CLIENT REQUIREMENT:

Auxillary cooling towers for the new power station

SOLUTION:

Two, four-cell, concrete induced draught cooling towers have been built to reject all the heat from the various auxiliary processes that support the six power generating units. Each cooling tower cell is designed to reject 27.6 MW at a flow rate of 1106 L/s to provide sufficient cooling to the various end users on the power station. Each cooling tower cell is fitted with a 30-foot fibreglass fan that is electrically driven to establish the air flow through the cooling towers. These fans are driven with variable speed drives to provide considerable energy savings for the client.

Currently we are nearing final handover for the complete project with minor construction activities and commissioning remaining for the Eastern Plant. At completion of this project it will be rewarding to see how this green field project materialised to be a superstructure that overlooks the adjacent farmlands. IWC’s cooling towers can clearly be seen on either side of the plant. We look forward to seeing how the towers perform as soon as the commissioning activities take place on site.
