The Benefits of MRL Technology

Energy savings The GT MRL uses PM gearless, synchronous AC machine technology. Typically a power factor of 1 is achieved, which means that 100% of the electrical energy to the machine is converted and output as mechanical energy. Highly efficient permanent magnet PM machines use rare earth magnets to generate magnetic field flux, so no external power is consumed by field windings. GT MRL power savings vs a traditional holed hydraulic elevator is over 60%. Power savings vs a traditional geared traction elevator is over 25%.

Environmentally friendly

Since the GT MRL system uses no hydraulic oil, there is zero risk of a spill causing environmental contamination, and potential cleanup liability.

Superior ride quality

The GT MRL elevator is a gearless system, widely recognized for providing the smoothest possible ride with the best overall motion control. For an investment similar to that of hydraulic elevators, ride comfort and performance are incomparable.

Reduced maintenance

Since the GT MRL system has no gearbox, mechanical aspects are simplified and maintenance all but eliminated.

Silent and odor-free

Unlike hydraulic systems utilizing pressurized hydraulic fluid, a pump reservoir, and liquid control valve, GT MRL systems are elegant in their simplicity. The MRL PM gearless machine is all but noiseless and it produces no hot hydraulic oil odor.

Reduced construction costs

The GT MRL system incorporates a small control closet which replaces the traditional machine room. Placed inside the insulated building envelope, the control system closet requires no cooling.

Superior structural and aesthetic design

Even the most basic GT MRL package includes an upgraded elevator cab and upgraded fixtures. Options to customize include panoramic elevator cabs; stone, stamped exotic metals , custom wood paneling, matched wood panels, glass wall panels, and countless other upgrades that provide a unique and prestigious identity for buildings that stand out from the ordinary.
