A common cause at a petrochemical company in Saudi Arabia

“Initially we were very concerned and I imagine the customer were reconsidering our relationship,” recalls Juergen Kohler, Alfa Laval Manager for Service in Saudi Arabia. “However, once we responded and they saw the lengths we were willing to go to fix it, they decided they wanted to work with us to find a solution.”



Customer's voice

From the very start we had a good understanding and good cooperation on all levels. After many meetings and investigations by both companies, we actually discovered that there wasn’t just one root cause, but many causes.
