The Otis HydroFit is Otis' machine room less and machine room hydraulic elevator. It is not the first MRL hydraulic elevator, but it was the first MRL hydraulic elevator that became somewhat popular for new buildings. The HydroFit was introduced in October-December 2011.

Overview[]

The Otis HydroFit is a machine room less hydraulic elevator, but there is also a machine room model as an option. Since the middle of 2013, this is Otis' only hydraulic elevator model.

In MRL versions of HydroFit, the compact pump unit is installed on the side of the shaft, touching a pit. It is directly connected to the piston. Over that, the controller is located. All of these elements can be accessed from one door, making repairs easier than in any other MRL hydraulic elevator.

Machine rooms are required in some states (California, Massachusetts, New York City and Washington). The machine room version of HydroFit uses a larger pump unit, probably based on the same technology as used in HydroFit's standard MRL version, and uses the same controllers. Here, the pump unit is connected with piston using pipe, just like in normal hydraulic elevators with a machine room.

Starting in Circa 2021 or 2022, Otis is implementing Gen3 fixtures into the Hydrofit Model, including the LCD Lanterns with a faster paced chime as well as the Otis eView LCD Floor Indicators.

The Otis Hydrofit MOD is a modernization for hydraulic elevators introduced in 2024; the packages are available in Prime and Plus.
