Airfield  Hydraulic Power Unit  LZH/N series II

Airfield hydraulic power unit LZH/N series II is designed to check the technical condition of the hydraulic systems while cleaning and refilling the working fluid of the aircraft in service in the Polish Armed Forces, including F-16 and C-130. It is provided with two independent inflow and outflow lines, also fit for parallel operation. The unit is mounted on a low chassis and fit for towing at speed up to 25 km/h.

Other parameters:

  • self-ventilated hydraulic system with independent cooling
  • tanks with air dryers
  • operating parameters recording
  • built-in unit’s tank filling/refilling system
  • filter contamination signalling
  • permitted operating temperature excess signalling
  • trailer with light signals and backlit operator panel LZH/N series II is powered from TN-C or TN-S three-phases a.c. mains
  • rated voltage 3 x 230 V / 400 V
  • frequency 50 Hz
  • rated load current 200 A

The unit is adapted for air transport.
