Innovative Cooling System for Aggregates
The aggregate cooling system developed by Keckeis Systems is fully automated and saves up to 40% energy compared to flake ice systems.
In environments with high ambient temperature and strong solar rays special measures to reduce the concrete temperature are required. Traditionally large quantities of concrete have been cooled with flake ice. With the ever increasing demand for high-quality concrete the addition of flake-ice is limited due to the maximum allowable water content. Flake-ice cooling only cools the surface of the aggregates, the inside of the coarse aggregate is still at a considerable higher temperature.
Innovative energy saving technology
Our system to cool the coarse aggregate is not only working fully automated but also with low energy input. Compared to the traditional system of cooling, our system can save up to 40% of energy consumption.
With the cold water cooling system developed by Keckeis Systems the coarse aggregates will be cooled completely meaning the concrete has a temperature, after mixing, which is in line with the required temperature on site.
For coarse aggregates with size 10/20 two watertight silos are installed as active storage where in each the coarse aggregate is cooled by means of 6 °C cold water. Whilst a further two two silos are producing cooled concrete. The cold and mixing water is provided by means of cold water chiller and stored in cold water tanks.
