Due to the erosion identified in the initial investigation on performance drop, extend the investigation into a study of the internal flow characteristics of the air cooler header boxes and undertake thermal simulation to determine the optimum solution and modifications necessary to both remove the potential for excessive erosion and attain overall performance increase for the coolers.

Undertake modifications of the equipment, supervise installation and commissioning and monitor.

The solution included a re‐configuration of internal header design to remove the risk of excessive erosion and, through Jord’s innovative design, re‐use of existing monel tubes.

Erosion vortex eliminated significantly extending the life, reliability and performance of the air cooler.

Jord’s revised design attained a 12% increase in thermal duty.

50% reduction in the capital cost originally estimated by client as necessary to resolve the problem.
