3%
- One Seven® class B-AFFF only 0.5%
- One Seven® class B-AFFF-AR only 0.6%
To guarantee a fast penetration of One Seven® solution into the fuel, the foam concentrate has a very good moisture penetration ability even at a low proportioning rate.
One Seven® class A foam concentrate was developed to have the best moisture penetration ability at a proportioning rate of only 0.3%. This can be confirmed at any time by the so-called Draves-Test: Under same test conditions and with the same test time conventional foam concentrates first start penetrating the fuel and the sinking started after approximately 128 seconds, One Seven® achieved this in 28 seconds!
