Accumulator systems


DESCRIPTION

An accumulator system is an energy reserve, grouped in cylinders (accumulators) that can use bladder or piston technology. Ideal for managing reserves or recovery actions, they are composed of a frame that holds one or more accumulators, equipped with safety locks and rupture disks.

Connected together, they maximise the energy storage capacity and optimise use of space, allowing installation in specific areas of the installation. In some cases, they allow rationalisation of the power unit layout, saving on total space required. Duplomatic offers its hydraulic and build-related expertise to create effective accumulator systems with reduced dimensions, certified in line with the strictest standards, starting from the PED directive.

Certifications:

  • PED 2014/68/EU, ASMEIX, ISO 9606-1:2017 for welding processes, 2006/42/EC Machinery safety

 

Control processes:

  • WPS, PQR, NDT, PM.
