Controlled heating of aggregates with hot air silo heating
The latest generation of Sauter heating system is supplied with modern PLC and visualization. In winter when the temperature is down to minus 15°C, if you want good quality concrete you need a heater for your sand and gravel silo and preheated concrete mixing water. The Sauter silo heating work with hot air in such a way that water-cement ratio is not affected. In continuous mode, the system heats the mineral at 15°C or more. With preheated mixing water from the boiler it is possible to increase the concrete temperature by additional 8°C. Hot air is blown directly onto the mineral and pulls up in the silo, which avoids selective heating and condensation.
