The ThyssenKrupp ISIS was ThyssenKrupp's machine room-less elevator for the North American and European markets, first introduced in 2001 or 2002. ThyssenKrupp made the ISIS and ISIS II. The ISIS was made from 2004 to 2005. The ISIS II was made from 2005 to 2007.

Overview

The ThyssenKrupp ISIS is a machine room less traction elevator designed for low to high-rise buildings for the North American and European markets.

North America

In North America, the ThyssenKrupp ISIS used the "K-Core" rope instead of conventional steel rope. The K-Core was a kevlar rope that was made exclusively for the ThyssenKrupp ISIS elevators. ThyssenKrupp claimed that the rope is stronger than steel ropes and last longer. The ISIS elevator features a smaller machine installed in the shaft pit (for regular ISIS only), eliminating the need of a machine room. This saves up to 60 square feet of building space. ThyssenKrupp ISIS was also easy and faster to install because of its lightweight components, which only required 10 days to complete the installation. ThyssenKrupp developed the ISIS elevators as a mean to counter the disadvantages of hydraulic elevators.

ThyssenKrupp ISIS elevators were available only as low rise models, until 2005, before the ISIS II came out. During this time, the blue Aurora fixtures were for low rise only. A unique feature of the ISIS/ISIS 2 is lanterns on the sides of the doors. The ISIS II appears to have been merged to 1 model for low and high rise. The ISIS/ISIS II can usually be told apart from other ThyssenKrupp elevators by the chimes, which are often chimes unique to ISIS/ISIS II. ThyssenKrupp ISIS and ISIS II can usually be told apart by the fixtures. The ISIS had a different indicator than the ISIS II, which had the same indicator as Signa4 fixtures. Sometimes, ThyssenKrupp ISIS/ISIS II elevators can have other fixtures. The model of an ISIS is ISIS low/mid-high rise capacity number. Example: "ISIS mid-high rise 4500". The model of an ISIS II is ISIS first two numbers of capacity. Example: "ISIS 40". There is also the ISIS 50H. The difference between ISIS 50 and 50H is unknown.

Europe

ThyssenKrupp ISIS was also available for the European markets, which was made in France. It features a centered pulley block drives which enables an installation everywhere. It has a speed of 1 meter per second, maximum capacity of 1000 kilograms and can serves more than 10 floors.

Seattle Children's Hospital accident

On October 9, 2007, an accident happened at a children's hospital in Seattle, WA, United States, where the cables broke on an ISIS elevator, sending the elevator into free fall before the safety governors engaged to stop the elevator car on the fourth floor. Many ThyssenKrup ISIS elevators were inspected during that time. ThyssenKrupp deemed them safe, but city of Seattle elevator inspectors deemed some of them dangerous, and had ThyssenKrupp replace the cables with conventional steel cables. ThyssenKrupp thought about adding an extra safety device for all ISIS elevators nationwide, but then decided to start replacing the cables with conventional steel cables nationwide. Also, ThyssenKrupp ISIS elevators were known to break down a lot.

After the accident, ThyssenKrupp discontinued the ISIS elevators and replaced them with the Synergy series. The Synergy series was originally introduced in 2005 for markets outside North America.
