Charging and Testing Unit for Prestolite Accumulator
The charging and testing unit is used to charge Prestolite accumulator with nitrogen or to check or to change the existing pre-charge pressure in the Prestolite accumulator.
For this purpose, the charging and testing unit is screwed onto the gas valve of the hydraulic Prestolite accumulator and connected via a hose to a commercial nitrogen bottle (please see below).
If the nitrogen pressure is only to be checked or reduced, the charging hose does not need to be connected. The unit has a screw-type fitting with a built-in gauge, check valve and a spindle for opening the accumulator gas valve to control the pressure.
