Modernisation OTIS Gen2:

IN 2000, the american company OTIS launched his Gen2. The Otis Gen2 system replaces conventional steel ropes with coated steel belts. The unique, patented  flat-belt drive technology virtually eliminates vibration, providing passengers and tenants a remarkably smooth, quiet ride and improved overall comfort.

For the safety of the passenger, the Gen2 elevator has a device called PULSE (Resistance Based Inspection, RBI, US patent), which monitors the belts status 24 hours and alerts the elevator technicians when a tear or damage occurs.

The Gen2 has more than 20 years and also some of them needs to get modernised. 


The Gen2 we can modernise:


1) Gen2 Comfort

This is a version for low to mid-rise buildings. 

The European version has three aesthetics model; Optima, Selecta, and Lumina.

Both Optima and Selecta has two LED lightings on the car station.

Lumina does not have LED lightings on the car stations, instead they are located on the ceiling.

The fixtures used are the Otis 2000 ones with either blue LCD or yellow Electroluminescent Display floor indicators.

Specs (European version):

  • Machine room less with permanent magnet synchronous motor

  • ReGen drive with closed loop vector control

  • 320/450/480/630/900/1000 kg capacities

  • 1 m/s speed

  • 45 m travel distance

  • Serves up to 14 floors

  • Up to 3 cars in a group

  • One or two entrances

2) Gen2 Flex

Gen2 Flex was made for new installation solutions for existing buildings.

This version has a much smaller capacity and because of that, it can be installed in narrow/limited spaces.

The maximum number of capacity is 630 kg. The position of counterweight can be on the side or rear. 


  • Machine room less with permanent magnet synchronous motor

  • Otis OVC variable frequency drive with closed loop vector control
