The Rise of Machine Room-Less (MRL) Elevators in Commercial Buildings

Elevators have come a long way over the years, and one of the biggest changes we've seen is the introduction of machine room-less (MRL) elevators.


At Metro Elevator, we are always looking for ways to improve our services, and MRL elevators are a big part of that. These elevators offer several benefits that make them a great choice for many commercial buildings.


What Are Machine Room-Less Elevators?

Traditional elevators need a separate room to hold the machinery that makes them work. This room, called a machine room, is usually either located above or next to the elevator shaft. While this setup has been used for a long time, it takes up extra space in a building.

MRL elevators, however, don’t need a separate machine room. Instead, the machine is placed inside the elevator shaft itself. This design saves space, allowing a smaller room or closet to house the elevator controller, mainline disconnect, and elevator car lighting disconnect.


That said, it’s important to note that certain regulations still apply. In California, the Department of Industrial Relations (DIR) and other authorities having jurisdiction (AHJ) require that a control room be designated for MRL elevators. This room must house the necessary equipment to ensure accessibility and safety. Even though MRL elevators eliminate the need for a traditional machine room, these regulatory requirements must be followed to comply with safety standards.


Because of these benefits and evolving regulations, MRL elevators are becoming more popular in both new buildings and upgrades to existing ones.


The Benefits of Machine Room-Less Elevators 

  1. Saves Space

In commercial buildings, every square foot is valuable. By not needing a large machine room, MRL elevators free up space that can be used for other purposes like adding more offices, storage, or common areas.


The compact design of MRL elevators also gives architects more freedom in planning the building layout. Without the need to set aside space for a conventional machine room, building designs can be more efficient and creative. This is especially important in cities where space is limited, and every bit of usable area matters.


  1. Cost Savings

Building a separate machine room adds to construction costs, so not needing one can lower the overall cost of a project. This is particularly helpful in large commercial buildings where every bit of savings adds up.


In addition to lower construction costs, MRL elevators are designed to save conventional machine room space. Over time, this can lead to lower costs for building owners, making MRL elevators a smart long-term investment.


At Metro Elevator, we work closely with building owners to find cost-effective solutions. We believe MRL elevators offer great value for their price, and we’re committed to helping our clients get the most out of their investments.


  1. Energy Efficiency

With rising energy costs and a growing focus on sustainability, energy efficiency is more important than ever. MRL elevators are a great choice for those looking to reduce their energy use.


Traditional hydraulic elevators use a lot of oil and electricity, which can be expensive and harmful to the environment. MRL elevators, on the other hand, use energy-efficient motors that consume less power and regenerative drives. This not only helps the environment but also lowers energy bills for building owners.


Our team understands that sustainability is a key concern for many of our clients. By offering MRL elevators, we help our clients reduce their environmental impact while also saving money on energy costs.


  1. Better Passenger Experience

How an elevator feels to use is important for the people who ride it every day. MRL elevators are designed to provide a smoother and quieter ride than many traditional elevators.

Since MRL elevators don’t need a conventional machine room, there is less noise from the machinery. This makes the ride quieter, which is especially nice in places like offices, hotels, and hospitals where a peaceful environment is important. A quieter elevator creates a more pleasant experience for everyone.


  1. Safety and Reliability

Safety is always our top priority, and MRL elevators are no exception. These elevators come with advanced safety features that meet or exceed industry standards. For example, they have backup braking systems, emergency communication devices, and other equipment for automatic rescue operations in case of a power failure.


MRL elevators are also known for their reliability. This means less downtime and fewer disruptions, ensuring the elevator is always available when needed.


At Metro Elevator, we take safety seriously. We thoroughly test our MRL elevators to ensure they meet the highest safety standards. We also provide regular maintenance to keep our elevators running smoothly.


How MRL Elevators Compare to Traditional Elevators

When choosing between an MRL elevator and a traditional elevator, it’s important to consider what your building needs. Each type of elevator has its own advantages.


Traction Elevators

These are often used in tall buildings where speed and capacity are important. They require a machine room and are usually more expensive to install and maintain, but they can move quickly and handle heavy loads.


Hydraulic Elevators

Hydraulic elevators are typically used in low- to mid-rise buildings. They cost less to install but are less energy-efficient and require a machine room. They also tend to have a shorter lifespan because of the wear on their hydraulic parts.


MRL Elevators

MRL elevators are a good middle ground between traction and hydraulic elevators. They are ideal for low- to mid-rise buildings and offer benefits like space efficiency, cost savings, energy efficiency, and a smooth ride. While they might not be the best choice for very tall buildings, they work well in most commercial settings.


Applications in Low to Mid-Rise Buildings

MRL elevators are especially suited for low- to mid-rise buildings, such as office buildings, hotels, retail spaces, and residential complexes. These buildings don’t need the high-speed capabilities of traction elevators or the heavy-duty power of hydraulic elevators. Instead, they benefit more from the space-saving, cost-effective, and energy-efficient features of MRL elevators.


Office space thanks to space saving elevator

For example, in a five-story office building, not needing a conventional machine room allows for more office space, which can be rented out. In a mid-rise hotel, MRL elevators help create a quieter environment for guests while also reducing energy costs. In retail spaces, the space saved can be used for more store area or storage, making the building more functional.


Metro Elevator specializes in MRL elevator solutions that fit the specific needs of your building. We work closely with architects, developers, and building owners to ensure our elevators meet the highest standards for performance and reliability.


The Future of Elevators in Commercial Buildings

As buildings continue to evolve, the demand for efficient, cost-effective, and sustainable solutions will grow. MRL elevators are likely to play a big role in the future of commercial buildings because they offer so many advantages.


With locations across the United States, we stay up-to-date with the latest elevator technologies to provide the best solutions for our clients. Whether you’re in New York, San Francisco, or anywhere in between, our team is here to help you explore the benefits of MRL elevators and decide if they’re the right choice for your project.


In conclusion, smaller, non-conventional machine rooms are an exciting advancement in elevator technology. They offer benefits like saving space, lowering costs, using less energy, providing a better ride, and ensuring safety and reliability. As buildings become smarter and more focused on sustainability and comfort, MRL elevators will be a key part of the future.
