The goal is 100% availability. 100% commitment from GRADERT on the way to this goal.

Choosing a machine and system retrofit is always an alternative to a new investment. Due to many years of experience in a wide variety of maintenance measures, we know where risks are hidden and that a well-planned retrofit process reduces these to a minimum and gives you deadline and production security.

Advantages of a GRADERT retrofit

Advantages of a GRADERT retrofit

  • Lower investment costs than compared with the installation of a new machine/system
  • Increase in system and machine availability, reduction of downtimes
  • Re-use of proven machine components
  • Less staff training required as the machine is largely known
  • No new and therefore lengthy approval process
  • Time savings compared to rebuilding
  • Energy saving and resource conservation
