Orion S.A.

After spending over 6 unsuccessful months of CFD modeling to determine a satisfactory method of blending two fluegas streams at significantly different temperatures, we were running out of options. We contacted APEX for help and they offered their “Temperature Equalizer”. The Temperature Equalizer was installed in one of our North American Carbon Black plants and has proven to be a resounding success, mixing the two streams in extraordinary fashion. The APEX group solved the mixing issue with a very robust and effective design and we are very pleased with the results. – Orion-Americas Project Team - Orion SA


During the preparation, design and manufacturing process, we have been able to experience the cooperation with APEX as pleasant and the complete package meets the requirements as stated in the scope of supply. - Shell Replacement Team
