For an innovative conversion of the ammonia factory Yara was looking for special shut-off valves for extreme conditions. “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!” says Werner Döring, Head of Projects and Availability, Yara Brunsbüttel GmbH. The 5“ shut-off ball valves from Hartmann Valves are especially designed for the challenging combination of pure oxygen, steam and high temperatures. Jürgen Rommel, ICA Engineering, is very satisfied with Hartmann’s products and service: “We could not accept any risk during this project. With the wrong supplier we would have endangered the conversion, both technically and time-wise”, The conversion to energy efficient production even secured the economic future of the facility.
