I can confirm that CK/ INGO in Denmark have installed equipment from SECU -TECH on former Shell sites since 2017, to optimize the fuel delivery to our sites. O2PID have replaced older overfill systems and we are now using the combine Overfill and Cross-Over protection, that O2PID is supporting. The installation is provided by GVR in Denmark and only a few issues since installations, most related to Isolators and wiring.  

Our external fuel haulier companies have adapted the O2PID system with only positive feedback.
