Comfort Line

Maximum ride comfort independent of load and temperature.


The hydraulic power unit with the electronic iValve guarantees maximum ride comfort, independent of load and temperature. The many options available allow it to be used in a wide range of locations, from new buildings to modernisation.

The Comfort Line can be supplied for hydraulic elevators for any required total loads and travel heights up to 25 m.

  • Optimised tank sizes, tailored to the floor area
  • Constant travel times, even with changes in load and temperature
  • Low energy costs
  • Wide operating temperature range
  • Short total travel time due to the short slow speed travel
  • In only a few cases does the oil need to be cooled
  • Down speeds can be increased by up to 50 % at no extra cost and without loss of comfort
Benefits for you:
