GREEN TECHNOLOGY

Green Technology. Standard on the Gen2 system.

Innovation meets sustainability.

Because being green is not optional.

At Otis, leadership is something that comes naturally. It began

when Elisha Otis changed the world by selling the first elevators
with safety brakes in 1853. With Elishas legacy as a backdrop,
Otis has grown into the worlds leading manufacturer and service
provider of elevators, escalators and moving walkways. And along

guiding principles for everything we do. As leaders, we improve

who we are and what we do each and every day. To us, its only
natural.

Regenerative technology

Energy is

Our ReGen drive, now standard on the

Gen2 system, puts electricity back
into your buildings grid by capturing
normally wasted energy. Thanks to low
harmonic distortion, this recycled energy
provides clean power minimizing impact
to your building's electrical system. All
this helps to make the Gen2 system up
to 75% more efficient than conventional
systems. And from an energy consumption
standpoint, the Gen2 system uses up to
40% less energy than non-regenerative
machine-roomless systems.

power will help reduce initial construction costs and monthly
electric bills. Please contact an Otis representative to discuss
if the single-phase power option can be used on your project.

PULSE
The Pulse system provides safety and peace of mind
with 24/7 monitoring of the Gen2s flat coated-steel belts.
It provides advance notice of belt wear by detecting
the slightest weakness.

OMMS
The Otis Maintenance Management System (OMMS)
is a predictive and preventative system, ensuring fewer
service calls and less downtime than any other plan
in the industry. Well focus on your elevator so you
can focus on your building.

At Otis, reliability is the hallmark of
