HYDAC Corporation – Accumulator Division offers charging and gauging units to monitor and precharge Accumulators.

To maintain system performance HYDAC recommends that Accumulator gas precharge pressure be checked on a regular basis. A loss in the gas precharge will cause a drop in the system efficiency and could cause damage to the bladder, diaphragm, or piston 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.

These units also allow maintenance personnel to check the currrent gas precharge pressure of an accumulator. For critical systems, consider the use of a permanent gauging block which will allow constant monitoring.

All HYDAC charging and gauging units incorporate a gauge and check valve in the charging connection, and a manual bleed valve with a T-handle.

Adapters are available to precharge various Accumulator designs.
