Nitrogen accumulator charging & testing kits

Hydrotechnik offer a selection of Nitrogen accumulator charging and testing devices for pressures up to 280 bar for use with bladder, piston or other similar style accumulators.

  • Our PC280/70-D Bladder accumulator charging kit & PCFPU280/70-U Bladder, Diaphragm or Piston accumulator charging kits are an economic choice for charging accumulators with 5/8" or 7/8"UNF, 1/4" BSP, Hydac Style M28x1.5 or Schrader style 5/16"UNEF/VG8 valves. The kits comes with a high pressure flexible microbore charging hose for easy finger tightening connection by hand to the Minimess test points fitted to the device and 5/8" BSP male UK gas bottle connector.
  • The new World Wide / Universal test kit has all the adaptors and connections to ensure that most of the Accumulators sold world wide are catered for.  Ideal for Service Engineers that have to deal with Bladder, Piston or Diaphragm type accumulators along with an easy to use high quality pressure regulator for easy setting of charge pressures from 10 to 235 bar.
  • Minimess Charging Units are available as stand alone charging devices or as complete measuring kits.
  • Our Minimess accumulator charging kits are designed to work with existing Minimess 1615 or 1620 accumulator charging valves although adaptors can be provided to connect to or replace 3rd party charging valves such as UNF, BSP or Metric threaded. Charging devices connect to your Nitrogen bottle and connects safely and easily via a high pressure flexible microbore charging hose to the Minimess accumulator valve. The microbore hose has minimess swivel female ends for easy finger tightening connection by hand. All kits come with pressure gauge calibration certificates on request.
