In July 1999, several steel structures of the Electricity Department of the Port Elisabeth
Municipality were Zinganised. ZINGA was applied on jet fuel tanks and on inlet stacks. AQUAZINGA was applied on the exhaust
stacks for the hot fumes of a large turbine generator installation. These pictures show the 2 inlet stacks with filter systems, painted blue, and 2 exhaust stacks, protected with AQUAZINGA.
