Plant 1

Gear Wheel Excellence Center – Plant 1. is the oldest production hall in Pratt & Whitney Kalisz.

The FDGS (Fan Drive Gears System) line joined in 2017 as another line in a group of specialized production lines, oriented in five departments. As a result, we are also a part of the program for producing the most modern engines used in the aviation industry – Pratt & Whitney Pure Power PW1100G.

Each of the production departments in the plant has separate control units as well as a management center in which planners, technologists, masters and manager are located. In total, Plant 1 has 11 production lines, a hardening line, a non-destructive testing facility, packaging and maintenance. Our team has about 500 people.
