TA..XI – flexible API design

API 613 spur gear units adapted and technically enhanced to meet the highest requirements; instruments and documentation suitable for specifications in the field of oil and gas engineering.

The turbo gear unit of the TA..XI type is based on a single-stage gear unit concept for high-speed applications with variable center distances and housing widths, which are optimized precisely according to the respective applications. These gear units are primarily used in the oil and gas industry as well as in the field of energy production. This range holds the world record as the most powerful gear unit in the turbo gear unit market with an output of 140 MW. They are designed according to API, AGMA, ISO, and DIN and set the standard for turbo gear unit technology in terms of quality, efficiency, and availability.
