Additional bottles type B consist of a seamless cylindrical pressure vessel made of high-tensile steel. They have one connection of 3/4” BSP ISO 228 and one of 1” BSP ISO 228.
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 bottles type, such as forged “B” version, shell of bladder accumulator “ASS” and “ASSA” versions or body piston type “AB” version.
