Magnetek introduced the first North American commercial installation of the Quattro regenerative elevator drive at the Emily Morgan Hotel in San Antonio, Texas. As a result of using the green technology of Magnetek's Quattro elevator drive, the Emily Morgan Hotel will receive $16,865 in commercial energy rebates from the local utility CPS Energy as part of rebate program offered in 2007 by San Antonio City Public Services. Quattro drives were installed as part of an elevator modernization project at the hotel, which is one of the most widely recognized landmarks in downtown San Antonio. One of the objectives of the project was to improve the efficiency of the elevator's energy consumption.
This study, with actual before-and-after energy consumption measurements taken in a side-by-side 17-day operating period during modernization, demonstrated a 45% reduction in watt-hours, a 78% reduction in volt-amp hours, and a 31% reduction in peak-demand charges with the Magnetek Quattro drives in place.
Quattro is an optimal choice for use on large DC motors. Isolation transformers and ripple filters are no longer necessary, and because of near unity power factor, there is less loading of the AC feeder lines to the elevator equipment, which eliminates the need for larger feeding wiring to the elevator. Magnetek's Quattro allows for efficient reuse of an existing DC motor, offering additional cost savings to the Emily Morgan Hotel modernization project. The Quattro provides energy savings, lower installation costs, and superior ride quality. The regenerative and low harmonic technology of Quattro is the green solution for yesterday's, today's – and tomorrow's – buildings.

By replacing antiquated elevator motor controls with Magnetek energy-saving Quattro DC adjustable speed drives with clean utility side harmonics and regenerative technology, the CityCenter Building elevators are today able to achieve 38 percent daily energy savings based on an average of 500 runs per day by each car. Magnetek Quattro drives used in the modernization project are designed to consume the lowest energy possible and their precise, accurate controls provide smooth acceleration and deceleration, resulting in both superior ride quality and reliability.

Magnetek provided smoother acceleration and deceleration to the Apollo House's elevators, also resulting in improved ride quality. Quattro DC Drives are designed so they can be converted for use with AC motors. This allows the property owner to modernise with these energy efficient DC drives now without changing the motors, but allows the flexibility to convert to AC motors in the future.
Dallas, TX
As Dallas' premiere Class A, multi-purpose business complex, The Crescent houses office spaces, hotel accommodations, restaurants, and retail shops. To effectively transport the large number of people that work in and visit The Crescent office building every day, a more energy efficient solution was required to replace an aging elevator system.
