From 2012 to 2013 Yara Germany realized a comprehensive process optimization at the plant in Brunsbüttel. The ammonia factory is worldwide unique: both gasification lines can either be run on natural gas or oil. One component are the 5“ shut-off ball valves from Hartmann Valves. These are especially designed for the challenging combination of pure oxygen, steam and high temperatures. All customer demands have been fulfilled above-average. The energy efficient production secured the economic future of the facility.

We could not accept any risk during this project. With the wrong supplier we would have endangered the conversion, both technically and time-wise.

Hartmann has the reputation being known as the “Mercedes“ among the valve suppliers. For this important conversion we have made the decision for a high quality solution!
