The standard commercial gas bottles are usually loaded at 100-120 bar. For applications wherein the hydraulic accumulators need to be filled with higher pre-charge pressure beyond 120 bar and above, calls for need of additional tools / equipment. Booster unit is the product to facilitate this job.
The Accumulator booster unit is typically a mini hydraulic system consisting of oil supply unit with a piston accumulator, that works as compressor for nitrogen / inert gas.
The desired pre-charge pressure is set first by means of digital display and then once machine is started the piston accumulator compresses the nitrogen gas. This continues till the set pre-charge pressure is reached, upon which the charging process is complete and ends automatically.
Our N2-Servers or Booster units are suitable both for charging and for supplementing the pre-charge pressure in all standard diaphragm, bladder and piston accumulators and also accumulator stations (bladder and piston accumulator stations)
