From the world's tallest towers to community hospitals, Otis engineers, installs, and maintains vertical transportation systems that keep people moving safely in 200+ countries.
Otis designs and maintains elevator and escalator systems engineered for the specific demands of each industry.
High-rise MRL and gearless traction systems for towers 5–100+ floors. Gen3 series delivers 30% energy reduction.
Indoor and outdoor commercial escalators with customizable step widths, balustrade options, and energy-saving sleep modes.
Horizontal and inclined moving walkways for airports, convention centers, and large transit facilities.
Extend elevator lifespan by 15–25 years with Otis modernization packages — controls, drives, fixtures, and full-cab upgrades.
Otis is committed to reducing the environmental footprint of vertical transportation through energy-efficient systems, renewable energy use, and circular maintenance practices.
Our ESG CommitmentsOur regenerative elevator drives recover kinetic energy during braking and return it to the building's power grid — reducing elevator energy consumption by up to 75%.
Our global manufacturing facilities operate under ISO 14001:2015 environmental management certification, with a commitment to zero-waste production targets by 2030.
Otis modernization services extend elevator service life by 15–25 years, reducing the environmental cost of full unit replacement and diverting materials from landfill.
"We specified Otis Gen3 elevators for our 42-story headquarters tower. The destination dispatch integration with our access control system was seamless, and lobby wait times dropped by nearly 40% compared to our previous installation."
"When we modernized our 1980s hospital elevators with Otis, the bed elevator dimensions and antimicrobial cab materials were exactly what our infection control team required. The OtisONE monitoring has been invaluable for our facilities team."
"The escalator installation at our international terminal is handling over 45,000 passengers per day without interruption. The preventive maintenance contract gives us confidence that we won't face the operational disruptions that plagued our previous supplier's equipment."
Our engineering team addresses the most common questions from project managers, specifiers, and building owners.
Ask Our EngineersOEM Service (e.g., Otis): Technicians trained exclusively on the manufacturer's equipment have direct access to proprietary diagnostic tools, firmware updates, and genuine parts warehoused locally. OEM contracts often include contractual uptime SLAs (e.g., 99.9% on Otis Premium) and remote monitoring integration (OtisONE) that independent firms cannot replicate. The trade-off: OEM contracts typically carry a 15–30% price premium over independent alternatives.
Independent Maintenance Companies: Third-party contractors can service multiple brands, which is advantageous in mixed-brand buildings. Pricing is often more competitive, and some independent firms have strong local response networks. The limitation is that proprietary diagnostic access and genuine parts warranties may not be available, which can affect mean-time-to-repair on complex faults.
Our recommendation: For mission-critical facilities (hospitals, airports, Class A office towers), OEM service with remote monitoring provides the lowest total cost of downtime. For low-rise residential or light commercial applications, a qualified independent maintainer meeting local inspection standards may offer better value. Request maintenance cost benchmarks for your asset class before committing.
The uptime case for IoT: Connected monitoring systems have measurably reduced unplanned callbacks. Buildings running OtisONE have reported an average 50% reduction in emergency service calls compared to their pre-activation baseline. For a hospital or data center where elevator downtime directly affects operations, that ROI is straightforward.
The cybersecurity concern: IoT connectivity introduces attack surface risk. Elevator control systems connected to building networks can, if misconfigured, become entry points. This concern is legitimate — the European Union Agency for Cybersecurity (ENISA) identified building automation systems as an emerging critical infrastructure threat vector in its 2022 threat landscape report. Otis addresses this through encrypted data transmission, air-gapped control logic (the elevator runs on local firmware — cloud loss does not stop the elevator), and ISO 27001-aligned data handling.
Verdict: For buildings with IT/OT security governance in place, smart monitoring delivers demonstrable operational benefits with manageable risk. Buildings with limited IT oversight should implement OtisONE on an isolated network segment with firewall policies reviewed by a qualified building systems integrator before activation.
