MRL
MRL (Machine Room Less) Elevators are cost-efficient solution for architects, builders and building owners that uses less space and meets or exceeds today’s safety standards.
MRL elevators are the most compact systems available. By using compact permanent magnet, gearless machines, the need for a separate machine room has been eliminated. This reduces construction costs and makes MRL systems much easier and faster to install. After all, less space for the elevator means more space for the building and don’t require altering the superstructure of building roofs.
Permanent magnet motors are much more efficient and use less energy than many other systems, they do not require the use of contaminating lubricants making for a much cleaner and more environmentally friendly system.
If the building is expected to achieve LEED certification (Leadership in Energy and Environmental Design), it is very important to have systems that promote energy savings. In this way, energy-efficient elevators contribute to the overall energy savings of the building and therefore add to the prerequisite and credit requirements of LEED.
