Our operators are impressed with the Cardox. This is due to its effectiveness at removing build up, it saves manual work and is safe to use.”

We have used the Cardox System twice since the training session. Once was an opportunity during a shut. The second time to break a ring. This shortened the Kiln down time by at least 3 days - Cardox has paid for itself already.”
