Heide Refinery –
part of the Klesch Group
In 2010, Heide Refinery became a proud member of the Klesch Group, an independent, global company that has specialised in the safe and efficient operation of refineries. The Klesch Group, founded in 1990 by A. Gary Klesch, pursues a strategy of long-term value creation through targeted investments, operational excellence and the commercial optimisation of industrial assets.
In addition to Heide Refinery, the Klesch Group also operates Kalundborg Refinery in Denmark and Ruhr Oel Refinery in Germany.
Since the refinery was acquired by the Klesch Group, roughly 490 million euros have been invested in order to improve processes and boost efficiency in Heide. What’s more, the number of processed crude oil types has tripled and the product portfolio has been optimised. Thanks to these measures, Heide Refinery is now one of the most reliable refineries in Germany and sets industry standards.
