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.

HYDAC piston and diaphragm accumulators can be charged and checked without the need for adapters. However, bladder accumulators require an A3 adapter, which is included in HYDAC’s scope of delivery.

The HYDAC Charging Kits allow maintenance personnel to check the current gas precharge pressure of an accumulator.

HYDAC charging and gauging units allow hydro-pneumatic accumulators to be precharged with dry nitrogen. For these purposes, a charging and gauging unit is connected to a commercially available nitrogen bottle via a flexible charging hose.

Charging of the accumulator is accomplished by simply attaching a HYDAC charging kit to the gas valve on top of the Permanent Gauging Block in exactly the same manner as attaching to an accumulator without the Permanent Gauging Block.

The HYDAC FPK250 charging and gauging unit allows hydro-pneumatic accumulators to be charged with nitrogen.
