To begin with, we can separate the HYDAC Charging Kits into two categories:
- The charging and testing units. The HYDAC universal charging and testing unit FPU, used to charge bladder, piston and diaphragm accumulators with nitrogen. Therefore, it also helps to test and alter the pre-charge pressure.
- The nitrogen charging units. The HYDAC N2-Server, used for the charging of accumulators, helps indeed for supplementing the pre-charge pressure and/or for the charging of accumulators stations.
