IWC Australasia was awarded a contract to design and construct two new pultruded cooling towers with the support of its sub-contractor UGL.

These cooling towers mark an important development for Callide, which is a major generator of electricity for the sunshine state.

The project initiated a transformative phase, demolishing the existing wooden cooling towers and erecting new mechanical draught counter flow cooling towers with a  Glass Reinforced Plastic (GRP) structure. The two IWC cooling towers each comprise 18 cells and stretch over 200m.

Designed in accordance with standards CTI STD-137 and CTI STD-152, these towers offer a host of advantages. Pultruded GRP has emerged as the material of choice for large, field-erected cooling towers due to its extended service life, rapid deployment capabilities, and reduced construction durations. Moreover, these towers exhibit chemical and corrosion resistance, high impact strength, and a remarkable combination of rigidity and lightweight design.

The decision to embrace pultruded technology is not just a leap forward; it’s a strategic move towards sustainability and efficiency. Unlike their wooden counterparts, pultruded cooling towers promise not only long-term reliability but also shorter construction timelines.

After months of hard work and extraordinary effort from the IWC Australasia team and sub-contractors, one of the units at Callide is back in operation and, as the project nears completion, the anticipation for the full restoration of the units has the industry excited.
