Innospin Power Plant Systems


Innospin is an independent engineering company with a long track record of successful projects in power plant systems.

Air-cooled steam condensers – design and engineering

During hot or freezing days, in deserts or urban areas, at high cross wind conditions, at full load or part load operation, in constraint or in open space, for renewable or conventional energy production, our supplied and installed air-cooled condensers are tailor designed and optimally integrated into our client’s power plant, delivering the highest possible efficiency and power production during the whole year, reliably, year after year, decade after decade.

This is our expertise, our commitment and our passion.

We have used our approach to realise more than 45 projects, working together with a wide range of customers in China, the Middle East, Asia and Europe. Our ACCs condense steam from turbines with a total power output of 22,300MW, using more than 2’100 cooling cells and 8.5 million metres of heat-exchanger tubing.

Air-cooled steam condensers – supply

Innospin can supply the complete air-cooled steam condensers as a turnkey installation.

On the other hand, Innospin offers as well to supply the key performance components together with the complete ACC design while our clients may choose to execute the steel structures and installation. The benefit of such tailored and shared business contracts is to the advantage of our client to optimize their investment cost while Innospin ensures and guarantees for the performance of the installed air-cooled steam condenser.
