Additional bottles type AB consist of a pipe of high-tensile steel. The same pipe of the piston accumulator type AP.
The additional bottles are used to take in and store nitrogen to increase the gas volume in the accumulator station (with bladder or piston accu- mulator). This means that smaller accumulators can be used for the same gas volume and costs can be reduced. EPE offers a wide selection of bottless type, such as forged “B” version, shell of bladder accumulator “ASS” and “ASSA” version or body piston type “AB” version.
