Achieved goals

  • So far, operation has been trouble-free with no additional effort required. The twin system has already proven its performance capabilities.

  • Degassing commenced in continuous operation before now being performed at regular intervals, which saves even more energy. By the same token, the pressure maintenance pumps only switch on when needed (whereas they used to run continuously).
